Need some help with some math. Not your normal situation going on over here.

Ok, I got GT2 belt, 16 tooth pulley going to a 60 tooth pulley that is connected to a 16 pitch (24 tooth, 1.5 inch pitch diameter) spur gear on a rack and pinion setup. 1/16 stepping, 1.8 degree motor.

1 step divided by 159.11 inches = .00628 inches per step.

which is .1595 mm per step

Im looking for steps per mm so- 1/.1595 = 6.27 steps per mm

6.27 x 16x microstepping = 100.32 steps per mm

Yeah, current steps/actual distance=x steps/desired distance is what I will do once I bring my dial indicator home, just wanted to do the math and see how close it comes up. Ive laser cut my own rack and pinion setup and want to see how accurate it is coming out. Almost got a new machine up and running.
