I've done 4th axis, work offset macros, just curious if anyone has done dynamic work offset macro?

Yes. There should be some threads on the site detailing the concepts.

Where to find them?

I've already got that I calculate against the set work offset. By dynamic I mean as the 4th axis is turning constantly updating the offset. I guess G54.2 does it so I'll dabble with that some time.
Just curious if it can be done with a macro on a machine that doesn't have the option?

I've worked on a program to do this on a 4 axis vmc. It can be done but was not accurate for my needs. If my rotary and fixtures were more square to the machine I think I would of got better results. The problem is I work in an enviorment with other machinists where things get crashed fairly often.

Many years ago I worked at a place that I think did it, I never paid too much attention to it then, we entered work offset info in the macro instead of the work offset page.
