Please Help- Velleman K8205

Hello I bought the K8205 addon for my 3D printers.

I changed the motor driver. I’ve done the setup of the motor driver of the extruder to have 0,425V.

What do I need to change because when I triy to print nothing is working. Do I need to change other parameters on the repetier because even when I changed the temperature I have no results.

I’m not familiar with the K8205, but if the new driverboard is a DRV8825, the voltage should be set to approx. 0.9 volt.
