Hopefully this is the correct forum; it seemed the closest fit.

I'm planning to CNC both a mini-lathe and mini-mill. I've already purchased drivers, but before I go further I want to make sure of what's necessary.

Am I correct that (without doing extensive rewiring every time I want to switch machines) I'll need separate power supplies and breakout boards? I apologize in advance if this is a really obvious question, but I've had a hard time finding it mentioned anywhere.
