    I got my Ethernet SmoothStepper the other day and I'm having trouble getting things to work right. I'm using a Geckodrive G540. Can anyone help me with the base frequency for the PWM & the step and pulse width settings?

    Update: I found an install & configuration instructions on crcrouterparts.com's web page and followed them step by step. I now have motor movement. HOVEREVER, X and Y axis motors are slow and "grindy" (if that's a real word) I've tried the motor control in Mach3 and the trim on the G540 controller. Nothing will smooth out these motors. The Z axis is smooth and quiet. Could anyone please help smooth out these motors?

    What size power supply are you using?
    Do you have the inline resistors between the g540 and motors?
    You may want to post this over in cnc mills/Routers.

    I think it's a 24VDC. It came with the kit I bought. Resistors in place. I hooked it back up to the XP desktop and it runs fine. But with the laptop and Smoothstepper problems return.

    It's a 48V power supply. Mine is a 7.3 A. I understand I need a 12.5 A. to run 4 steppers. My system worked just fine until I added the Ethernet SmoothStepper. Now all of a sudden the NEMA 23 steppers are running hot,slow and rough. So can anyone explain why things changed by adding the ESS?
