Thank you for the clear explanation.

What are you meaning by the Gearbox/belt = 9? is that a reduction of 9?
Without any gearing then 1 rev of motor moves 1 inch, one rev of motor is 2000 pulses (500 x 4) so that is what your steps per unit will be.
 If you have a 9:1 gearing then it will need 9 revs to move 1 inch so Steps per would be 2000 x 9 = 18,000.

General Mach Discussion / Calculating Step For Mach

« on: September 08, 2008, 03:17:18 AM »

I like how to calculate the step for Mach when using step motors. I plan to build another new machine using servo motor and gear rack.

The equipment would be like this.

Servo Motor RPM = 3200
Gear Rack = 20 DP
Pinion = 20 Teeth
GeckDrive = 320
Decoder = 500 CPR
Gearbox/belt = 9

I think that is everything I need. How do I get the steps for Mach?
