Hi Guys

I'm building my first machine and wiring up the steppers and drivers right now. I have 2 steppers on the Y Axis, one either side each driving a ballscrew. Now, my question relates to the DIP Switch settings. Both these motors have their own driver of course, but these drivers are then both wired to the same points on the BOB so they both receive identical signals to precisely co-ordinate movement, BUT how will this affect DIP Switch settings? I'm OK with switches 4-8 but when it comes to 1-3 do I go for 4.2A on the X and Z and 2.1A on each of the Y Drivers? I heard somewhere that each motor in this configuration runs on half current. Does that make any sense? Sorry for my lack of knowledge in this area, and I did try asking my supplier without success so bugging you guys with a question that's probably been answered somewhere else WAS a last resort

Any assistance gratefully received.
