In Spindle S True window I have all the time wrong reading of the speed, Much applies some kind of ratio to true RPM, don't know how to reset it.
In Spindle Calibration and Testing dialogue box the reading is correct (while the box is open Spindle S True shows correct reading as well, but as soon as box is closed S true jumps up). I can see that Pulses per Revolution box is showing 1, I know that there should be 0 because I have only 1 cut in a disk, but can't change 1 to 0 whatever I tried.
Please help
