I’ve checked the belts for debris (there was none), made sure the belts weren’t loose (they were not) and after removing the printer head noticed there was a broken wheel.
I’m so sorry to hear that you’ve hit this snag! I see that you reached out to us directly via email, and we inquired about sending over photos of the Carriage Plate. We’ll send over the next steps to get this part replaced. I’ll close this thread for now, and continue following up directly.
