The actual spindle speed does not mach the m3sxx command in the MDI terminal
Where do I get the pwm rate from?
I have the bob in the picture (If it is needed for determining the pwm rate entry in the stepconf spindle page ! )
question 2 for calibration:
do I need to measure the 0-10 volt and if it is for example 1 volt, then for calibration I enter pwm signal as 0.1 and take the reading from the spindle vfd of the speed say 40 herts = 2400 rpm
and the second point for example 9.8 volt means pwm(The maximum the bob gives) = 1 and the rpm is 24000 rpm for the second point.
