Mainboard K8400 may be broken?


#1

I have a big problem with my Vertex K8400, I think it is not working after calibrate two DRV8825 stepper driver board, I burnt one of them, I bougth and replaced all of them, but z axis is never working. We test everything, in the screem all look normal but the z motor don´t work.
I am looking for buy another mainboard but first I need to know this is the problem, the new mainborad is very expensive 120€. ¿There are any way to make sure the problem is the mainboard?

I bought this stepper drivers:

I need help,
Thank you

First before you buy another mother board.
Unplug then replug the cable on both ends.
The side on the motor can be tight and give you the impression that it is seated when its not.
Next swap the motor with one of the others to see if that is where the problem is.
