    Stepper Motors

    I have a Xylotex 3 axis board with 4 wire steppers (Nema23), Mach3, XP Desktop, HP 20.7" flat monitor. When I jog my motors 4 inches, the Mach3 DRO shows 4 inches but actual travel of my mill table is only about 3/8 of an inch. Motor tuning is:
    Steps Per - 2000, Velocity 175, Acceleration 25 and the Pulse - 1 and 1.ted. Thank you,


    Suggestions appreciated. Thank you,


    Ray

    What happens when you up the "steps per" by a factor of 10?

    Re: Stepper Motors

    Is it lead screw, belt drive, rack and pinion?
    What's the gear ratio of the system.
    The default Xylotex setting is 1/8 microsteps, or 1600 steps per stepper revolution. So I doubt 2000 steps/inch is the right number.

    Also, set the pulse widths to at least 2 or 3, instead of 1.

    And make sure the Mach3 default native units are the same units you are using.
