Hey all, Total stepper newb so looking for some help here. Having trouble with my stepper motor project. I'm using: Wanta DQ542MA 2H Microstep driver NEMA 17 stepper motor from open builds store Arduino Uno 24V DC power supply I have PUL+, DIR+, and ENBL+ wired to pins 5,6,7 on the arduino, and PUL-, DIR-, ENBL-, DC-, and Arduino's GND all wired together. The DIP pins I have are set to 1 - OFF, 2- ON, 3 - ON, 4 - OFF, 5- OFF, 6 - OFF, 7 - ON, 8 - ON This should give 1.46A Peak and 1.04A RMS on the motor which is rated at 1.68A/phase Also set at 1600 pulse/rev for 1/8 microstepping (200 steps/rev) When I first turned it on, I forgot to set the DIP pins so it was at the max current of 4.2A peak / 3.00A RMS. I didn't have the arduino connected, and connected the DC power supply and the A- wire started smoking and melted the insulation. I removed the power as soon as possible. Now only the red PWR/ALM light turns on, which per the spec sheet means "ERR: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage protection" What's going on here? What am I missing? Did I just fry the driver? Thanks for the help!
