General Mach Discussion / Re: Spindle calibration, how I manage to get it working
« on: September 20, 2016, 06:43:41 PM »Yet another update:
Spindle calibration works fine in MILL mode.
I am still having a few issues in LATHE mode. I usually have to issue a spin command twice to get close to the calibrated spin, otherwise it runs faster - sometimes a little faster, sometimes a lot. Sigh.
The comment was made somewhere that there is little difference between spinning at 1500 RPM and 1600 RPM. This may be so on a Mill, but on a Lathe it can mean the difference between sitting right on tool/part resonance and being way off resonance and quiet. Mumble.
Cheers And Happy New Year

The spreadsheet is excellent and has done a great job of calibrating my lathe spindle speed. I have the same issue that you have regarding having to request the spindle speed twice. Did you ever find a fix for this?
Thanks davidimurray, good to know the spreadsheet was useful to someone!
Sorry I haven't been checking this post for a while...
You know, this need of setting-speed-twice have been annoying me too. Sure it is not the best way to use workarounds, but the info you guys posted really helped me to make it work!
Cheers!
