Steve,

I purchased the PMDX-122 as suggested I have everything wired up and I have the pins set in mach3.  The steppers are engaged, but I am not getting any movement from the jog functions in Mach3. Any further troubleshooting tips?

Thanks,
Lewis

Thank you for the reply and the valuable info! Yes, the fourth axis is a Sherline setup.  I think for now I will use it with the Sherline controller and if I decide later to use it for full 4th axis work I will get another stepper.  I will be using Mach 3 software.  I did see the pre assembled controller.  It is definitely an option at this point but I wouldn't mind getting my hands a little dirty.

Thanks again,
Lewis

Hello all,

New member of the thread just joined yesterday. As of a couple of days ago I bought a new Sherline mill with a bunch of accessories and almost everything to convert it to CNC. I would like to purchase the rest of the components from PMDX but I would like some help.

With the Craig's List purchase I received:

3x Sanyo Denki Step Syn (Nema 23) Stepper motors, 2A DC 1.8deg step (103H7126-5710)

3x RTA Pavia 24-45 VDC (CSD02.V) stepper motor control boards.

The machine also came with Sherline's 4th axis and controller

I posted a similar post on the CNCZone.com forum and received a response suggesting I look into PMDX components, which brought me here...

My dilemma is the mind blowing array of breakout boards available. If anyone could please recommend the necessary PMDX components (breakout board, power supply, etc) that will interface with the components I already have (listed above) to complete the CNC conversion of the mill I would be very grateful!

Thank you in advance,
Lewis
