LMAO this is awesome

Check your bed bearings. I had this happen when one of my bearings started to let go. I also found a deformation in the bearing channel, so I switched that unit to MGN12 rails and the issue went away.

This is why I have GCode to unfail the print prior to resume. It Rehomes xy so it can pick up right where it left off even if things get moved.

Interesting technique. For this type of accent work I usually extrude the text into the surface 1-2 layers deep. At that layer I’ll swap filaments, print 2 more, than swap back to my original color. This achieves the same effect in a slightly different way.

I have some Octoprint Pause scripting that will auto park the print head and lock all motors. It will hold the job while you swap filaments. Upon restart it will do a purge in place, rehome XY, then continue its job from its pause coords.
