Title: Issues getting Stepper Motors to move with Pokeys57CNC
Post by: alton.carroll on October 17, 2018, 03:23:11 PM

Okay...I am not a newbie to CNC machines, but I am new to PoKeys and Mach4. I also opted to buy Polabs stepper drivers because they were Ic2 capable. Here is my configuration followed by my issue.

Controller: Pokeys57CNC
Stepper Driver: Postep60-256
Software: Mach4 (V4.2.0.3804) Pokey Plugin (V8.49.0.3813)
Power Supply: 24v (Controller Board) 36v (Stepper Drivers)
Spindle: 1.5Kw (Hyoung 120v Inverter)

Stepper Motors:
    X-Axis: Nema 24 / 425oz
    Y-Axis: Nema 24 / 425oz
    Z-Axis: Nema 24 / 425oz

Home / Axis- Switch:
    X-Axis: NO Mechanical
    Y-Axis: NO Mechanical
    Z-Axis: NO Mechanical

Limit / Axis+ Switch:
    X-Axis: None
    Y-Axis: None
    Z-Axis: None


What I have done so far...

On my first run I used Pokeys configuration and used the limit switch wizard to set the inputs; closed Mach4.

I opened each Postep60 driver with the software and set-up the driver, and ran them via the software, so I know that they are wired properly.

I restarted Mach4 and opened Pokeys plugin and inverted E-stop in Pokeys Plugin.

All seems well when I jog the axis (DRO moves), but the motors will not move. There are no warnings or limits activated.

Any ideas where I go from here?

I got it fixed...this forum is great didn't even need a reply to get the answer.


Just in case you are having the same problem...

1. Check ribbon connectors
2. Try to invert the enable output in Mach4
