Z-Offset BLTOUCH With Marlin Firmware
ฝัง
- เผยแพร่เมื่อ 20 พ.ค. 2024
- I did a video a couple of weeks back on how to setup a BLTOUCH auto level system on an Ender 3 Pro, but felt I needed to go into more detail on how to properly set the Z-Offset. If the Z-Offset isn’t set correctly, you will have major first layer adhesion issues. In thios video, I go over the sull process to get the correct Z-Offset for your printer and show you how to actually set it. I also cover some of the issues I had with my extruder that caused the Z-Offset to change after a couple of prints.
If you have any questions on the content covered in this video, feel free to leave a comment below with them. I try to reply to all commented within 48 hours.

I hope you found this overview helpful! If you have any questions or would like other tips/tricks, just let me know in the comments.
You make good videos, man. Nice and to the point, but informative. You're not spending the whole time showing off how much you know with irrelevant bull$hit.
sure did find it helpfull, got it all dialed in
I did not have the option to set the z offset! What am I doing wrong
@@jmzthree It sounds like the bltouch firmware isn't there.
Hey, how do I get it to stop from oozing out when it’s finding all 9 points, my printer keeps messing up partially from the oozing and the other half it messes up I don’t know 100% why but like it prints on half of the bed and the other half it scratches the glass bed I have
You seem to be the only one who can explain this without taking 35 minutes, and while making sense. I have an Ender-3 with a 32 bit main board, and getting the BL-touch to work has been a lot of trial and error since it seems nobody has my exact setup. But thanks to your video, I've got a good first layer coming down, and I'm printing a test benchy.
Hi. Thanks for the feedback, im glad I was able to help.
Hey 3D Printscape and Oddman1980, I have the same setup, ender 3 with 4.2.2 mainboard and I also am having trouble with the BL Touch, so much so that I am thinking of removing it and going back to the good old ways. the main issue I have is when auto homing the display reads as 15.78 z axis. then the offset is down to around -5 but when I start to print, the nozzle is scraping and not allowing filament to extrude. I have to tune it while in motion, lifting the extruder by 1mm in some case but then the whole thing isn't level. honestly wish I hadn't bought it now. happy 3d printing
@@guraven you ever get this sorted? I’m having the same issue with an Ender Pro 5
@@cybertrophic Hi, I did get it sorted eventually, I watched more TH-cam videos and had to compile my own firmware following the instructions, I then updated the printer with that firmware and it worked, little fine tuning here and there but it worked.
For the firmware compiling I watched teaching tech and followed what he did, also google worked for me
Let me know if you need more help
Hope you sort it.
I too would like to thank you for this. I had experienced a lot of disappointment with the fact that I couldn't get the BLTouch to work. It sat unused for weeks in my frustration. Then TH-cam recommended this and I realized, hey, my carriage wobbles like crazy (I thought it was a feature for flexibility). I got everything set and now I'm off and running. Thanks again!
Hi. Thanks for the feedback and im glad to hear everything is working for you now.
I just want to say that this video and the guide on your website is the best bl touch guide I can find on the whole internet. After you install the firmware, all other guides just stop. You are the only person that correctly explains how to set up the offsets to let the bl touch do its job. Thank you so much!
Hi. Thanks for the feedback, i appreciate it.
Absolutely true and thanks for the video. Yet it´s a shame for Crealty not to do proper manuals. Before finding this video I already scratched my glas...
Man, your videos have been some of the best, easiest to watch, not too complicated or boring yet also informative and to the point, can't thank you enough for these man! I wish you many good prints to come 😂
Glad you like them!
@@3DPrintscape I am having some problems if you don't mind giving me some guidance, I set my z offset to how it's supposed to be till the paper starts slightly gripping, I save the settings, but when I start printing, it prints In the air (nozzle too high) what am I doing wrong?🤔
@@joshsmith7812 Hi. What was the z height when you ran the autohome and what were the rest of the values you came up with? Also, another thing to try would be to kick off a calibration print and adjust the z-offset while your printing if your firmware allows it.
@@3DPrintscape I've really messed up somewhere along the process, I'm really new to printing, is it possible to reset the Z axis on the Ender 3 pro?
Anyway, basically if I click bed level, and then I want to move the offset , the default value is: +010.0
I've also watched multiple tutorials and many people do it differently, I just want to print haha, aggh, I was getting some great prints before but getting my bed right all the time was a nightmare so I went the BL touch route, long story short I've been spent all day trying to get it right haha
@@joshsmith7812 I can reset the values by clearing the eeprom, that will put you back to stock settings. From there, try to run through the process again and see what you come up with.
after all the other videos, this was the only one that helped me to finally set that damn Z axis setting!! thank you very muchooo!!
Hi. Thanks for the feedback, im glad you were able to everything working.
I bought a new CR Touch and spent the last two days pulling my hair out, because every tutorial was useless because it made zero reference to this exact issue and assumed everything was working as expected. You saved my sanity and the CR Touch is working amazingly. Thank you so much.
Hi. Awesome, im glad i was able to help out :).
Hey, your videos have helped me out greatly more than once now, I'd just like to make a small suggestion, it would be really helpful to get a good view of your lcd screen when following along with your instruction. Thanks again!
Hi. Thanks for the feedback. I have been trying to get better at getting both the screen and printer in the video, it’s surprisingly difficult lol.
Thanks, great video! None of the other tutorials explained it this simply.
You're welcome!
Thank you for this! I just spent last two days messing with z offsets but had to re-center my brain with this excellent video. 👌
Glad it helped!
I followed both videos you have set the z offset but when i go to levele bed option it does the middle and then comes to the front right of the bed for the next point and then doesnt touch and go to the next measurement? If i manually level the bed with paper its even . When i start a print its not even close like a half inch away . Ready to rip cr touch out and send back. Prints fine with out
Hi. Try clearing settings (resetting the eeprom) and see if that changes anything. Its odd that it goes from the center to the front right, it should go to the front left.
Thank you for this very clear video. I have a creality cr-10 v2 with BLTouch installed. After the autohome, I go to move the Z axis down by .1 increments. However, as soon as I turn the dial (even turning it to have the z axis go up, not down), the nozzle moves down to the bed and tries to bury itself in the bed. After that, the control is fine. Any ideas about what I am doing wrong? I had this printer running well for months - recently have had adhesion issues so I decided to try to recalibrate it. Thanks.
Hi. What board are you running? I don’t have too much experience with the CR-10 but it may be worth erasing your EEPROM and running through the z-offset calibration again.
@@3DPrintscape Thank you for responding. i reset the EEPROM and that fixed the issue.
Great video, I was able to install my bltouch with your help following this video. I am wondering if you can make any modifications to the firmware to make probing faster, I have a warp bed so I need to increase my probing points for more accuracy, I have seen other videos having advanced setting(teaching tech) but he is using Marlin firmware, wonder if you can do the same with TH3D
Hi. Thanks for the feedback, and im glad you got your bltouch working. I honestly haven’t looked into that too much but there may be some options. That said, if I remember correctly it reduces the overall accuracy.
Thanks for the awesome video my printer keeps printing in the air. Before I start the print it the z ofset is correct but then when I auto home or print it still prints in the air. Any tip?
Hi. The z-offset wont impact the autohome. If you do an autohome, the height will match whats in the firmware.
I searched and searched for someone to explain this to me in simple terms. Thank you. great video and well explained. You got a subscriber!
Glad it was helpful!
Hi brilliant video, can I ask where exactly do you run the bed levelling element where it checks the bed in 9 places?
Hi. Thanks for the feedback. I have it running the mesh at the start of each print. You need to add the g29 code to cura to do this. I cover that in more detail in this video th-cam.com/video/Xiy-oLLrB1k/w-d-xo.html .
@@3DPrintscape thanks for the link joined discord grp and understanding it all a little better although I've installed mine via the pin adapter.. 👍
Thanks to your other video I was able to build my own firmware for mine, but it won't let me move the Z axis below zero. is there a range I need to edit on the firmware to allow this or am I missing something else? can I edit the firmware I already made in VS or do I need to build it from scratch? thanks so much! love your videos!
Hi. If your z axis goes down but wont go below 0 you have the software endstops enabled. You can disable them with m211 s0 or in the config by commenting out #define MIN_SOFTWARE_ENDSTOP_Z .
hello
ive been following your videos and just cant seem to get mt CR-Touch to work. the front of the bed lays fine but the back looks like its too low so the fillament doesnt sick to the plate. any ideas?
Hi. Are you running the mesh at the start of the print?
Yea. I just spend whole day with setting bltouch without sucess. And now, at 21:00 this guy just casually say: "Yea i forgot to mention this stuff in last video." And then i learn everything in ten frickin minutes. Great job dude.
Hi. Thanks for the feedback. I hope everything is working for you now.
@@3DPrintscape Yes, thanks to you i had simply awesome day. Keep it up. We noobs need you.
I have an ender 3, i'm unsure if it's the pro or not. I had a few questions, can I keep the creality or default firmware? I'd prefer not to remove the clips, also does this work with a heated bed? It looks like yours has had some glue used on it for adhesion?
Hi. You can keep the Creality firmware if you want, I just not a fan of it and the thermal runaway protection didn’t exist in old versions and is questionable in new ones. I assume that if you are asking about the clips you are using a glass build plate, if that’s the case they should stay. Mine still has the magnetic adhesion material on it (this comes stock with the Ender 3 Pro) but I will be removing it soon.
Hey chap upgraded my board to a 4.2.7 and upgraded screen aswell and firmware adjusted the z offset but it keeps raising it self when starts printing ?
Hi. It sounds like the z offset is not set right, or you have something moving which is messing with the z offset.
@3D Printscape finally got it sorted changed the firmware all good now
hello so thank for all the videos however i cant get the bltouch z offset to go negative for now im back on manual firmware but any help with this issue would be great thanks
Hi. I plan on doing a video on this as soon as i get the hardware to test it. There is a software endstop that needs to be disabled, or the min value needs changed in the firmware. I think this is the case with the Creality firmware (need to verify that). You should be able to disable it with the M211 command. marlinfw.org/docs/gcode/M211.html
I found it. M211 s1 or s0. (Enable or disable software endstops in marlin)
I do not have a setting for Z offset under Motion > Control. Any suggestions for the new versions that don't include this option?
Hi. Can you go to the about screen and let me know what version you are running? It sounds like the bltouch firmware didnt upload.
@@3DPrintscape I managed to find it! It appears in newer versions of Marlin with the BL Touch firmware it has been moved to Bed Leveling > Z Probe Offset
I followed your video step by step but when I store the settings nothing saves it goes back to the way it was every-time before I did the settings is there anything I'm missing???
Hi. Try to do the save with the sd card in the printer.
Great video it fixed all my problems , i really cut not find out how to fix the lose head THANKS A LOT YOUR MY HERO FROM NOW ON
You're welcome!
My extruder is wiggly, but I cannot figure out how to get it to be stable. I don't have a side-screw under/beside the CRTouch like you show here, and I tightened the rollers as much as possible, but I can still move the extruder up about a 1/4" under either top roller. Any ideas?
Hi. There is an eccentric nut on the carriage (typically the top wheel). Tighten that and it should help alot.
@@3DPrintscape Once I figured out what the eccentric nut is, that did it! Thank you!
Hey - interesting video. Can you explain why you set the Z offset at -2.5? you mention that the card was loose at -3.2 and tight at -3 so picking in the middle - but -2.5 is not in the middle of those two numbers. Thanks
Hi. If i remember right, i had to tighten the z-axis. I didnt think it would make a difference for the video though.
I've done all of these steps. My problem is the settings are not saving. I'm having to reset the z offset after every print, and for every start up. What do I do?
Hi. Im thinking something may be up with your EEPROM. What happens when you hit save settings? Also, do you have an SD card in when doing it? If not, try to put one it.
@@3DPrintscape printer beeps, and I've done it both with and without SD.
The beep is normal. If the eeprom doesnt work and there is an sd card in the printer it should save to that and pull from it if its in the printer on next load. @@christopherzieske7854
Do you have an updated video for BL touch with marlin. I have the quit board and bltouch I have spent 2-weeks trying to get it to work and trying to find the right software. Unfortunately I just hooked up my z-axis agian
Hi. Kinda, i have i split between two videos th-cam.com/video/Xiy-oLLrB1k/w-d-xo.html & th-cam.com/video/pQ7WZST8sqk/w-d-xo.html . There is also a full walkthrough for the skr mini that will give you most of the specific bltouch info th-cam.com/video/PMG4bC9I3DA/w-d-xo.html .
I don't seem to have a selection in my menu for setting the z-offset. I have the probe offset. Is that the same?
Hi. Ya the probe offset is the same thing. They just changed the name between the tft firmware version.
New to 3D printing so thanks for this. I have an issue where even with my Z offset maxed out it’s still way too high off the board so I can’t use the paper thickness trick. Any idea what the solution is…?
Hi. What do you mean when you say you have it maxed out, whats the actual value you have it set to?
@@3DPrintscape scrolled up to 4.9 I think - doesn’t go any further
@@gordonking9682 The offset should be negative, something is off. Is the probe below the nozzle?
Anyone know went the cr touch different take the z offset negative value even if it's stored?
Hi. Is it letting you set it negative, then goes back to zero? You may have to disable the software endstops with the m211 command.
I have a cr touch and noticed that your instructions are a little different here than on your cr touch video. Mr extruder is a little high. Can these steps in this video be used to make correction?
Hi. Ya, adjusting the z offset should be able to fix that.
I installed a car touch on my Ender 3 4.2.7 silent board and dual z stepper motors and every time I do the 9 point level my z offset changes even after storing my offset settings any ideas why this is
Hi. How much is it changing, a lot or just a little? Do you have any excessive movement on any axis or the hotend?
Hi there. Great video. I am following word for word. My Z probe offset is set so I am getting drag on the paper but when I set a print away it is still printing in mid air as if it is not taking in to account z probe offset input. I have stored settings etc too so not that? Do you have any idea of problem? Thanks
Hi. It sounds like the z-offset still isn’t set correctly, did you account for the initial value (I think its +5) when coming up with the final value? You could try to kick off a test print and lower the z-offset while its printing until the filament is sticking correctly. If you go that route, make sure you save it afterwards.
@@3DPrintscape Hi thanks for the reply yes I account for that. It was +10 on my printer. Any idea how I would do a test print on my purse i3 pro b.
I was able to adjust the z offset height during printing a couple days and and now it just seems like it is not taking the offset setting into account at all and also it will not adjust during a print...
@@ScottAndJen If its set right and not actually utilizing the setting, I would try to erase your EEPROM. Just make sure you make a note of the setting you still want so you can put them back in afterward.
@@3DPrintscape Thanks for this. How do you go about erasing EEPROM. Saving the setting is no problem I can simply follow your video again.
@@ScottAndJen It depends on the firmware you are running. But generally its "erase settings" or "erase eeprom" under the configuration menu.
My bltouch came with the solid one piece connector that connects into the dedicated port on the skr mini e3 v2. So I left my z endstop switch plugged in but no one has a tutorial or video on how to setup the bltouch with the zstop still plugged in. How do I setup the probe with the zstop?
Hi. Comment out #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN and uncomment #define USE_PROBE_FOR_Z_HOMING in the firmware.
@@3DPrintscape after changing the firmware should I get rid of the zstop switch and unplug it or should I leave it in place and just adjust it down a little bit so it is simply there as a failsafe
@@seth1530 The firmware is expecting it to be there, so you should leave it.
Hey sorry just wondering if you know why my Z-axis wont auto home after installing the touch? I've yet to update my Marlin for it, but I figured I'd try to auto home after installing it and for some reason it just stays where it was at 0.00 Z. Is it just cause I unplugged the Z when it was placed there instead of at home? And any idea if updating my FW would help or should I put the Z axis back and then redo it all? :
Hi. A lot of connection changes happen when you install the BLtouch, so it doesn’t surprise me that things don’t work correctly on the existing firmware. Honestly, I would just try to update the firmware next to see if the auto home gets fixed.
Hi 3D Printscape, when I do an auto home on my Ender 3 pro none of the end stops work the x,y,z just sit there making a noise until i turn it off and on again. Thanks
Hi. Did it work before and just start doing that and did you change the firmware at all?
@@3DPrintscape no and I swapped the board out for the V4.2.2 and it is now working
hi, i have the same board and bltouch, the issue that i am having is when trying to do set my z offset, once z is homed, it moves up to 12mm, so then move the z axis down once it hits 0.00 it will not go negative, i have reflashed btt firmware several times and still the same results.
Hi. Are you doing a home on the Z axis or just the standard auto home? I noticed that I had to do the auto home before it would let me go negative.
@@3DPrintscape yea, I had done both and still wouldn't go neg. So I followed your video with using the branch that BTT has for the board, and it worked, now other issues have crept up, like.. while printing the CHEP Cube, it will just stop and extrude loads of filament in a straight line, then continue printing and no extrude
That seems really odd, I haven’t seen that behavior before. If you send me a copy of the gcode I will try to print it on my printer. My email is admin@3dprintscape.com .
i know this is an older video, but have you ever seen an issue where the z axis doesn't change no matter what value you're putting into the z-offset? for some reason its not accounting for the z-offset when i try to zero the z-axis
Hi. Doe the auto home and mesh run correctly?
I set up the skr mini 3 v2, bl touch exactly how you did and did the bl touch homing z .bin and flashed the printer but I do not have the same options on my printer I don’t have prepare or control and when I try to set the z probe offset it does nothing it will not get the nozzle closer to the bed btw I am new to printing
Hi. Did you end up doing the TFT35 as well? If you did, there is a nice wizard that does most of the work for you. If not, i need to know more about the firmware you used and what behavior you are seeing.
hi! Im having an issue moving my z axis past 0, I'm using an ASK board and BL touch on an ender 3 pro
Hi. It sounds like software endstops are enabled. If you built the firmware, you can disable them there or you cna send the m211 s0 command to the printer.
@@3DPrintscape Thanks!!
what if one corner is higher or lower than the point where the nozzle is in the video while you are adjusting the knob? how this can be accurate? Thank you!
Hi. The software stops should account for that. The printer only goes down to the mechanical stop when its homed. It is possible to manually run the nozzle into the build plate, but you can do that with the stock plate as well. I have always just gone about 1mm lower than the top of the build plate, this has worked out well for me. You cant have it even with the build plate because you don’t want the mechanical stop to be engaged when printing the first layer. Hopefully this helps.
I have an ender 3 pro SKR mini2 with a newly installed BL touch per your video @3dprintscape. I'm using the standard BIGTREETECH-SKR-mini-E3/firmware/V2.0/firmware-bltouch-for-z-homing.bin firmware off of github but when I flash the SD, insert and try to autohome my printer just drills into my z endstop instead of homeing to center. Any suggestions? (also posted on your discord)
Hi. I replied in discord, but it sounds like it may be a wiring issue.
I made the adjustments easily and my z axis moves using the controls or while homing. When I begin a print the z axis does not move up throughout the print and if I go to move it in the controls it reads NaN. Any idea how to fix this?
Hi. It could be related to the bltouch wiring, or the wiring not matching the firmware being used. Make sure the wiring is correct based on the actual pinouts.
When trying to set up my CR touch on my ender 5 Pro, I have disconnected the z stops, as per instructions. This is causing the printer to auto home and try to crush the nozzle through the glass bed. Can you please help
Hi. Connect the z stop switch back up. There was only only creality firmware build i have come across that required it to be disconnected.
Mine won't allow a postive z axis adjustment. I auto home, auto level and everything is just fine. I go to print and it acts like it is looking for the Z stop, and obviously there isn't one, so the head smashes into the bed until it can't move any lower. Then I end up turning off the printer. Nothing has changed since the last time I was able to actually print. For over a week the BLtouch worked well. Now This. Any ideas?
Hi. This is a pretty common issues if the wiring doesnt match the firmware. Are you using prebuilt or firmware or did you build your own? If you dont have the z-stop plugged in, the probe stop should be connected where the z-stop.
Another great video. however I find myself having to adjust my axis on every print. Any fixes?
Hi. Thanks for the feedback. What axis are you having to change on every print, is it the Z one?
@@3DPrintscape yessir. the z axis consistenly defaults back to +5. I have followed both this video and the previous one covering the BLTouch. I'm thinking it has to be an issue with the code on my end.
@@3DPrintscape Additionally, my extruder starts to print off the bed whenever I do manage to start printing (Which usually requires me to manually move my extruder during the heating phase) it typically starts off the front left corner of the print bed
your video on the bltouch helped me a lot, now I'm here trying to set the offset, but when i got to Move Z mines does not go past "+0.00" it wont go negative therefore I cant level the bed manually to se the offset
Hi. That behavior is odd, every machine I have worked with has let me go into a negative offset. So its just stopping when you get to 0? At that point, were you able to move it back up to a positive number? I have seen the system get stuck before, and just trying to see if that’s the case here.
Its was a firmware issue, I have the neggatives values now, but even with that plus re watching the video, i still cant get a proper aligment to the nozzle for a good first layer
3D Printscape I am also having an issue with the auto leveling. For my ender 3. My print head is too far away for some reason. Even though the bed it at top height.
Hi. It still sounds like the z offset isn’t set right. One thing you can try is to start a print then adjust the z offset while its printing. Once you get to the right offset doing it that way, make sure you save it so you don’t have it do it again.
@@RiikanVR hi, how did you correct this? did you just rebuild marlin and not use the preconfig files from btt?
Hi, when I change my z probe offset to -2.9 (after measuring), when I autohome, it adds 2.9 to the 10 (default z level) so it sets it to 12.9. Idk what is going on, but am I doing something wrong?
Hi. Something sounds off. The autohome should stay at 10 and the offset comes into play when printing. I would try to clear setting and run through the process again.
when i auto home my printer it does x, and y just fine but when it goes back to the center to home the Z it will go up and then not extend the probe instead tells me STOPPED. i have a 4.2.2 board and have been trying different softwares from the net but does the same thing every time please help if possible.
Hi. Can you join the discord server or email me pictures of the wiring? My email is admin@3dprintscape.com
I added a bl touch to the ender 3 and updated the firmware but when i try yo go negative for the Z offset it doesnt give me an option. It stops a 0. but if i go into configuration i can change it to a negative value. Any idea why?
Hi. Ya thats related to the software endstops not allowing you to go negative. This can be turned off when you build the firmware or afterwards with the M211 S0 gcode command. marlinfw.org/docs/gcode/M211.html
@@3DPrintscape thank you for your help. I will add the firmware I got from the site you put 10$ a year for so I don’t think it’s editable and I don’t know how to add that code. Is that in cura? Thank you for your fast response and help!
@@SCurryjr32 You would use a tool like Pronterface to send the command once the printer is connected to the computer.
Hi when i auto home the extruder doesnt go down on the z axis it moves to centre then stops and i get a message on the info screen saying Home Z first. I am using an Ender 3 pro. Do you know what may be wrong?
Hi. Is your z stop connected?
@@3DPrintscape it’s is not I installed an auto leveller which had a red plug with black and white wires which went where the z stop was
@@tomandrew5917 Ok, you need to make sure you are using the z homing firmware if its wired that way. I have some builds on my site for it, but i dont think any of the creality builds will work.
My offset was set to -2.1 initially and was printing great until I changed the nozzle. After I did that it was too high. Using your calibration, it changed it to -1 which’s seems like that’s making the nozzle higher.
Hi. You are correct in stating that -1 is going to be higher than -2.1. Can you run through the calibration again? If its home position was at 5 and you ended at -1, your offset would be -6.
On the right side of my z axis the actual z axis is able to move up and down easily, should I tighten it?
Hi. Yes you should tighten it.
My bill touch will auto home, but when it finishes auto homing, it stays up instead of going back down to zero. When it stays up, it says that zero. What do I do?
Hi. That sounds normal, +10 is where it finishes the auto home. You need to set your z offset.
I followed your instructions to the T got motherboard 4.2.2. The problem I have is I have to do an auto bed leveling every single time before a print otherwise my printhead tries to bury itself in the bed, I ended up with three holes in my bed before I figure that out. why is it doing that.
This thing seems like more of a headache and it's worth.
Hi. I run the g29 command at the start of each print to make sure i get new readings but its not necessary. Run the bed level then make sure to save the settings. It sounds like the settings are not being saved or something is moving around, may be the extruder carriage?
Just installed the BL Touch with a V4 2.7 board on an Ender 3 but the S axis won’t move down. Any help or ideas would be kindly appreciated. Thanks
Hi. It sounds like a firmware or wiring issue. If your using the creality firmware, make sure you have the z-stop connected still, then make sure the 5 wires for the bltouch are connected and in the right order.
I'm having this problem every time I do exactly what you said in the video My nozzle is still too high when I print it's like it won't save my settings. HELP!!
It sounds like it's not taking the z offset. Are you sure its being set right?
Thanks for the reply but I fixed it. Cura has a Z-offset plug-in that fixed all my headaches!
@@billnavarre5308 Cool, im glad you got it working.
when i hit the first auto home, the nozzle is always pressed to the bed so I have to move it up into positive numbers, and then when i print it doesnt touch the bed, im new to this and im having such a bad time
Hi. It sounds like the bltouch isn’t getting engaged. Can you confirm that when extended, the probe on the bltouch extends beyond the nozzle on the extruder?
I have a 4.2.7 board with The firmware downloaded from the Creality website. Ender-3 Pro- Marlin2.0.1 - V1.1.2 - BLTouch - TMC2225.bin
My Auto Home Z-axis defaults to +10 which is too much to compensate for with a Z Probe offset. How do I change the default of the Autohome?
Hi. The firmware by default is set to +10 but that can be accounted for with the z-offset. You will want to home the printer, then lower the z axis until it gets to the proper height. That value will then be your z-offset.
@@3DPrintscape Thank you for the response. So I go to prepare/move axis/and then lower it. Do I then store the setting or something to lock it in? After I lower the Z axis it is reset back to 10 every time I home again.If you are referring to the Probe Z-offset, the max it will go to is -9.900 and that is still way off the bed.

Hi, I have the CR Touch and I'm finding that test squares at the back are showing signs that they are a little too far away from the bed. However all other squares are perfect, when looking through a magnifier. Any suggestions welcome.
Hi. Is the mesh that gets created hitting around that area?
@@3DPrintscape @3D Printscape it's doing the 9 stage process as expected covering the bed surface, but when the squares are viewed through a magnifier, the beading doesn't quite meet leaving a slight gap between the lines that makes up the base of the square. All other squares from the centre to the front are perfect and join leaving a perfect surface. Maybe I'm being too picky, but I didn't know if there was something I could dial in to compensate.
I'll print the test again and attach pics

@@brumpsstuff8088 Gotcha, i think there are two options. Option one would be to try to increase the grid size (maybe 5x5) to see if that helps. Option two would be to get a board with better drivers that can make smaller adjusmtens.
@@3DPrintscape thanks for replying. When you mean increase the grid size 5x5 is that something I have to apply within the Marlin firmware? I could give that a try but that'll mean it will probe the bed 25 times. It would be interesting as a test.
my bl touch goes to the center of the plate with x and y axis perfectly but the z axis doesn't move when the bl touch pushes out the probe. Instead it just sits in the center 20mm up and moves the probe in and out. Any idea what's going on? Please help. If I touch the probe when it's moving it starts going down then stops. (I have board 4.2.7)
Hi. It sounds like the black and white wire is reversed or the wiring doesnt match the firmware you are using.
Hey man I'm having trouble with my printer it's an ender 3 pro I have installed it perfectly and when I tried to bed level my extruder crashed into my print bed and so I turned it off but now my stepper motor won't go down, the info screen now says endstops z please help
It also says home z first
Hi. You should auto home before trying to make any adjustments. How is the bltouch wired and are you using precompiled firmware or a build you made?
does the firmware automatically work with a sprite? just change the e steps?
Hi. Yes, just make sure you set your e-steps.
I have been trying for ages to get the new CR touch installed on my ender 3 pro. I finally decided that I needed different firmware. After strugging with the directions to compile the firmware from Marlin I found someone who was selling compiled firmware. Only now my z-axis won't move at all. When I home it it moves x and y but fails when it tries to move z. I'm at 11 in terms of frustration and could really use some help.
Hi. Are you able to join my discord server (invite is in the video description), it will be easier to try to troubleshoot things there.
How do you level the corners of the bed when you have the bltouch installed?
Hi, It depends on what mainboard and screen you are using. If you are using the stock one, you will want to lower the z-axis to the point that its almost touching at one corner, disable the steppers, then move it around to all the corners making adjustments as needed. After that is done, you will need to adjust your z-offset again.
@@3DPrintscape ok thank you. And yes I'm using the stock ones. Also, when I print something like a 20mm calibration cube that my X-axis value is 20mm, but my Y-axis is like 19.8mm and my z-axis is about 19.74mm or so. Could my steps/mm be off on my Y and Z motors but be good on my X?
It possible your steps are off, I would start there.
Mine is still way to high, and when I go into the move axis, Z axis, option, I can only go do to 0.00, which leaves my extruder about 5mm too high. I can't get into the negative numbers like yours. Needed to disable software endstops. M211 s0
Hi. Ya you would need to disable to software endstops in some firmware. Sorry, I should have been more clear about that.
My printer still prints way too high and also seems to go up when making a straight line.
I set the z-offset correctly and stored the settings so I don’t know why it still does this
Hi. It could be a bad mesh or the z offset isnt right.
I see you're changing the z offset with a 0.01 tolerance.
My Ender 3 pro only have 0.1mm tolerance and I can't get it right, this is too much.
What fw are you using for this? What can I change to fix this?
Hi. Im using a somewhat recent build of Marlin. I actually have it available to download from my site if your interest. 3dprintscape.com/marlin-firmware-builds/
What version of Marlin is this please. I followed your guide on the SKR Mini E3 v2.0 install (fantastic, thank you), but on using the bltouch for z homing file I a) dont see that wheel for z offset b) cannot seem to take z offset negative. Can you please point me in the right direction?
Hi. Im currently on November build of Marlin 2.0.6.1. I did notice that if im not using the wizard from the tft35 that I had to autohome the printer before I was able to get to a negative number.
3D Printscape I think I am on the same install but offset home doesn’t seem to allow it even, I have to do a bit of hit and miss with it.
I checked and actually I’m on 2.0.7.2
I’m having the same issues how can I fix this I’ve been at this for hours now.
@@bosslady_fpv5515 oddly I managed to get it moving to negative z the other day for about 30 mins, but no idea how to replicate it so I am back to where I was. I think I did something with the “set home offsets” in advanced.
For now I am just using a huge negative offset in configuration at first, then moving the z to the correct point with a offset, and combining them again in configuration. It’s not ideal but it works.
I got my bltouch on. I'm not sure the software is right though. It will go up but not down and the little toothpick thing isn't coming out. Any advice?
Hi. How do you have the bltouch wired and did you use the precompiled firmware?
I’m going bald here after two days of troubleshooting...
I have done the firmware upgrade from your tutorial and followed this tutorial, but when I start to print something it starts about 7 centimeters up in the air. And when I “Auto Home” it raises about 10mm each time.
My setup:
Ender 3 Pro
BLTouch (Antclabs 3.1)
4.2.7 board (upgrade)
The original z-stop cable is disconnected completely and the z-cable from the BLTouch is connected to the dedicated BLTouch connector on the board. Not to the original z-stop connector.
Please help😭
Hi. The autohome being at +10 makes sense, and is normal. If the printer starts printing mid air, then the z-offset is not set right. I would need to know what firmware you are using but if your not on the Marlin bug fix line, i would recommend going to that and enabling the z-offset wizard. Here are two videos to help. If you run into issues, you can join our discord server and I can try to help you more there. th-cam.com/video/pQ7WZST8sqk/w-d-xo.html & th-cam.com/video/2gRfU26aTDs/w-d-xo.html Discord: discord.gg/Bu94EYVkrU
If my offset is +1.3 is that bad? Considering yours was a negative to set the offset?
Hi. I've seen pretty large ranges on the z offset used by people, so I don’t think your being a positive number is bad, assuming everything is working properly.
I have set up my BLTOUCH on my Ender 3 Pro v1 with 2.4.4 board but when I do an auto home the Z goes up and then the print crashes and I have to power cycle. I have installed the latest Malin firmward with BLTOUCH
Hi. It sounds like the z-axis stepper motor direction is flipped. Here is what I have mine set to.
// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR true
#define INVERT_Y_DIR true
#define INVERT_Z_DIR false
I have marlin 2.0.5.3 on the ender 3 and it does not allow my Z move to go below 0. so i cannot set it before the print, I can only use tune/Bed Z after the print has started, which can be a pain in the ass as it is hard to see if I have enough squish whilst it is printing (especially on small prints)
Hi. One of my other subscribers had a similar issue and said it ended up being a confirmation in the firmware. Since your running Marlin 2.x, I assume you swapped out the mainboard, or did yours come with the 32bit one? Also, are you using a prebuilt version of the firmware or did you compile it?
@@3DPrintscape no worries! I found the setting to enable negative values and yes I have an SKR mini E3 :)

Hi. Did you enable it in the firmware? Its disabled by default.
@@3DPrintscape thanks for the reply. Was able to figure it out.
New to 3d printing, so bear with me. I installed a 4.27 board on ender 3 pro, updated firmware, and installed a cr touch plus the firmware. I followed your video to set z offset. On the display there is no place to save offset numbers. What am I doing wrong?
Hi. Can you check to see if you have anything related to bltouch in the menu? If not, the firmware didn’t take.
When my bltouch is auto homing the sensor hits the bed and keeps going with no retraction. All the test and resets work but the home doesn’t. Any ideas other that switching the black and white wire? I’ve all-ready tried that and it wouldn’t work at all when I did. Thanks for the video! Great info and setting it will be a breeze after I get this issue worked out. Thanks again!!!
Hi. Do you have the bltouch connected to the z-stop or bltouch stop port? Also, can you email me a copy of your configuration.h file to review? My email is admin@3dprintscape.com .

@@PastorTFS Are you using a precompiled firmware package or did you compile it yourself? If its precompiled, you wont be able to get it. If you compiled it it would be under the Marlin directory. For example, mine is here. C:\Users\Owner\Desktop\Marlin-2.0.x-SKR-mini-E3-V2.0\Marlin
I dont know about anyone else, but Ive been having mixed results, but I think I got it now.
If you already have a Z-offset set and you want to change it. Maybe you modded your machine or you removed the bed to pull a print, etc.
And your set offset isnt printing correctly.
What I did was change the Z-offset back to 0. turn the machine off and on, home, auto bed level, home again, move Z down to 0, then change Z-offset.
Im running an Aquila X2 with Alex Firmware BLTouch 4x4. Although, I have the CR touch.
Im not totally sure if Im just doing something wrong or if thats the process?
Any suggestions are appreciated.
Hi. That process sounds right assuming you are saving the setting before powering off the printer.
@@3DPrintscape 'sigh', if im understanding this correctly, the reason im having problems is because im not "saving" the setting?
I mean, it saves the bed level mesh, however its always unchecked when I turn on the machine, but the Z-offset is always at what i set it at.
Ive seen there is a "save settings" is that what youre referring to?
I like to bed level and check offset before every print, so im not sure this is a problem.
@@bear5016 You want to save the mesh after you run it the first time. Then from there, you add the G29 command to your machine profile in Cura to kick off the mesh at the beginning of each print.
@3D Printscape No i just run it every print anyways, because i remove the bed and put it in the freezer to remove my prints.
Or are you saying i have to add G29 code or else it wont use the mesh?
@@bear5016 Ya, you have to add the G29 command to your printer profile which tells it to run the mesh at the start of the print.
So I installed a silence board on my ender 3 but I updated it and now the z axis doesn’t go down I really need some help
Hi. Is the z stop connected?
Hi, how's it going! for starters your vids are great and you've helped me a lot by watching your vids. So to break it down I have an Ender 3 Pro with a 32bit board. I also did the MicroSwiss all metal upgrade. I recently the issues starting coming after I added a cr touch to it. I've tried to calibrate the z axis numerous times based off the video on how to set the z axis. after attempting to adjust it i come across these 3 issues. either the extruder will move to the back right corner of the build play raise above the build plate and start extruding filament in a large quantity with even moving around, or it will crash into the build plate and drag across everywhere, or last but not least it will hover too high while attempting to print. I've spent a couple months watching videos and I've had to walk away fir a week or two at a time to maintain my sanity lol. I hope you can assist me . thanks!
Hi. Try to clear you eerpom. If that doesnt work, i would try to pull a fresh copy of the firmware and config example and build it again.
hi sir, why my z axis won't go down further around -3.0 even if i input -10, which is crazy. my motor won't let me. but when i'm printing, the adjustments applies.
Hi. Based on what your describing, i believe its the software endstops. You can comment out #define MIN_SOFTWARE_ENDSTOP_Z or use the m211 command.
@@3DPrintscape hi sir, i'm not much of a programmer myself but i'll be patient learning new stuff. The command/comment you mean is for the print whenever preparing a 3d model in slicer?
@@erysonrodriguez8398 Not exactly. The first option is a setting in the firmware that can be commented out but only works if you are building your firmware. The second one requires you to connect your printer to your computer and using something like Pronterface .

no matter how many times i try my nozzle keeps jamming into the bed. I've set the z offset and reset it at least 20 times, still continues to jam into the bed. Any help?
Hi. Sorry to hear you are having issues. Try starting a print, and after it finishes the self-leveling phase raise the z-offset to a point that you know it wont touch the build plate. Once the printer actually starts printing, start lowering the print head until you see the filament start sticking to the build plate evenly. Once you are there, make sure you save the setting so that it stays through power cycles. If you still have issues, you can email me at admin@3dprintscape.com.
And move it from CONTROL menu. I guess prepare wont show
This is killing me. When I auto home it goes to the middle but then as it starts the process it does one test then blinks red continously and won't allow me to change the z axis like in your video. Any suggestions?
Hi. How is the bltouch wired and what firmware are you using?
I have the 3 v2 (4.2.2 motherboard) with Marlin 2.0.1 installed. When I go to move the Z axis it wont let me go below 0. What am I doing wrong?
Hi. I think that’s related to the software endstops. I am waiting on another bltouch to come so I can do a video covering it. I just created a discord server, so I can try to provide more assistance over chat there if your interested. discord.gg/Bu94EYVkrU
i always measure the two sides of the gantry, level them manually with steppers disabled. (takes 3-5 measures and adjustments) then i auto home. I find that the two motors never align perfect after a powercycle. its not much deviation but 0.1- 0.15 from right to left side makes a poor firstlayer and not good prints.
I tried synching the two rods with a belt ontop but it still happens after every powercycle.
Also when you plave something on the plate your hand applies a slight pressure that affects your leveling. since you have a bltouch just make a matrix of your plate once, put locktite on the adjustment screws and live your life :)
Hi. I moved to solid rubber mounts and it helped out a lot.
@@3DPrintscape same. I also am thinking of bolting the frame to a heavy sturdy table. The solid mounts did wonders for the ringing
@@reyalPRON Interesting thought. If you do that make sure to put some foam or something between the table and printer. It will help level things out more.
@@3DPrintscape would that not counter the stiffening? I was thinking hard mount like the big machines at work are bolted to the floor.
Something like the insolation foam pads you can get at home depot are pretty hard but will help keep the printer level and reduce some noise. @@reyalPRON

I recently set up my printer and updated the firmware to work with the BL touch 32 bit board on my v3 pro.

Hi. In sounds like the z offset still isnt right. Keep in mind that it doesnt come into play until the print starts, so if you autohome the printer it will go to +10 by default regardless of the z offset value.

Does your bed need to be level before doing the z offset?
Hi. Technically no. The z offset is measure from that one point so the bed not being level should affect this value.
