Lets say after drilling #3 hole and I need to go back to #1 position,
What code is needed to make the stepper turn back, CCW, to #1 position ?
This is my first attempt at Cnc and Mach3.
All is wired up on my bench.

G90 is absolute, wouldn't it be A0?
G91 -45 if relative?

Ive typed G90 A0 and G91 -45 in MDI, the stepper still goes CW. but the ref counter 4 goes to 0 (zero)
Sounds like the step is working, but the dir signal is not changing?

In Ports/Pins- Motor Output
A-enabled, Step pin 8, Dir pin 9, Dir Low ckd, Step Low ckd,
Step port 1, Dir port 1.
Is this relative?
May have to monitor the status of the pin, either at the PP or at the drive and see if it changes with direction?

There are a couple checkboxes in General config that mat need to be changed. Something about rollover (don't have Mach on this PC)

Under Ports/Pins>Motor Outputs>A axis, I changed Step Low Active to Disabled and it worked.
Dont understand why it does this.

I have cheat sheets w/ all G and M codes.
and by modal groups.
But is there any reference for definitions in understandable terms?
In Gen Config>Rotational there is Rot 360 rollover, Ang Short Rot on G0 and Rotational Soft Limits which is ckd by default.Originally Posted by ger21
