I was cutting the plastic plate to mount the controller board. I got through the first vent and the y axis quit. I get no lights when I try to move the axis. I have the vapor v3 board and the nema 23 high torque motors.
I am having a similar issue. During motion one of the y axis motors deactivates and the light turns off.
Are the drivers overheating? This would happen with some of the lower amperage drivers if not cooled well. I am not familiar with the vapor board.
