4th axis
« on: August 07, 2014, 05:11:35 AM »
I have a servo motor with 1000 line encoder and a 20 teeth pulley on the shaft connected to a chuck with a 5mm pitch belt and a 60 teeth pulley that rotates to a ratio 3:1
my question is what are the settings in mach 3?

33.333333 steps per unit (degree)

1000*4 (quadrature)=4000,*3 (pulley reduction)=12000, /360 = 33.333333
