I just changed nozzle and moved the printer to another room. After turning it on and hitting 'initialize', the Z axis motor just tries to go up constantly, and it starts to struggle at the top not stopping. This makes the motor click, and if I pinch the belt by hand, it recognizes that the motor has reached its limit and beeps, this finishining the initializing.
Does this mean the belt or some other part is loose? Pinching it to make it stop is not ideal*, because it probably moves the Z position slightly.
