I 1st of all must say thanks for all the support I have received from forum members which has gotten me thus far. I finally got my wiring properly configured and now in need of Mach3 configuring for my motors. I used a Stepper Calculator posted and tried the numbers on the inch scale.
I am useing the following equipment and hardware.
Mach3 software (latest version)
Smoothstepper ESS
CNCroom MB3 BOB
3ea DM860A Microstep stepper drivers. (Nema34 Stepper motor driver DM860A 7.8A 256micsteps 24~80VDC LONGS)
3ea power supplies. (350W,48VDC Power Supply 7.3A for Nema23&34 Stepper motor&Driver CNC Router)
3ea Nema 34 Bi-polar motors. (CNC NEMA34 Stepper Motor 1232OZ-IN 8.7NM,5.6A,118mm,4leads) Stepper motor

I am only using XYZ axis and drives are CNC SFU1605 Ball Screw SET. My power supply is set at 48V.
Any help with Moto tuning and Setup Motor outputs, not sure DIR LowActive or Step LowActive
Using the Mach3 MPG I am able to activate each motor nut they seem to chug and whine and miss a pause in rotation. I have verified the motor wiring to stepper driver is correct. I have my BOB wired using VCC connected to PUS+ and DIR+ then XS- connected to PUS- and -XD onnected to DIR- .
I have tried to list everything I have done, any help will be mucho appreciated.
Thanks Tim
