Can I ask why you follow the first schematic?
Yes the last one is mine. Since then I’ve changed the Z drive to DQ860MA to match the others and run off the 68V supply. That allowed me to remove the 30V supply.

As my new Mk4 machine uses 2 Z steppers I’ve added another DQ860MA drive off the same supply so there are 5 drives in total. Otherwise all the safety relays and interlocks are the same. Works well.
