Hi, i have a problem with my 3d printer, it starts to print but after a while it the Y axis goes mixed up and wont working anymore. You can see in the video:
Then i need to turn it off and on that the Y axis works again.
Hey Vanja,
I think i can help you out. Please let me know where are you from?
You can also contact me here: contact@3dprintaj.com
Cheers,
Marko
You have a custom Y platform - are you sure it’s still screwed to the Y transport bracket?
Are you sure it’s your y-axis? Your x-axis belt tension seems way too loose. The belt shouldn’t be able to swing around like that.

It’s hard to tell the issue with just the video. What upgrades have you done, what slicer, what print settings, is that a stock build plate, are those stock bearings on the y-axis?
It seems like the y-axis is getting caught on something, check and make sure there’s nothing getting caught on the y-axis. Does the bed move freely by hand? Is the pulley for the belt getting stuck?
It’s probably an issue with the crappy lm8luu bearings on the printer, and you might have to replace them.
