FAQs / Mach 3 stepper control issues

« on: June 26, 2017, 03:30:38 AM »

Hello,

I am setting up a CNC control setup for a denford branded sherline mill. I am  unable to get the steppers to move with Mach 3.

Here is my setup:

PC-to-route m2 BOB board:

And gecko 201 stepper drivers

I am using 2Amp 24v stepper motors made by Sanyo Denki

I am running Windows xp on a Sony vaio desktop with parallel port.

So far I have confirmed that my bob is talking to Mach 3 by triggering limit switch inputs but am unable to get it to move the steppers.

As far as I can tell my wiring is correct based upon those data-sheets and the steppers are powered as they have holding torque when the drivers are on.

Thank you for any help!

Here are some photos of the setup:
