DM542 stepper motor driver power stage light turns red Hi everyone. I am currently building a CNC milling machine. The milling machine is controlled by raspberry pi 3 b+ and Smoothieboard v1.1 with DM 542 stepper motor driver (https://www.oyostepper.es/goods-1249-Leadshine-05-42A-20-50VDC-digital-stepper-controller-for-Nema-17-23-24-stepper-motor.html) and 1.8° 2A motor. unknown The 1.8° 3 A axis is run by a stepper motor driver, as the Smoothie board can only control 2 A. I control the two Y axes and the Z axes three times by a Smoothie 2A board. Unfortunately this does not work. I had to buy two new drives and plug them into Y1 and Y2 - they run in parallel. It worked until I ran the CNC and it worked. It's too far to the left for me. I had to hit Killbatten. I unplugged the whole system and turned it back on. When the controller is turned back on, the light suddenly comes on Red light on the power amp. It took me a while to figure out why. When I removed the Enable + (+5V) cable from the power amp, the light on the power amp turned green again and the machine started working. When I try to plug the cable back in, the light turns red again and it doesn't work anymore. Can anyone tell me why this is happening?
