Andy,
Just curious since we have the same harmonic drive and STMBL for the 4th axis
what max velocity and acceleration are you using.
I just checked, and the numbers are very modest. 100 deg/sec and 250
deg/sec accel. But the TP will always hit the programmed endpoints
regardless of accel settings, as it calculates within them.
I don't see the issue that Gene reports because I never home the
rotary. There is no point as I have no indexed workholding and there
is no need for soft limits.
If I need to align a part, I do it in the usual ways, with indicators
and probes, and then touch-off for alignment.
I could do that too, but then I couldn't carve screw threads. Now I can.
Cheers, Gene Heskett.
