In case anyone else didn't have the pop-up window he had when printing -
Go to File --> Preferences --> Change Print Window to Pronterface UI. Just saved you a few hours
Duane Kord thank you
Thank you 👍🏼
Thanks Duane - Yes you did save me hours!
thx
Thanks dude. I dont usually read the comments. You saved me after a few days of saying wtf to myself. what was I doing wrong?
This is the ABSOLUTE BEST tutorial there is, I had to calibrate mine again because I had to change a part and ... (long story) and I searched this video for nearly 30 minutes, I just had to find the right words.
Thank you so much! The only vid on yt that goes through the whole process step by step
You're welcome!
thanks man you made this process so simple!!!!
Thanks very much. i couldn't get the auto level to work, but its all good now
Excellent video....thanks. You made this much easier.
Thx finally found the right vid
You know if this is the same setup for Marlin? For an anet printer? Is it the same steps as it is in the video? thanks.
does the start/end-gcode has to be on every print after that? Now when I try to print anything, it goes and checks like 10 different spots before it will start... that's fine except half of the prints, my sensor is off the bed.
I had also negative value from g30 probing inserted it as positive z offset and getting nice first layer
THIS VIDEO IS PERFECT
What are the benefits of this version over version 1 in the previous video?
Thank you so much!
hi fella i having trouble my x and y are well off how do i senter of bed i followed the tutorial to the T but well off and i noticed i all so carn use my lcd dontrols now as well
Hi... first time uploded resulted in a bricked A6, already recovered, but now I manage to upload the original A6 AutoLevel configuration file but as soon as I make the necessary changes for the BLTouch sensor I get a message stating that the sketch is to big to fit on the memory, any experience on this?
Hi! Amazing video so far, I am at the 11:13 mark in the video and on my screen from cura that pop up doesn't show up. It shows up operational and detecting bauderate and such however none of the buttons show up other than print. Did i do something wrong? or is my version a different version? I have no idea, everything else looks the same as yours though
Dylan Purcell this happened to another person too. I think they reinstalled cura and that fixed it.
Same thing happened to me two days ago. Even tried the new version. Two computers. No control panel. Gave up using Cura yet again (Cura is the reason I bought Simplify3D several months ago, plus, S3D is awesome) I used Simplify3D to do all my programming.
Any recomendations on where to look to get my points on the bed? Ive looked and looked but everything i find is older and it doesnt match with the newer software....
The points should be defined somewhere in the source code...I have no idea where though.
Not a bad tutorial at all, has a lot of useful info to help the process along, but the version of Cura included (and the new downloadable one) doesn't have a machine control panel. Using Simplify3D's machine control panel the steps are mostly the same and I've done all my programming through it.
How do you change the setting for sensor, mine says open when its close to the bed and light is on. It should say triggerd
Great video. I altered my configuration.h for my BLtouch and now when I print, the nozzle travels down instead of up with each layer. Can someone tell me which z code I did wrong?
Kyle Dillinger I'm not sure, maybe someone else knows. You could also try posting your question on the Skynet Facebook page.
My sensor is and 18mm no sensitivity screw, the thing keeps crashing at the G28 command I have it installed in the back of the carriage assembly behind the nozzle, I picked up the .h profile for a 5 button display which on my printer , would that be the cause for the whole thing just none stoping crashing the bed and dang I have a 3mm glass bed, thanks...And I agree this is the best video I've seen explaining the process thank you for taking the time and sharing
Thank you very much for sharing this just for a question I'm using a stock auto leveling sensor but mine came different from yours , it hang on the left side of the extruder .so my question is what configuration file should I use ???
seetcas that is a good question! unfortunately there is no configuration file for that set up that I know of. You may be able to use one of the configuration files for the non anet sensors as I believe these are usually side mounted.
ProjectTube I will try to use 12mm profile
Give it a try, just be ready during the auto level sequence to pull the plug if the sensor misses the bed making the nozzle push down into the bed.
ProjectTube Thanks
At step 8, when apply g30 command, z value more than 60. How to offset to negative value as max offset is 20?
hai when I enter g30 my x axis go to 139 any suggestions
Hey thanks for the tutorial, I was following the written guide they gave, and when doing the leveling before the print it pushed so hard on the bed the glass broke, turns out I found out when watching your video I wrote the wrong offset (took the position just under) so the offset was 10.6 instead of 0.57 ..
Cdek654 same thing happened to me. I don't have a glass bed so no breakage but gouged my bed pretty good and killed the nozzle.
Ouch, I'm glad I have spares, and the bed / nozzle aren't damaged! :P
Hi
did the extruder moves to its previous position after you entered the command G30 x110 y110???
The extruder should move to and probe (if it's already there, it won't move in X Y, just Z) the same spot. G30 means 'Return to secondary home position'. I think in this case it's been modified to move to and probe.
Whenever I input the command for G28 the zaxis just stays in one place and doesn't go down can u help?
Do you have to print with Cura or that's just for the setup?
97JoMiller just for setup. The earlier versions of cura allows you to control your printer through usb and enter in G code commands which make calibration a lot easier.
Grande vídeo, esses comandos são para sensor capacitivo também o meu é com altura de 4 milímetros antes da tabela como configurar ?? Se você pode me ajudar ??
Hi,
will this firmware working with Practical 6 - 36V Auto Leveling Sensor?
Thanks
+KRONOSX Kronos Addict this should work with any sensor assuming the sensor is installed correctly and the firmware is calibrated for that sensors offset.
I wish I'd seen this video last night when I was setting it up. Everything went fine until I got to the z offset part reffered to at 17:00 minutes into the video. I merit crashing the nozzle too. I edged up doing it manually and getting it. I could have saved a couple of hours by watching this video. Somebody linked me to it over at the a net Facebook page. I was gonna make a video showing this exact same thing. No need to now. I have the a6. Thanks
I feel your pain I now have a nice box shaped line carved into my bed from the nozzle scraping alone it the first time. Best thing to do is you get a positive number is set Z to 0.00 and start moving down from there. The biggest advantage to version 2 is the ability to easily adjust the Z offset with the M851 command.
ProjectTube I subbed you. I'm interested in casting process too. I ain't ready for that yet, but it's filed away as one of the next projects.😁
Would the difference in height of the bed change this value? Since some people might screw it in more or less causing a unique offset for each A8 owner?
ProjectTube I had to reset my z offset yesterday because I had to drop the heat separator tube about 2mm to insert a filament guide inside the extruder. This time though the offset number was low, it was something like 2.20 millimeters, so I used the exact procedure in the manual by entering -2.2. This time it worked perfectly. The comment you made about ," if it's a small number, it should work fine", was right on the money. I think it's a problem related to the cube sensor.
Now, I'm trying to get the x and y sensor offset dialed in. I got it close, which is probably close enough. To set that one you have to change some values in the config h file, reload it in the skynet folder, then you have to reflash skynet onto the printer. I got it within 5mm, but I don't think that the cube sensor senses in the exact center of the sensor which is why, I'm off a little bit.
+DJDevon3 the Z offset if I'm not mistaken is a measure from where your nozzle is when your sensor triggers to where the bed actually is. It's the amount the nozzle has to travel down after you sensor triggers to get a good first layer.
Will this method work with an Anet A6 and a BL Touch? Thanks!
Yes it should, just make sure you enter in the correct bed dimensions for the A6. I believe these are listed in the documentation provided with Skynet.
So nice of you. My A6 has been shipped and I know I'm getting a bit ahead of myself but I really appreciate your response. 3 subs from me.
Not trying to be a smartass. MK LL is actually MK2 aka MK II, it means Mark 2. They're not lower case L's, they're capital i's. One reason many people don't read it correctly is simply because of the font used. If it was displaying in Times New Roman it would be very easy to recognize the capital ii's are meant to be read as Roman numerals. The word mark is a common prototyping designation. Ever seen Iron Man? :) Great video. I'll likely be coming back to this one when my A8 arrives. Looking forward to having more conversations with other A8 owners.
+DJDevon3 Good to know! I had no idea, but that makes sense. Thanks for the info!
I got 0.39 as Z offset and it works well in the center and one side of the bed but when i print large things , one side of the bed the nozzle is too high than the other side, what can be wrong? why the sensor is not compensating that?
Jasson Sanchez I'm not sure the firmware should be compensating. More then likely your bed is warped leaving a dip in it that the software can't compensate for...im just guessing. I have problems with larger prints as well and I think my bed is warped a bit.
when I set my printer to home with the new bed level sensor, it just keeps crunching it down and never stops trying to lower... I have to cut the power from it because the motors won't stop like they used to when it hit 0 on the Z stop. The Z Stop is plugged in correctly. I don't have a flast board on mine that mounts to the back like yours. Mine appears to mount on the front by the fan.
Most likely your sensor is not triggering. How far above the tip of your nozzle is your sensor?
the size of a zip tie... I set the nozzle down to where I normally set it then adjusted like you put in your video... the sensor is on the front instead of the back, would that cause an issue?
When the nozzle comes down and hits the bed is the sensor over the bed?
yup and it's plugged in to the z-stop
turns out the plug was wired wrong, I had to reverse the blue and brown wire to get correct power.
Hello, when i put "M851 Z0" on cura, after that dont shows anything, when you pressed enter shows "echo:Z Offset 0.00" and for dont appear anything. Can you help me? please.
Same thing for me at first. Just reinstall the software and it should work
thanks, i will do that and try again :)
My computer can see my A8 but has a yellow exclamation cause it doesnt have the drivers.. so im back to square one.. marlin and skynet are a no go so no bed leveling.
What version of cura are you using in this video??
Its an older version. The newer version doesn't let you connect through USB.
Ok I did the update but my printer didnt restart. Is it supposed to? I already had the older skynet already.
So you can print directly from the computer through USB?
With the older versions of cura you can.
I can't seem to find the "Tutorial" To print out. Where Do I find it?
Skynet folder, Documentation, "Tutorial" folder.
I am trying to do this on a mac. How do I install the Anet files into the Arduino IDE so I can transfer the files?
Unfortunately I have no idea I have never worked on a Mac before. Perhaps someone else can chime in?
When I click on home, it will go down to the spot it should be, I see the sensor show a red light for a second, then it brings the extruder up about an inch off the print bed, is that normal?
+97JoMiller yep
You mentioned a better sensor than this one, what is the better sensor?
+Mike Carter well i feel like the aftermarket sensors like this one are better but I don't really have any evidence of that.

make sure you get 8mm, it's much better.
Is there any way you can post your configuration h file . I'm so frustrated my home is about 50mm from center and 5 mm to the right just about. ( basically to the right front of the center)I'm so frustrated with doing 3d printing at this point. I have a anet a8 but it doesn't look like the others the bed has each wire individually in the connector and they may have listened to the complaints and upgraded items because some upgrades I've seen people do I don't need. Ex. Bracers , mine doesn't shake . Any help would be appreciated I have skynet 2.3.2 loaded but it crashes into the bed also. I have a Uspasp and reflashed anet a8 and it works fine so I know it's not the printer alignment. But I want the safety features and reloaded skynet. I followed the guide and the only thing I can thing I can think is the settings in my configuration h are wrong. The original anet firmware printed fine any help would be appreciated! I really dont want to put my anet in a room and monitor it during the whole print.
Dont use skynet, use Marlin more opcions nd with some youtube tutorials you will learn to configurate de hot bed
i cant copy and paste the start gcode, can anyone post it so i can copy please?
how do i change the logic on the sensor as at moment it is deactivated when it near metal
Rob Brown I'm not sure, it likely somewhere in the porgramming. I'd post your question on the Skynet Facebook page.
sorted it can you post the gcode as it is not copyable from the document
I dont get that window in cura when pressing print via usb I get another one.. without the move and command
Yarni Pels I believe it's in the settings to change the print interface to the prontorfaceUI. if I remeber right it's under File, preferences
Great thanks! :)
hai would this setup work with v.1.1alfa
+sky rim no, but I have another video for version 1.
Facebook page is not available, any leads on this?
thanks,
Rodrigo Delgado github.com/thijsk/Skynet3d
my hotend temp says 149 after i turn it on but it is ice cold and when i try to pre heat the machine it shuts down with error code PLEASE HELP
+SOUTHSIDE FILMS sound like a faulty thermoresistor.
Is anybody else know why it doesn’t see the Anet a8 in the cura
I am getting a negative number on the last step as well... sensor is new out of the box today... any idea's?
+Big E FPV not sure, unless we are both doing something wrong or there is a issue with the firmware as the documentation says it should be a positive number. Try doing what I did, do a M851 z0.0 and slowly decrease it until you get a good first layer...M851 Z -0.1, M851 Z-0.2 and so on.
How did you INITIALLY set your sensor when you started this? Lets take that out of the mix...
+Big E FPV with version one I did it manually. I adjusted the sensor hieght so that it triggered before the nozzle hit the bed. Then using cura to lower the z axis in .1 increment counting how far down the nozzle needed to go in order to be a sheet of paper thickness off the bed after the sensor had tripped and entered that value as a negative number. That's the offset value the difference in hieght between when your sensor triggers and your nozzle is at the correct hieght to print.
I'll see what I can mess with and figure it out...
2 hours of messing with it and still getting a negative reading for the Z at the end....I've about given up..
So if your Z comes out like 1.13 then I dont need to do all the extra steps?
Michael Lewis if your z comes out to 1.13 then you'll do a M851 Z -1.13 and then a M500. try to print and see how the first layer prints. if it's still not close enough start moving the z offset down like M851 Z -1.5 and so on.
Wow was not expecting a reply so late but printing now it looks pretty good! Better then me trying to level with the screws only thing is the bracket I printed out I'm not sure how it's held does it screw into the drilled hole on the bracket for the extruder? and secured with the nut?
Michael Lewis not sure which bracket your talking about. The stock anet sensor bracket attaches to the back of the extruder with two long screws and the sensor is held onto the bracket with screws and nuts.
ProjectTube I had to make my bracket since I got the sensor only and not the Anet with the sensor with it
Michael Lewis oh ic, well my original bracket broke so I had to print one too. Make sure you don't over tighten the bolts holding the bracket to the extruder it will bend the bracket and eventually it will snap....whoops lol.
buy a mounting plate to move the sensor... if only u had a device to make a mounting bracket... some sort of... printer...
Rick Fx. hahaha

Thank you :)
what about simplify 3d how I can add the. G-code ?
+seetcas I've never used simplify 3d so I can't help you there.
When you double click on the process there is a g-code tab. imgur.com/9zAhcpH Just add the G28 before G29.
Mike Carter you meant add g29 after g28 ? am I right ?
Yes, good, your paying attention.
isn't the most current version 2.3.9?
+Nick Anderson yes, 2.3.9 has been released through github but only 2.3.2 has been released through facebook....if that makes any sense lol. I assume the setup would be identical in both version but I could be wrong.
its not bringing up the window to adjust the printer when i click print
+scout413 check this out, should help.

hey buddy I got a tip for you. I'm guessing your using Movie maker? your screen captures are fuzzy I know how to fix this if interested message me
Great guide once I take on the dark side I'll be using this as reference
I did this video step by step because I forgot a few Gcodes along the way lol. Thing is....I flashed the firmware and forgot one very important thing..... I didn't save my ESTEPS...I Was going crazy trying to figure out why my first layer wasn't right...Yeah....Make sure that you jot down any important things that you might have spent HOURS WORKING ON TO GET PERFECT (cry...) Learn from my mistakes lol.
I just dont understand I have the same everything yet I cant get the same interactive interface that you do. I have scoured the internet trying to find the same interface with the freaking circle and I get nothing and NO ONE is telling how they get there all are ASS-U-ME ing that we all just know how... big long exasperated sigh... guess I am just too stupid to understand.
