Finally got this working.
At Kenny's recommendation I updated the firmware to the latest version. This can be a bit tricky as it resets your Galil card when you update firmware which is typical when updating firmware. Kenny talked to one of the guys that helped write the Galil plug in and gave me a very nice/easy way to update the firmware and retain your settings. Here's the process if you need to update firmware.
1) Download and run DMC Setup.
2) Using DMC Setup upload your .dmc settings to a location on your computer.
3) Download and install the new firmware.
4) Download the .dmc settings you previously saved
It's that easy!
At that point Mach3 quit locking up but still wasn't functional. Kenny recommended that I verify the data record was accessible. I verified that it was so then started poking around to see what I could find. I found an entry in DMC Setup called Echo that was set to off. Knowing I had a communication issue I thought it worth a shot so I changed it to on then wrote the settings to the E-prom. At this point Mach3 started functioning perfectly. To be honest I don't know that this is what fixed it because I have no idea what Echo does...it just started working so now I'm completely up
Last thing I'd like to note; I'm absolutely amazed by the assistance Kenny gave me. He's on the other side of the country and doesn't benefit in any way if offering his assistance. He spent several hours on the phone with me, not only helping with getting my machine running but also educating me on servo's, Mach3 features, limit switches, home switches.......just an absolute wealth of information. He was away over the weekend but called me back Sunday night just to check in and see how I was doing.
Thanks so much Kenny, you saved me hours of what I'm quite sure would have been intense frustration.
