I have a small lathe that I set up to use a servo drive on the spindle, essentially making the spindle a rotary axis. The servo was large enough to provide the torque needed to make the cuts and it made coordinated spindle moves wonderfully. (think thread cutting, cam grinding, milling cutter relief grinding etc.) The only problem was that there was no simple way to set the spindle back to zero degrees WITHIN a program without actually "unwinding it". I searched long and hard for a solution and was finally convinced by those who know a lot more about the workings of the trajectory planner than I (which would be anything at all) that it can't be done for the reasons just explained.
By the way if there have been any changes in LCNC that let you "home" or set the rotary axis back to zero without exiting the program or actually running the axis back to zero I'd like to know about it since I haven't looked into it for over 10 years.
