K8200: problem with adjusting the stepmotor driver


I just finished the assembly and wiring from my K8200. But I have problems with adjusting the voltage from one of the motor driver. For the first three driver it was ok. I connected the multimeter, measured the voltage and adjust it to about 0,425V.
But on the last driver (x-motor) I have no chance to adjust it. It drops from 1,6V to 0,0V. I also connect another motor but is was still the same issue on the driver x.
Have anyone an idea what I can do now? Should I change the driver?


You can test the driver by swapping it into another axis. If the problem follows the stepper card, you need a new one.

Thx for the info. Yes I tested it already with another axis but its still the same. So I will change the driver.
