Hey Guys,
How did any of you calibrate/verify your Boss spindle speed? The reason I ask, is that the small round screen-printed plate that denotes the spindle speed is not keyed. It is simply held in place by a small acorn nut (by friction). I removed mine early-on in the retrofit process, and now have no idea what speed the spindle is actually turning. I do not have access to a tachometer or a stroboscope, so I need some other options.........or a suggestion as to where I can rent one of the scopes.
I am really not too worried about the plate being accurate. I am more concerned about my Mach2 software readout being in sync with the spindle speed. If I could measure the actual spindle speed and use the Mach2 input speed, I think I could calculate a pulley ratio to compensate.
Thanks,
Wayne
