This particular U1 is junk
This particular U1 is junk. Brand New printer that won't work. It either fails to pick up the toolhead, drops the toolhead or falls to park it correctly. The one print I did get to print it dropped the toolhead twice and both times when I restarted the print after replacing the toolhead it layer shifted. It also tells me that I need to do a manual bed level. This is unacceptable for a printer in this price range.
