I found a solution, the electronics box came wired with the motor plugs facing the wrong direction. The instructions say the red wires should be facing forward, but I assumed they would be plugged in correctly by default, so I left them that way. When I reversed them, the Mintemp error stopped happening and the motors started working fine. The problem I have now, is the up and down motion keeps going up and attempts to squash the extruder against the top frame bar when I run the auto home option. What would I be doing incorrectly?
