Yes. Everything looks as though it should work, but when I open Mach 4 it says "UC100 not found". The blue/green lights are all on, but cannot enable it. Had an electrician friend stop by and verify I don't have a "ground loop" as was suspected by Arturo from CNC4PC.
The new UC100 should be here by tomorrow, so hopefully it is just a bad unit.
I'll keep you posted.
Thanks for trying to help.
