So I have a quick question.
If I am using ramps 1.4 as a cnc only controller,
Do I need to hook up 12v to the power inputs if I have the USB cable plugged in either via PC or USB Wall plug?
I won't be needing the D8, D9, D10 outputs.
My motors are opto isolated in the driver itself, it only needs 5v signals, which I assume as long as the board is powered via usb it will accomplish this task.
Thanks!
Once this is answered and my drivers arrive I will post a pic of my setup once completed.
