    Re: looking to upgrade steppers & drivers.

    Here's where I'm @ driver is 3.5 amp micro stepping set to 1/10 or 2000 steps per revolution, 2:1 gear reduction gear heads running on a 14.5 pressure angle 24 pitch R&P with a 24 tooth spur gear with a OD of 1.083"

    I told the axis to move 16" and it moved 41"

    16/41=0.3902439 and divide Pi by the gear ratio? 3.14/2=1.57 so 0.3902439x1.57=.612682

    I see you have your gear ratio set to 5.0 and your screw thread is .31833

    Check the settings on your stepper driver, from the distance moved and your other entries it may be set to 4 microsteps per step instead of 10.

    If your rack and spur gear are 24DP then the pitch diameter is 1" or pitch circle of PI for a 24 tooth spur gear.

    So the screw thread that Torchmate or Flashcut wants is Screw Thread = rack teeth per unit length/ tooth pinion = (24/PI)/24= .31831, mine is not set to the theoretical number because that is how I fine tuned my motion.

    Check and fix the settings on your stepper driver or enter 4 microsteps per step in the Torchmate or Flashcut SW.

    Mine worked by the book for getting close. I measure the gantry movement with a dial indicator then and adjusted the screw thread number until 1" commanded gave 1" on the indicator.
