Smoothstepper ESS
Mach3
Breakout board
I'm getting things ready to go and found a question regarding the 5VDC on BOB.
There is a jumper on the ESS board plug 1 if connected it, it sends 5VDC to the BOB. If I jump it do I need the USB CABLE BETWEEN THE BOB AND PC?
or do I need both?
Or do I need 5VDC at all since I'm not using the relay?
thanks
