Started getting these odd artifacts that look like small layer shifts occurring every so often. There was a squeaking noise that seemed to accompany these so I tore down the printer after trying just about every other maintenance or troubleshooting step. Turns out there was a lot of debris around the idler pulleys and buildup seemingly from the belts on some of them.
I did some digging and while it seems I can replace the tensioners, I can’t service the frame pulleys at all. The ones in front were similarly dirty.
Not sure what my options are here. I’m over a year out of warranty and I tried plenty of other things to try and fix the issue. Swapped in a different extruder with brand new gears and another 0.4mm hot end, did the belt tensioning procedure, dried the filament, and cleaned what I could all around the printer. Recalibration was run as well. I also cleaned and lubed the Z-axis screws about a month ago.
I don’t know if the pulleys are loose or anything. I went ahead and ordered new XY belts since they were cheap and figured I could try to clean the pulleys while replacing them. Really hoping my X1C isn’t dead after just 1,400 hours.
Not sure what’s causing those tiny holes either. They were around with this filament before the shifting artifacts showed up. I’m using PolyMaker CosPLA here. The shift artifacts show up on other filaments and materials as well but not the holes.
