Isel stepper motor driver + Ultimaker original motherboard working

I’m so happy it works. So far only X axis.

 

I’m using +42V and +5V supply from Isel power brick to power Isel step drivers (X and Y). I also added MW switcher to get +12V supply for Ultimaker motherboard.┬áNext step is connecting Y axis and adding stepper drivers for Z and extruder.
