Hood,
Yes, I use probing quite extensively. I've zeroed out all those filters. Brian helped me get the spindle going. I have a VFD, so the spindle control is two relays and a PWM. The PWM was the problem because I hadn't set the motor tuning for the spindle axis. But I completely don't get the relevance, or meaning, of "Steps Per" and "Velocity" for a PWM spindle.....
The Z axis is still backwards, and both Brian and Greg are scratching their heads over that one.
Meanwhile, I finally got motivated to finish up the last few nits to get the KFlop going using their CNC controller app, and I believe it's now ready for prime time. All seems to be working properly now on that front. I think tomorrow I'll take it out for a maiden voyage, and see how it goes.
Regards,
Ray L.
