Sam, dammit, you are having too much fun while the rest of us are more or less locked up. But it shows others what LinuxCNC CAN do, so I love it. That said, in low gear, my spincle encoder scale is a bit over 14,000, so I ought to be able to do some of that too. If I can con it into going that slow. Since I have 2x the nameplate FLA to hit that motor with, I don't see why not. 1st step is 100 rpm in high gear, and its still turning ar 15% on the slider, I'll bet it can do it in low gear. Gotta get me a boring head athough I see you aren't always useing one. Gotta put a range switch on the tach, its sorta difficult to see 10 rpm on a 3000 scale. I wonder just how far I can push PGain at that sort of speed, its plumb stable and silent at 20 right now and just a bit shaky at 40. I have said for a long time that there isn't anything that LinuxCNC cannot do and things like this continue to prove it. I hope all those guys using Mach on youtube are dying of jealousy.

I do it occasionally, so have you, but Sam seems like he does it a lot. And all of us benefit from this lists ability to answer the questions generated by our wildest dreams.
