Hi, Wes
I won't have the access to my machine by Monday to give you exact settings, but will try to guide you by heart.
0. Check that you have the latest version of the plugin. I would suggest downloading and installing Beta software 3.0.39 from poscope.com. It contains the plugin in the setup.
1. Don't use PoKeys software for anything else than diagnostics. You should use Mach3 plugin to configure all functions (when Mach3 plugin loads, all plugin settings are transferred to the device!).
2. Enable MPGs you want to use in Mach3 ports and pins configuration (as you have done already)
3. Setup encoder inputs in plugin mapping settings (as you have done already)
4. Setup encoders in Encoders tab as mapped to DRO MPG1, MPG2, ...
5. Enable PoKeys to handle MPG jogging (there should be a check box at the bottom of the 'Encoders' settings page
