    Hi Guy's I need some Help Please?

    I'm having a problem with my Z Axis motor tuning . The settings are listed below. It goes in both directions when I use either of the Z+ or Z- tabs. Have any Ideas on what I'm doing wrong?

    The wiring has been checked and double checked. I'm running the jog rate at 45% and it keeps going in one direction and then reverses the direction. If I run it at 100% it does nothing.

    I listed the settings below

    I'm using M542 drivers.

    * Manufacturer Part Number: 23HS45-4204S
    * Motor Type: Bipolar Stepper
    * Step Angle: 1.8 deg.
    * Holding Torque: 3.0Nm(425oz.in)
    * Rated Current/phase: 4.2A
    * Phase Resistance: 0.9ohms
    * Inductance: 3.8mH+/-20%(1KHz)

    You don't say what the voltage of the power supply is that feeds the drives?
    The more you know, The better you know, How little you know

    It could be your Keyboard.!! . . . .Try another. I've had this type of thing happen before and it's been the keyboard related.

    If that doesn't work and your 100% sure your wiring is ok then Re-install Mach3. Also if this is a Dodgy copy of Mach3 that came with the BOB then dump it and download the latest Lockdown version from Artsoft site.

    So I was using a Logitech wireless keyboard and just switched it to a direct USB plug in keyboard and it works fine.

    Thanks for the help Guys.
