Curious what the going rate for used grex's is.
I've had mine in my power enclosure for a year or so now and except for using it way back with the first mach plug in's I have not had the time or desire to keep up with the learning curve getting it back up and going with my 2 machines.
Thus it's pretty much sat there while I've controlled with parallel port.
Today with my VFD added I needed to make room in the enclosure for my parallel port relay control to turn my spindle on and off. So out came the Grex.
Did get it loaded with the latest programs for mach before pulling it and got communication with mach and all. So shoudl be in good shape.
Got it in the first place to cure some issues which I thought were parallel port problems with my new mother board. But ended up a simple bios issue was causing it..
