Looks like it’s missing steps.
Check your pulleys tightening screws first, then check if something isn’t binding somewhere.
From what I see on your 3rd pcture, the problem seems to happen on the left to right axis.
Your bearings seem particulrly dirty so maybe one’s not turning smoothly anymore
Nope, maybe I’m pecking too deep? This makes no sense. I made several before this, exact same file, same wood, no issues ever. Now I can’t get through 15 little holes without failure. Aargh!!!
tightening the big long vertical screw that runs through this a bit all seems to have removed most of that wobble… and it’s now cut ~70 holes without an issue
So, started having issues again. Found a…flaw. went back and looked at the old videos when this started, and… That bearing, that’s not where it should be. The z-mounts both have broken by the bolts and moved apart, showing the bearing to lift.
Having them reprinted now. But this is likely the cause of so many issues I’ve been having lately
