I recently had a MOC where I wanted to do something similar (only 2 axes
though). After spending a little while on it, I gave up, and just moved both
axes at the same speed until both reached their target. Means they usually
arrive at different times, but as it was only a minor part of the program, I
decided that was acceptable. I may go back and revisit at some stage.

That sounds like a sensible solution.
Play well,
