Sorry, stupid problem. I had a thumb drive in the machine and I was looking at
the files on the thumb drive.
The files on the machine had been overwritten when I installed 2.9.0Pre. I
copied the correct files over and
cured the problem.

Also it's possible that your PID is limiting the responsiveness, or

Gene,

one other clarification, on page 13 of the html docs for PID:
pid.n.tune-type u32 rw
When set to 0, Pgain,Igain,Dgain are calculated
Whwn set to 1, Pgain,Igain,FF1 are calculated
But what is the more common "type" name? Position, Velocity?
and which is preferred for stepper

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
