You bring up the "calibration" menu, and change parameters while jogging and looking at the scope traces. When the error is small enough, you save the settings to the ini file, and they are used from then on. > If later on I wanted to sync the spindle, would it do it? Yes, I was doing this at the recent NAMES show, although on a mill, but I put threads into bar stock in the spindle. You can change the spindle speed while it is threading, and it will follow the spindle speed precisely.
