hi Dont give up yet…I had the exact same issue. I had two items wrong. first I a bad proximity sensor which needed to be swapped out. Snapmaker sent this very fast. Then issue persisted and found out embarrassingly I had a my cables plugged in incorrectly y and z were reversed… as soon as I fixed the cables the auto calibration worked flawlessly.
instructions for assembly are quite good but you need to pay attention to small details and dont rush. I took my time and still managed to put some wrong screws in wrong spots. plus the cables…
snapmaker support I had was brilliant and they went above and beyond to make it right. even with the bad assembly being my fault. they want to help. quality and service is awesome in my opinion.
this was the first 3d printer I ever bought.
