Kobra Go layer shift

I created this video on 3D printer layer shift in an effort to assist anyone struggling with layer shift issues. Let me know if it helps or if you have any questions in the comments.

Wow... After all that I have learned about 3D Printing, there is always something that can catch you off guard. The issue I am/was having was layer shifts. I've improved the mechanical connection to my Y-axis motor, used locktite and tightened the belt etc. But as i reached the end of your video, I heard and saw what the final issue could be, and that was accelleration and jerk during slicing the model. Obviously an oversight and is easily done, but I hope this is the last bloody thing holding me back because Ive got large models to print and do not want to waste anymore material esp at that scale on issues like this.
So thanks for posting this video... sometimes all you need is to hear someone mention or pinpoint the issue out so it gets you back on track.
So thanks again 🤓👍

Hey man.

Great video as always, keep up with your great work 😃👍

Man, thank you so much for this video! My issue is the acceleration that is set too higher than my printer can handle :)

One issue I had that caused layer shift appeared to be Cura-specific: I set the wall thickness to a value not divisible by the nozzle size. In my case, I had wall thickness set to 1.5mm, but the nozzle was 0.4mm. What would happen is that anytime the print reached a point in the model where it would start a new wall, there was a chance for an offset/shift to be introduced. Setting the wall thickness to 1.6 or 1.2 (values evenly divisible by 0.4) avoided the issue.

Exact same issue as above. Belts were fine, but found that the cheaper motors supplied are not capable of higher speeds with rapid changes in movement. Had to slow it down and it worked. I imported the configuration of the "owl.gcode" that came with the printer to copy the correct speed settings and have not had a problem since. You can upgrade the motors for better performance if you wish.

Most the layer shifts I see come from the print sheet and because the bed heats and cheap manufactures use ground iron magnets which weaken with heat above 50 degrees C and prolonged use, so the sheet moves basically what you did with your hand

Thank so much, thas was exactly my problem

I had this problem with the y-Motor. I replaced it with a stronger one. It was mainly the acceleration and the travel speed that caused the issue.

Have you tried to check Vref? I have exhausted any other alternatives. I am taking apart my machine soon!

[dannaeyniky]

What maximum speed do you recommend to avoid layer changes and what acceleration do you recommend?

Hello, thank you for this video. I followed your steps, but I still get layer shifts. And it seems to be the y-axis. Any suggestions how to fix this?

My anycubic keeps printing an outline that’s connected to my prints causing problems with articulated prints

when this happen to me i change the micro ssd to other better quality micro ssd and all come back to normal!

You are blaming all the wrong things. You should examine your Z screw. Make sure any set screws that clamp down on the zscrew are tight. If the Z motor's movement isnt translated to the zscrew 100%, the gantry dosnt raise up enough, for the print nozzle, to clear the print, and has a collision.
