Thanks guys, alls im planning on doing is running 2 servos for my X, 1 for my Y and 1 for my Z and a channel to control my VHF Spindle, im after the simplest plug n play option out there, but it need scope for future add-ons. how would i wire to X servo drives up using a BOB, could i just take a single step and direction output and split it off to both drives to keep them synchronised or can i use individual channels and somehow configure it in mach3 setup?
