I have a c11g cnc4pc breakout board. I was using 3 geckos (2 servo drives and a stepper), but I'm replacing the 2 servo drives with a Granite Devices vsd-xe dualdc drive.
The bob has a selection between 5v common (required by gecko) and a gnd common (required by vsd). the jumper is for all of the commons, not individual.
how can I run these 2 controllers side by side?
Machinists do it with greater precision and less tolerance!
