Thanks Tony, I just tried a variant. Uninstalled Mach3, deleted the directory, deleted the desktop shortcuts but didn't go into the registry. I've used regedit before but it helps to have some idea what you are looking for and where. Anyway you said that didn't help?
So I verified good communication to the DMC-2160 with ST, set IP addresses and such and got the ethernet link working. I have commanded motion, encoder counts and limit switch indications so good there I think. The ENET link is registered.
Reinstalled Mach3 and the Galil plug-in (That's just a .dll file with the .m3p extension added on right? Probably contains an installer?)
So Mach3 starts and the bottom message bar says something about Galil now being connected, with the reset flashing. That may be after opening the config window, configuring and choosing the galil. That message goes away when I push the reset button. Then I've got nothing. No limit switch changes, no encoder counts, no motion, no port or pin numbers.
I keep thinking there's something very minor that I'm missing here.
