Gerry, that's what I'm thinking.... although i'm happy with GREX G100 and it's awesome, i do notice that it is a pain to run with Mach3 and some things don't work. I'm not able to do auto-tool zero and reffing all axes at the same doesn't work. I have to ref X, Y, Z individually.

What other controllers are good out there with a lot of support?

I'd like to use an ethernet port so i guess Ethernet SmoothStepper is my only choice, right?
