It's working ok now. I restarted the machine & Mach and did some other button-configurations in the meantime.
Here is the configuration I'm using for PoKeys55T MPG:
1) In Config->Ports & Pins ->MPG config;
1a) enable, A-port = 10, A-Pin = 1, B-Port = 10, B-pin = 2
2) "Plugin Control"-> "PoKeys Conf" -> "Use Encoder5 - MPG1" is checked
After that it seems to work OK, albeit little slow. I can't judge yet how actual milling machine will perform,
since I'm running Mac OS X and on top of that VMWare virtual machine where the Mach3 & PoKeys is run in the Windows-machine. There might be some
lag issues due to my machine setup. As soon as I wire the rest of the buttons & configure the PoKeys, I'll transfer the setup to the actual workshop-machine.
With best regards & Happy New Year from Tampere / Finland,
