Title: Rotate A Axis via Macro Code
Post by: MRM RCModels on March 03, 2013, 07:14:17 PM

All,

I'm writing a lathe turret tool change macro and am having a hell of a time finding a way to rotate the A Axis via a macro function. The A Axis Stepper is controlled by a G540. I would like the stepper to rotate freely if possible (like it was jogging).

Thanks

Assuming A is defined as a rotary axis:

Code "G0 An.nnn"
while IsMoving()
    Sleep(10)

Where n.nnn is the angle to go to should do it.

Thanks Ray. How do you stop the rotation? I need the axis to rotate while searching for the next tool change then stop.

If you want it to just continue rotating until you stop it, use JogOn() and JogOff().  Download this:

and it should answer all your questions (I wrote this about 4 years ago...).
