My M200 recently developed printing artifacts that look like ringing but in Z direction.
I took couple of photos - both parts are printed form the SAME file (same zcode), red is older (~1.5 years). Material is the same (Z-ABS) just in different color.
Yellow part has horizontal bands that do not show up on the red part printed earlier. This does not look like belt tensioning problem since bands are in Z direction, I checked them anyways but it does not change anything.
Printer has ~3k hours on clock now and some part clearly is worn out or loosened, but which one should I check first?
