How do I get the proper ratio to calibrate my newly retrofit cnc router?
When I run multiple cycles, the Y axis seems to move over a little each time, and after a few cycles the parts are out of tolerance. J.P.(group)

Is this a stepper machine? If it doesn't return to the same position, it's losing or gaining steps.
I have a servo motor system, with encoders mounted directly on the motors.
I recently had our multicam router retrofit with a camsoft software setup. I need to find out what the ratio is between the servo motor, and the rack and pinion gear setup, and also the motor and the ball screw. I need to know how many encoder pulses it takes to move 1 inch. Any ideas?
I'm thinking a caliper and some trial and error to get your best fit there, the gear pitch and ratio was probably specific to the old software (if it came with the router, I'm assuming it did) especially if it's an older model before ISO standards. You may have to fudge the programming to get it to run the way you want it, too.
oh, also you can try the data sheet for the specific servo model. Contact either the manufacturer or any other supplier, google search etc, but then again it depends on the length of the pulse input via your software (which you'll need an oscilloscope to measure).
