Title: Axis slaving question
Post by: jdm033056 on April 30, 2020, 10:22:36 AM

Sorry if this has been discussed. I found info on slaving, I need to slave axis A to axis Y but I have a rack and pinion system not a ball screw system so I need to reverse the rotation of one of the motors. I'm a newb to Mach3 and to CNC so is this possible? If so can someone kindly lead me step by step? If not, what are my options? Thanks in advance.

Hi,
there are two means of reversing an axis motor.

1) Software setting: Config/Ports&pins/OutputSignals check (or un-check) the ActiveLow of the Dir signal only of the axis motor
you wish to change.

2) Reverse the motor: The motor windings are two pairs of wires, phase A, A+ and A-, and phase B, B+ and B-. Swap just one pair,
say A+ and A-, at the driver. That will cause the motor to go in the other direction without having to change the ActiveLow/ActiveHigh
status.
