CR Touch With Marlin Firmware
ฝัง
- เผยแพร่เมื่อ 23 พ.ย. 2021
- Last week I showed you guys how to install the CR Touch on your Creality printer using Creality’s firmware. This week I’m showing you how to build the latest Marlin bug fix release to work with the CR Touch. This video is only meant to cover the firmware portion of the install, so I recommend starting with building the firmware. Then moving over to the other video, • CR Touch Install Guide... , to cover the rest of the CR Touch install.
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

You are a saint to share your knowledge in such a thorough and well-paced way. Amazing teaching skills. Thank you!
Hi. Thanks for the positive feedback :).
OOOOOOooooh Man, I gotta say, I hardly ever comment on youtube videos. But you sir are my hero. You made updating, and explaining how to do this possible. I'm blown away how awesome this is. Well done!
Hi. Thanks for the feedback :). I'm glad I was able to help out.
Agreed entirely this was very difficult to do without this guy
Hi i,m trying but it says incomplete everytime i have a crtouch and the skt mini e3 v2.0
Appreciate all the help the videos you put out have provided me. I first tried setting up the CR Touch and had so many issues with it so eventually boxed it back up. Got it back out on the printer and after a couple videos I finally got the CR touch working flawlessly. Haven't seen my printer, print this well ever. Really appreciate all the help.
Glad to help
This tutorial is too good, I come back to it every time I gotta do firmware stuff. Tryna set up MBL on a crappy old 3D printer at work right now and this tutorial is BLESSED
Hi. Thanks for the feedback :)
Thank you for making this! I have very limited coding experience and was at a complete loss when setting up my CRTouch. Your video was a lifesaver!!
Glad it helped!
Thank you so much! I fought with this thing for about 10 hours and the use probe for z homing was not mentioned in 10 different videos I've come across! i learned a lot in that time frame but boy was that frustrating watching my printer crash. Thanks again
Hi. Thanks for the feedback an i hope you got everything working now :).
All I can say is THANK YOU! You're a lifesaver. My printer was acting all kinds of crazy after installing CR Touch and flashing the stock Creality CR touch firmware. This fixed everything!
Glad i could help :).
You have earned a sub and comment by someone who does not comment often. You have fixed my 3D printing problems (Freezing and not reading SD card). I only had this printer for 2 weeks and after installing the CR Touch and experiencing all those issues, I was about to be done with it. I cannot thank you enough.
Hi. Thanks for the sub :). Im glad i was able to help out.
Perfect, completely fixed my printer. My screen and printer froze while printing the first layer. Doing this has brought it back to life and working perfectly. Thanks
You're welcome!
In addition to your suggestions (thanks again), I also modified the _Bootscreen.h file. The first time I did it was pure vanity; to add my initials to the splash screen. But then I saw it when the printer powered on and saw that it was the fastest way to confirm that the flash took.
There is a constant variable called "custom_start_bmp"; where bmp presumably stands for bitmap. If you look at it in the right way, you can see the ender logo comprised of 0s in a see of 1s. That logo appears in the upper right of the VSCode workspace. To make my modifications, I replaced 1's with 0's in the second column from the right (the far right column didn't appear on my printer.)
It may be redundant, but I am tempted to add a version number after my initials.
Hi. I have made some changes to the _bootscreen.h file before as well. You can actually do a decent bit with it, including adding multiple screens and adjusting how long they stay up for.
Thank you so much. After getting frustrated with the first cr touch I had I ended up returning it. Ordered another one and was determined to get this one to work and thanks to you I was successful. Many thanks!
You're welcome
Total lifesaver. My printer was pretty much bricked until I went through the steps you laid out. Thank you.
You're welcome!
8:25 For the CR Touch on an Ender 3 V2 with the included metal bracket, I measured - 46 and - 8.
Thanks for sharing.
Thanks

What about the "Z_Min_Probe_Pin"? Does this need to be set?
@@motorexp If your building with the right board config as your starting point, you don't need to set this. It will default back to the default pin for that board, which is what you want most of the time.
After the changing the settings as you told and uploading the firmware all the X, Y and Z axes are only going positive values. Not even able to set negative values from the LCD. Please suggest any changes required to overcome this issue. I have reset the EEPROM after uploading the firmware. Hope you reply soon.
@@saranisntnice Hi. You can comment out //#define MIN_SOFTWARE_ENDSTOP_Z in the firmware or send m211 s0 gcode to the printer.
@@3DPrintscape Great 👍🏻. It's worked. Thank you so much.
I'm right there with everyone else. I have been fighting with this for the past day and a half and after going through rabbit hole after rabbit hole, I finally found this video. I was honestly about to give up on it and switch back to the stock board. You sir have saved my sanity. THANK YOU!!!!!!!!!!
Hi. Thanks for the feedback, i appreciate it :).
Thanks for this! I flashed the stock firmware yesterday while waiting for this video. Onto Marlin we go!
Glad I could help
Honestly was struggling with a fail to home error - followed your steps and BOOM fixed. Thank you!
Glad it helped!
Thanks to you I was able to build the latest Marlin firmware with CRTouch for my Ender 2 Pro and didn't need to use the premade firmware. I still need to adjust it a bit since my heatbed stops at 70°C.
You're welcome
Oh brother you saved my printer, I was having printer halted issues after installing cr touch, now at least the printer works, still have to level the bed and everything else but is no longer halted. You gained yourself a like, comment and a new subscriber!!!
Hi. Glad i was able to help :)
Saved me £100!! Was going to take it to a repair place, but then I saw this!!!! Thank you, my printer is finally working now!
Glad I could help :)
This is amazing, thought i had bricked my printer and this got it not screaming at me. Thank you for the very detailed video!
You're welcome!
Absolutely fantastic video! For anyone who might find this comment in the future and that it might apply to (small chance, but who knows); I was initially trying to update firmware for a 4.2.2 board on an Ender 3 pro with a BLTouch that was using the Z endstop for 2 pins, and a 3 pin adapter that was given to me by the vendor that sold the BLTouch. To be clear, this was an adapter board that plugged into the LCD screen port on the motherboard, that had 3 extra pins extending off of it where I would plug in the 3 remaining pins of the BLTouch. This would not work, and doesn't seem to have an option in the firmware configuration files to get it to work. In the end, I got a CRTouch that used the normal 5 pin connector on the motherboard, and following this guide to a T worked.
Hi. Thanks for sharing your fix and the feedback.
Holy crap you have no idea how thankful I am for this video! I was about to sell my printer because I was so damn frustrated with it, but you saved me! Thank you so much.
You're welcome!
Me im about to explode mine nothing work
Creality "Plug sd card, plug power cable, power on, and it will update automaticly" right I can play that too... I will become president tomorrow...
Thank you so much!!! I was using stock creality firmware on my ender 3 pro and it wasn't letting me use the full build plate. Now I have unlimited power, thank you for this!!!
You're welcome!
Thank you! I was having so many issues with Creality's default CR touch firmware for the Ender 3, V4.2.2 board. This video made it breeze to update to the latest version of Marlin.
(I was getting corrupted SD cards, and the printer would completely freeze ~1 minute into the print. Updating the firmware solved both of these issues completely.)
You're Welcome
hey im having the same exact problem, do you download the 2.1 bugfix or just the 2.0 bugfix?
@@laloramirez3273 I downloaded the latest release version of Marlin instead of the bugfix version.
@@Nedla How did you go about setting your X and Y offsets when building the firmware? Did you have to manually measure them? I have an Ender 3 Max and cant find documentation anywhere on what to put here.
I am very grateful to you for this video. It is the only one I found so simple, summarized and current. This serves as a start for me to make other types of configurations. Excellent video, greetings from Peru.
Glad it was helpful!
Thank you. I was struggling with this for over a week after adding direct drive. I had to make a few more changes in the firmware but I'm up and running again.
You're welcome!
Thank you so much for all your great videos. You make it so easy to understand everything. So great help to me. Thanks a lot.
You're welcome!
Oh my, you are actually amazing and thank you for this! Been trying to figure out my problems with the most recent release of marlin for my ender 3 on SKR mini E3 v3 (yeah its year old firmware) and i was just about going to cut the wires and hardwire cr touch to Z sensor but you saved me a lot of hassle, thank you very much!
Happy to help!
Dude. Your videos are the best, detailed and easy to follow. Printer is now working flawlessly. Thank you!
Glad to help! :)
Thanks for the video after spending hours getting no where I followed your very simple instructions and even found the correct files for the Neo I can now look at the bed level graph in octoprint as well thanks to the tutorial you did on that thanks again
You're Welcome
Thanks bro. I've been actively looking for a step by step to do an edit to the firmware on my ender 5's. I had updated the hot ends about a year ago and have been keeping my eye open for a solution to get those temperatures up a bit.
I ended up using a stable version versus the bug fix, but for the most part everything went well. That z offset wizard is the best!
I noticed two issues that were solved after doing some research, one was that a manual negative z movement was not possible and that a bed PID tune was not possible.
As I said, there were some adjustments that were made to fix these issues.
I kind of liked how the CR touch did a 16 point level versus the 9 point level, but with a glass bed, it's really not necessary.
Thanks for your help!
Hi. Thanks for the feedback and you're welcome.
This video filled in a lot of gaps left by other tutorials, great video.
Hi. Thanks for the feedback.
Think this is my first ever TH-cam comment - I'm about a month into 3D Printing, picked up a CR Touch Yesterday and have been flashing and re-flashing the correct Creality firmware for my board to no avail. I was literally about to take it(CR Touch) off and go back to manual levelling then I followed this video and boom, there's a benchy printing off as we speak. Many thanks for the clear and straightforward instructional video/fix for me Rob!
Hi. Thanks for the feedback, im glad i was able to help :).
Great videos, informative, to the point, and easy to follow, thank you!
You are welcome!
You literally just fixed my newly upgraded Ender 3 Pro! I installed a 4.2.7 board, and my CR touch went bye-bye, along with my -z movement. I was able to figure out which files to use for my board, make changes, and it's WORKING! W00t!
Glad to help :)
@@3DPrintscape Oi... I spoke too soon? I set the offset values for the Cr touch to my measured values of -43 and -7. However, when I go to auto-level, the CR touch is hanging off the bed on the left, meaning it would completely crush my print surface. Any idea what's going on? This is an upgraded 4.2.7 motherboard, and I used the 4.2.7 config file. Everything I've found SHOULD have fixed this, but it hasn't. Advice?
@@destinibaldonado1390 Try to clear the eeprom. I had a similar issue and that fixed it.
Perfect upload! Thanks for sharing 👍🏾
Thanks for watching
This is great. Very easy to follow and get things working!
Glad it helped!
HUGE THANKS! My CR-Touch went down no mm when leveling or homing with the working BL-Touch Marlin, this worked and fixed it, thanks a lot :)
You're welcome!
thank you so much! i finally got marlin to build and work!
Glad I could help!
Great video and instructions. I recently applied your instruction to the most recent bug fix 21 Feb 22. The initial test run after the edits failed, failure related to "manual probe" line 1079 #define MANUAL_PROBE, changed to #define BLTOUCH. Test build successful!
Thanks again for the great insight.
Hi. Thanks for the feedback. If your running anything like the bltouch, (so a clone or a cr touch) you need to enable that in the firmware.
i love you its 7:52 am and ive been up getting my cr touch to function and this video finally helped.
Hi. Thanks for the feedback, im glad i was able to help :).
great vid, just downloaded marlins software and config files and installed with marlins autobuild and PIO.. then i found this, compiled a build with your vid after going over the congiuration.h changes - so much easier when i dont have to research all the steps - cos youve done all the hard work which i just copied! thanks for sharing
just wnanted to point out though, BLtouch is electromagnet, CRtouch is optical sensor - not sure if that makes a difference to how its set up on configuration.h
oh, another thing, if you check your vid at 10:58 -10:59 youll see a bunch of yellow text regarding DRIVER_TYPE, do we just ignore that?
Hi. Thanks for the feedback. Your right, the sensors work differently but the signal sent back to the board is the same, so the config is the same for them. The yellow warning is more of a reminder to check your drivers. The 4.2.2 ships with the normal and silent drivers. The firmware assumes you have the normal drivers but its telling you to verify there.
Just bought a Ender 3 Pro with a 4.2.2 motherboard, added a glass bed, then a CR touch, and the Creality files online were useless that are the latest and greatest online. My display was wonky, memory card would barely read, Ender froze during prints, and it would not level with the CR properly (Z-axis issues). Then I found this video and my nightmare ended.
THANK YOU
Hi, Thanks for the feedback and im glad i was able to help.
Thank you. This worked perfectly for me on an Ender 5 pro
You're welcome!
@Declan Swords when install cr touch, do you need unplug Z limit connector on board?thank
@@khoinguyen1963 The instructions say to remove it but I have hear mixed results from people on this. I removed it and it worked fine, I have had others tell me it had an error until they plugged it back in. Its possible they updated the firmware, and not their instructions. I would try to leave it plugged in.
90% of videos are real bad, you my friend are in the 10% that are really good and informative. Thank you for this video. Like others I rarely comment on videos unless they are outstanding.
I appreciate that!
great videos thank you so much for putting this together!
Glad you enjoyed it!
To all Windows 11 users, the search is VS works differently then what shows in the video. I could find what I was looking for just couldn't make it take me to it in the code block. Also if looking for things by scrolling everything in the video is approx 150 to 200 lines lower in the code. I was able to work through the differences and get the Marlin firmware installed and now my CR Touch works as intended. Thank you so so so much for sharing this video.
Hi. The line numbers will change based on updates to the config examples which is why i didn't say got to specific lines. I didnt notice the search function changing when i went from Windows 10 to 11. Hitting ctrl+f while your courses is in the text field should bring up the search box.
Worked perfectly! Thank you Rob!
Great, you're welcome
Great video! Very HELPFUL! Good Job!
Thanks, im glad it was helpful.
HUGE SHoutout to you my man, this got me up and running! Seriously! Life saver!
Hi. Glad to help :)
Exactly what I was looking for!!!
Thanks for the feedback :)
This really helped me a lot thanks so much!
Glad it helped!
Thank you so much for the help!
You bet!
Very helpful video. A couple of comments. Can you add a note as to how you "search" within the different sections of Visual Studio - I managed to find the sections to amend manually but it would have been quicker doing it your way via the "search" function. Also how do you find the X and Y offset figures to put in the relevant entry in the firmware for a Ender 3 v1 (with 32 bit board). I used your figures as I couldn't find a definitive answer on the net for this.
Hi. Thanks for the feedback, i will try to work on that. For the x and y offsets. Its the distance from the nozzle to the probe on those axes. I cover it in more detail in a couple of my videos.
Hugely helpful!!! Thank you!!
You're welcome!
THANK YOU! THANK YOU! THANK YOU! Excellent video!
You're welcome!
The video is unbelievably informative and thank you for all the info you continue to put out. I for the life of me keep running in to issues with error codes....is there anyway someone can follow along and just send me the file. Just installed the CR Touch and been pulling my hair out for a day and half now.
keep getting "X Comments are not permitted in JSON"
Hi. I have firmware that you can download here. 3dprintscape.com/marlin-firmware-builds/
This is great, thank you.
You're Welcome
Most TH-cam authors can be rather long winded. However I come across this GREAT posting and could use just a little more detail with the coding. Any chance you could post another longer video explaining some of the commands you've activated? It's been literally decades since I've done any coding and trying to wrap my brain around the coding documentation doesn't leave me much confidence in what I'm doing at the moment. Otherwise excellent job. I really enjoy and appreciate your other postings for being concise and to the point. Nothing worse than sitting through a 20min video for a 30 second answer.
Hi. Thanks for the feedback. I will add something to my backlog for this.
Thank you so much for this! You get a subscribe for your efforts
Welcome!
Thanks! very easy to follow
You're Welcome
thank you so, my 3d printer has the wrong frimware and this is
exactly what i need to fix it.
You’re welcome.
first off thank you for the explanation and your time.
I followed the video get Marlin to flash on the MB See the changes under printer info :) Great
CR Touch lights up probe push out
When i try to auto home it starts to lower but one it Probe hits the bed it retracts but the Z axis continues to go down making a horrible grinding noise.
I have tried increasing the z level then trying to auto home it as it goes down i hit the stock z switch and press the probe which makes the llight turn red but it continues to move down and does not stop
Hi. To confirm, you have both the z stop and crtouch connected right? Is it autohoming in the middle or front left and is this a custom or prebuilt firmware?
Hey @@3DPrintscape thanks for answering, I went back and rewatched your video. Seems that the Marlin website changed up a bit from the time you did the video. I didn't realize but i downloaded Marlin Patched Source instead of the Marlin "Nightly" Source zip. I would get 4 options in visual studio but i tried the one that most resembles your screen.
Reflashed the firmware with the options you suggested on this video and loaded CHEP profile in CURA, since then i have had no issues and printing has really just become slice and print.
Thank you for your videos and taking the time to answer these question in comments.
Def got my subscribe and thumbs up, also recommend you videos in all my groups im in. great stuff man.
Im glad you got it working and thanks for the support @@erickdeleon4959
Awesome video!!
Thanks!
Great video. Why would someone want to leave the z-axis stop switch in place? What are the advantages and disadvantages?
Hi. I know some people still like to home their printer with that, vs the probe. Also, if setup right, its basically an insurance policy incase the probe fails.
Thank you so much!
You're welcome!
Hi and thanks for this video it is very well done and one of the few if not only one I have been able to find regarding installing the new cr touch with marlin firmware! I followed both your videos to a "T" have tried everything and cant get the crtouch working yet on my cr10s printer. I have the v2.1 board that does not have the 5 wire connector so I had to wire it several times using z minus and d11 pinouts because wiring diagrams differ so much its been trial and error and is just really pathetic! I have the creality bltouch firmware installed now because there is no hex file available for the cr touch and I cant get my sd card reader on my control box to read the only available .bin file but even if there was i cannot use the creality firmware at the end of the day because of my upgraded heated bed and all metal hot end is not supported in the creality firmware for high temperatures that I need! by putting in the Creality bl touch firmware at least my y axis homing errors finally went away but the cr touch does not work still. It auto homes and then the z axis goes up 3 times before completing auto home sequence and stops at least 50 or more mm above the bed. I cannot adjust the z offset that much!! but am able to go in the negative direction now at least where as it wouldn't using every version marlin firmware there is..I tried them all! I also have upgraded my bed to a 750 watt silicone bed so Creality firmware is not going to work at the end of the day for me but I just wanted to try the crealtiy bl touch firmware to see if the cr touch would at least work and it doesn't even though it did fix my y axis auto home kill errors and allow me to adjust z in the negative direction now. Question: When I use the configurations for the cr10s which one do i use for the 2.1 board? The crealityv1? or the Bigtreetech skr minie3 2.0? I tried the V1 and it does not work at all so thats why I am asking. to be honest I really am wondering if I am ever going to get the cr touch working on my 10s as I have dealt with this mess on my own now for about 2 weeks to no avail and if by starting completely over with another custom marlin firmware build for the cr touch and then adding everything back in that is needed for my upgraded heated bed doesn't work I am going to throw the printer out the window as I am at my wits end here!! Your help would be greatly appreciated! update1: I just used marlin bugfix with V1 config file and edited it per your video and now my printer gets homing error kill every time for y axis again! when i start the z offset wizard the cr touch will home to center of the bed but will not exit the wizard after homing in order to continue setting z offsets. tried setting z offset manually and z will not move in minus direction again! This is definitely an all marlin firmware issue at this point!! Can anyone at all please assist?????
Hi. I think the CR10s comes with an 8-bit board, so that will make this upgrade difficult. I dont have that printer, but thats what im seeing based on the research. Can you confirm?
How do you even learn how to do this :O thank you sir! Happily printing away on Marlin :D NOW MY CR TOUCH ACTUALLY WORKS! WOOHOO
Glad I could help! :)
THANK YOU!
You're welcome!
Amazing Teacher !!!. thank you So much.
im subscribe you
Hi. Thanks for the feedback and sub :)
Just stumbled across your video. Very straightforward I am looking to update firmware for Ender 3 Max Neo I ended up corrupting the stock firmware after installing sprite pro extruder. I do see the max neo as option. I also am looking for specific offset locations in the code. Any help would be greatly appreciated.
Hi. I would start with a printer config example that is close to your printer and has the same board. The main thing here is the board needs to be the same. Then, update the build size and any other settings.
Yes I been waiting for this thank you so much. Also question- How should I wire in the cr-touch into a skr mini v2 I've seen a lot of debate about it and I don't wanna fry my board either
Hi. Thanks for the feedback and you're welcome. Im assuming it will be similar to the bltouch but mapping the purpose to the wire color will be important. Im going to play around with that some hopefully this weekend. If I can get it to work, I will make a video on it.
Estou com essa placa e ainda não consegui um firmware que funcione, skr mini e3 v2 e display tft35
@@3DPrintscape okay I just was wondering because I haven't really seen anyone make a video about that specifically but definitely enjoy the Thanksgiving break and don't stress too much about it.
@@bola97_ HI. What issue are you having? Is the firmware building and just not uploading to the printer?
@@3DPrintscape Segui os passos do video e a compilação foi um sucesso, mas não carreguei na impressora, estou com duvida entre o fim de curso físico ou o sensor homing da SKR. Qual indica?
Great informative video.. i got marlin 2.0.9 running on my ender 3 pro now and got rid of some nasty bugs it came with when i bought it. I also tried the CR touch part.. the major problem seems to be when it wants to do the 9 points measurement it moves the CR so far left that it's off the bed. I tried NOZZLE_TO_PROBE_OFFSET but it doesn't seem to make any difference.. i ready about clearing the eeprom and bed settings.. so will take a look at that later. Keep up the great work.
Hi. Do you have a direct drive or anything like that? You can make the needed adjustments by modifying the #define X_MIN_POS and #define Y_MIN_POS values.
@7:41 If you update this, I would suggest mentioning going to the top of the file after modifying the Name as the Enable BLTouch is actually earlier in the file so if you search you would find the second instance of BLTouch in the file
Hi. Im not following. At that time stamp is where you actually enable the bltouch. I guess the enable is the second instance (a couple lines below) but i show that.
Rob, I truly enjoy all of your videos and have learned a ton from them over the past 18 months or so. I absolutely love using your Firmware on my Ender 3 Pro machines. I especially love the Z-Offset wizard. When do you think you will have your firmware available for an Ender CR10v2 with BL-Touch? I just aquired one and really would like to have your firmware on it.
Hi. Thanks for the feedback. I was planning on working on firmware this weekend. What board do you have in the CR10v2? I can prioritize it.
@@3DPrintscape You are THE BEST! Its the 2.5.2 board. Keep the vids coming - I've learned so much from you!
@@gbierba1 I was afraid of that. That board is an 8 bit board, the process is comply different and honestly not worth doing if you dont already have an uno board to push the bootloader. If i were in your shoes, i would upgrade to a 32 bit baord. Either a SKR or Creality one.
@@3DPrintscape and as I typed that last night I was afraid there might be a problem with it being the 8-bit board. :) Cool. I just got it so I'll just deal for now and put on the upgrade wishlist. I was able to successfully push a BLTOUCH firmware to it last night with Cura so at least its functional for now. Thanks for your reply!
I need some help building some firmware. Your videos are by far the best I've seen, and I use them whenever I have any issues, so thank you for that! I have an ender 3 which has several upgraded parts including a sprite all metal hot end, dual z axis, cr touch, and a 4.2.7 board. I cannot get this tuned in to print as well as it should and I suspect firmware issues. Is there a video you would recommend or point me in the direction of some decent firmware to use? Thanks for all your help!
Hi. Thanks for the feedback. What firmware are you using now? Is it a precompiled one or one you built?
Hi Rob, Thank you very much for your amazing videos. I've recently bought my first 3D Printer and came across your videos. They're very good with clear examples and details the others don't have.
I hope you can clear up my confusion trying to get my bed levelling correct on my Ender 3 Pro with CR Touch - I've followed your tutorials and can't seem to centre the head when Auto Home, it sets X=157, Y117 & Z=10. The issue I have is when I try to run Level Bed, it probes the 9 points, but the prob points furthest to the right have the nozzle off the bed (even though the probe is on the bed). My Nozzle X Y Offset is set to -45,-5,0 as per measurement and other videos/forums. Is this the expected behaviour or can you tell me where I'm going wrong. When I set 'Auto Home' I was hoping it would place X & Y around 120 mark. Thank you
Actually, ignore me - I'm being a little dense... I realise now that the CR Probe is probing where the Nozzle would be.... D'Oh! 😂
Hi. Im glad you were able to figure things out. Is everything working as expected with the crtouch?
Great video! With Marlin 2.1, you need to define the probe type for the compile to work, specifying BLTouch, as opposed to manual probe, fixed mount, Z servo probe, etc. I've been having issues with my leveling, with the left side of the bed (the size with the Z-arm) being consistently lower than the other side, producing a slant in my level. Any idea why this might happen?
Hi. Make sure you cleared the eeprom after uploading the new firmware. Does your build plate or carriage have any excessive movement?
Thanks again for this awesome video! 1. Where can you switch between 3x3, 4x4, and 5x5 sampling points? Is that in the firmware code or in the menu? 2. Does this bed leveling data get stored so you don't have to do it every print? Thanks!
Hi. You would update this value #define GRID_MAX_POINTS_X . Most printers store the setting to the eeprom, but i still run the g29 command at the start of each print to get the latest data.
@@3DPrintscape Perfect, thank you!!
I'm very new to the 3d printing world and these videos helped me alot. I'm curious though, why couldnt the firmware come precompiled per machine?
Hi. Crealty has precompiled firmware, this video is if you want to use Marlin. I also have premade firmware on my site.
Hi, thank you for this tutorial, you made great job !
Maybe you can help me with my problem, I assume that during printing heating of the bed is turning off in some time, maybe you can help me to turn it off ?
Hi. Im not following your question. When you are printing, the bed will continue to heat as needed to stay at the set temp.
Love the video. Also want to make a comment for others - do not unzip the Marlin files to either a network location (i.e. \\some-pc\some_share_directory) directly to the C folder. On the first you'll get errors about remote directories not being supported. On the 2nd, it will attempt to delete some temp files and give you an error due to admin privileges. There are probably ways around these - but just save yourself the headache and use a directory in your c:\users\username folder.
Hi. Thanks for sharing this.
When adding Nozzle to probe offset you mention in the video to measure it. How do you measure it?
Hi. For the x and y offsets, you would measure the distance from the nozzle to the probe on each axis. I use a pair of calipers to do that.
I have been using my Ender 3 v1 for a couple of days since installing the CR Touch with the custom marlin bugfix firmware and its been having some issues with extrusion and the nozzle clogging during prints, and some clicking/ skipping from the extruder. It tends to start the prints ok, but has the issues from 1/2cm - 2cm into the print. I have the RET6 GD 32F303 chip on a 4.2.2 board. It appears from some other threads on the net that Marlin was struggling to support that set up (still the case?), and one poster said the issues stopped when he went back to the original Marlin 2.0.6 firmware. Do you have any suggestions?
Hi. I have not experienced this but i know Marlin in general has been having some issues. The bug fixe build havent been the most stable. You can try a new bugfix build to see if the issue goes away, go to a know working version, or even try Klipper.
Any suggestions as to which Bug fix build to try with the 512k GD32F303 chip on the basic/ original Ender 3 printer? @@3DPrintscape
Honestly, not really. The changes can be all over based on what code changes were made. Maybe try one of the full releases to see if that works as a baseline.@@mikebrown8168
Nice Vid! Pretty sure I know this answer already but, does this work with the dreaded GD32F303 chip? or is there a way to edit it so it will?
Hi. My understanding is that it should but i dont have the GD chip to actually test it.
Thanks!
You bet!
thank you
You're welcome
Super helpful. I created a great version on Mac for my ender 3 pro. It builds nicely with no errors, but when I try click the final product and get a “terminal process “bash ‘-I’” failed to launch (exit code 1)
Hi. Can you get the actual error and send it over, it should be in the terminal section and would probably be the first section that is red.
@@3DPrintscape it’s not an error code in terminal. It is an error that occurs when trying to export the final code. I have a screen shot but can’t seem to attach it. It pops up at the bottom right corner. I tried everything and people who have had the issue see to be after an update. So I started over on my laptop with newer operating system and it worked. Hopefully they patch it eventually.

Hi, I’ve been very interested in your videos. I wonder if you can help me? I purchased a Creality Ender 2 Pro in 2023. I am trying to install a CR Touch. I read many articles on the subject and don’t want to blow the main board so I began measuring and checking the 5 pin socket on the board. I have Creality 2.4.4s board, looks like it was manufactured in 2022. Anyway, I probed each of the 5 pins in the hope of checking the grounds were correct etc. I read 12v or thereabouts on each pin when using a multimeter. I’m glad I didn’t just plug the CR Touch in. I’m running stock Creality firmware at the moment. So my question is this, if I upgrade and configure Marlin, will it work and change the pin assignments / voltages etc. for the CR Touch or is my CR Touch interface faulty? I’ve built a couple of RepRap printers from scratch in the past but auto levelling is a new topic for me. Do you have a an email ?
Hi. I dont think changing the firmware will impact the voltage. The 2.4.4 board is 8 bit so that complicates things as well. You can reach out on discord or email. admin@3dprintscape.com
Thank you for all your videos. They are beyond helpful, especially to someone that's new to the hobby. I do have one issue that I hope you can help with. I recently installed the Sprite Pro on my E3V2. The instructions to install the CR touch on the Sprite Pro are scarse but I believe the CR touch mounts right to the side of the Sprite with the bracket that's already there. When I run the bed leveling program the sensor position is too far forward and does not make contact with the bed. Is there a way to adjust were the probing starts?
Hi. It sounds like you need to adjust the x and y offsets in your config file.
@@3DPrintscape thank you. I've watched some of your videos about editing G code. I'll give it a try
@@3DPrintscape What should I search for in configuration.h file for the x and y offsets?
@@ProfesionalNewbie Look for this line. #define NOZZLE_TO_PROBE_OFFSET { 10, 10, 0 }
@@3DPrintscape I've got that set at ( -47, -7, 0 ) and it seems to be ignored. The probe still wants to start off bed by 17mm.
Very useful channel! Thanks. I'm just about to embark on the CR Touch install on 3 Pro. I installed the 4.3.7 motherboard and see it has a socket. I'll watch this and hope I do ok. It powered up and says Marlin 1.0.1 - is that the "standard Creality f/w" you mention? I also got the V2 display (not the touch) but was reading a few negative comments about both that and the touch. Have you updated yours?
Hi. Do you see any bltouch items in the menu? That will tell you if it grabbed the firmware. I have the crtouch on my v2 with that display and it works fine.
@@3DPrintscape Is the fw the same for BL and CR Touch? V2 display now works great :-)
@@randallpatrickc Ya, to the printer they are the same thing.
@@3DPrintscape thanks! I can’t get z offset negative - was thinking might be fw
@@randallpatrickc Thats the software endstops. Can be disabled in firmware or with m211 s0.
Hey rob,
Sorry for the long message in advance.
I had a glitchy screen after installing the creality cr touch firmware. The cr touch had a purple light and would work when i clicked on auto home. I downloaded marlin to my 4.2.2 GD motherboard and i followed your cr touch guide and after installing the new firmware. The screen works but the cr touch has a solid red light and when i click on auto home it wont go to the center of the board. It goes to the x and y stoppers and then goes up a bit. I also enabled the z wizard offset on the advance config. But it doesn't appear when i go to the advance settings on my ender 3. Do you know of any ways that i could fix this?
Hi. Is the z stop connected? If not, connect it. There were only a couple of Creality builds that wanted it to be remvoed.
@3DPrintscape I reconnected the Z stop. The CR touch still has a solid red light. When I click on auto home, it goes to the front left corner. When I turn on the printer, the cr touch's prong comes out twice. Should I try using the creality cr touch firmware again? My only worry is that it will make screen glitch again.
@@IntrovertedN00b Does it auto home and run a mesh (G29) ok?
Two questions
Will this fix my z off set problem with my ender 3 and what am I measuring when you refer to x y for the c r touch
Hi. It depends what the issue is with the z offset and the x and y offset is the distance from the nozzle to the probe on those axis.
Hi Rob, Wondering if you might know. I have a Ender 3 Max, and upgraded the board to the 4.2.7. Do you know how to build a custom firmware for that?
Hi. I made a one off build for someone on discord but i dont have anything on my site yet.
How do you go about setting your X and Y offsets when building the firmware? Did you have to manually measure them? I have an Ender 3 Max and cant find documentation anywhere on what to put here.
Hi. You would have to measure it. You would measure the distance from the nozzle to the probe on both axis.
this tutorial has been great help but i have followed this step by step but when auto homing the prode does not stop the z axis from pushing the extruder into the bed. can you help?
Hi. Can you verify that #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN is commented out and #define USE_PROBE_FOR_Z_HOMING is uncommented?
only one that got the job done with no bs...thanks bud
You're Welcome
Rob, I'm using the Sprite extruder with my CR Touch and I've downloaded on of your preconfigured files from your site. Shouldn't I be able to edit the probe/nozzle offset and then change the bed size (something that needs to be done to make that combo work), copy the files into the Marlin firmware folder then hit the build button?
Hi. If you have a build from the same config file it would work but this is a bit older so im guessing you will need to move all the changes over to a fresh copy of the config and binaries.
hiya have run the bin file and it seems to have partly worked but is now comming up with eepprom verion error. Any advice would be greatly appriceated
Hi. Try to clear eeprom (reset to defaults). If that doent fix it then try to build/flash the firmware again.
