Y-Axis Ginding noise and losing alignment

Every time I go to print something the y axis will randomly make a grinding noise and lose alignment. Any idea what this could be?

Give us more infos, photos, is it alwasy at the same location and so on?

It doesn’t seem to be in the same spot every time it’s at random, sometimes it’s at the beginning of a print sometimes it’s an hour in, it only does it once per print. I usually print directly from my computer. Give me a few min to get some photos/videos.

Reach out to support. They will likely tell you to swap a module. About halfway down here is Edwin, snapmaker support, with a specific check to do.

That post seems to be for another model but I will check it out and contact support. thanks for your response!

Dangit, every time…

The root cause of that one was lead screw mis-match so that’s probably not the issue here :smiley:

In that case have you checked if there’s debris inside, maybe something packed that’s rubbing? Can you move the axis by hand, does it feel even across, or some resistance?

I’ve looked in the Y-Axis and it looked clean. When I moved the axis by hand it was smooth. I’m currently printing something to try and recreate it.

Oh i forgot to add my printing settings
