will do, thanks

but what about the jumpers on the drivers?
is it possible to fry something if I don't set anything? or is the setup or is any setting "safe" in this setup and it's just a matter of power and speeds?

General Mach Discussion / setup questions from newbe

Hey there

I'm setting up my first CNC machine, and I have a few questions I hope you can help me with:

my setup is this:
Drivers: http://www.wantmotor.com/ProductsView.asp?id=257&pid=82
PS: http://www.aliexpress.com/store/product/Best-Selling-Wantai-Single-Output-Power-Supply-350W-36V-S-350-36-for-CNC-Router-Grind/511874_677179176.html
motors: http://www.wantmotor.com/ProductsView.asp?id=160&pid=80 the 57BYGH115-003 (second from bottom)

so my 2 questions are:
1. how do I set the jumpers on the drivers ?
2. I see 2 setups for the wires from the pul and dir pins - one is to connect the positive pins to the BOB power supply +5 and the 2 negative to the BOB control pins,
and the other is to connect the negative to ground of the BOB and the positive to the control pins.
does it matter which setup?

thanks so much for your help
