Received a new DX head in the mail and flashed 18.1 to it. When I get to the z calibration, it will run and state successful… however it will leave the right nozzle down and scratch the board. I tried reflashing 18.1 and manual calibration. When I go to manual calibration, the left nozzle will work just fine but the right nozzle when I hit save just sits on the screen.
Unregard, issue was due to friction pulling the nozzle up as it fed about 10-15mm. Wish it used the motor or had a locking mechanism to hold the nozzles down when printing.
