What i am doing wrong with mach3?? trying to config machine.

Sure ?
The driver is only 4 wire.

Not 100% sure. . . But I see 5 wires out the motors and where the connectors enter the box there's Green wire with red rings with what looks like a resistor that goes to the daughter board next to the drives. I suspect this is common and the 4 wires on the drive are A+ B+ A- B- like this.



But I could be wrong.!!!

Erm...After checking the parker sd3 specs it says bipolar drive so MC could be right and it's shielding or something. . . . More investigating needed me thinks.

Think best thing you could do scnc is take john up on his offer and throw it in car and let him check it out.! If it's been working then chances are it will be a quick fix or just a setup issue.
At the very least he'll be able to check out what stuff is and where it goes.!
