Guys not sure if this is the right place to post this but I use Mach 3 for my machine.

I have a small rectangular shape that I need to pocket on different places on a part (which is not big deal, just Zero at the new location every time) but I also have the need to rotate it 90 and 45 deg at times.
Other than making code for each variation, is there way to do it from one G-code file? - I don't think so is there?

Thanks

You can use G68 to rotate the coordinate system.

Thank you. I will look in to that.

So what I found is that the syntax is:
G68 X0 Y0 R (angle).

The question is, where does that line go And does it need to be terminated?

It seems I would need to just edit my code every time. Good tip but I can't get it to work.

My X and Y dros turn red and g code disappears from the preview rather than just rotating. Do I need to reference/ zero the axis when i do this?

The Red DRO's tell you that the rotation is in effect.
Try regen the toolpath to see the effect.

You place the line when or where you want to rotate the g-code.

The X and Y coordinates in the G68 line are the center of the rotation.

To disable the rotation, use G68 R0.


Whether or not you need to re-zero depends on exactly what you're doing, where your pocket is programmed at, and where you want it.

In order to use this, you'll need a very good understanding of g-code, and exactly how this works.

Your other option is as you said, make separate code for each different thing you need.
