How far off is it? High low what? Are you certain of your screw pitches? ----- Original Message ----- I have just switch my mill over from linear scales to rotary encoders and I can't get my input scale right. OUTPUT_SCALE is 1, Units-inch
X axis has a 1250 CPR differential encoder, motor 14 tooth gear, screw 21 tooth gear, .200 pitch screw. 1250 X 4 X 1.5 X 5 = INPUT_SCALE = 37500 Y axis 5000 CPR differential encoders, motor 14 tooth gear, screw 21 tooth gear, .200 pitch screw. 5000 X 4 X 1.5 X 5 = INPUT_SCALE = 150000 Z axis 5000 CPR differential encoders, motor 14 tooth gear, screw 28 tooth gear, .200 pitch screw. 5000 X 4 X 2 X 5 = INPUT_SCALE = 200000 If these calculations are correct they don't work, to even be in the ballpark of one inch of actual travel (+/- .020) equaling the DRO showing one inch I need. X axis INPUT_SCALE =38500 Y axis INPUT_SCALE =750000 Z axis INPUT_SCALE =1000000 What am I missing here.
