So I heard back from the vendor. He sent me some old Mach3 software that is probably bootleg and doesn't run anyway. Throws "INTERNAL ERROR B109-13: Cannot decompress setup program". Probably corrupted, or the Chinese language it's in is freaking my PC out.
I'm thinking about just replacing that board with one that's supported properly. And I still haven't bought the software yet (was trying to get the stupid thing to work, then play with mach3 mach4 CNCUSB and BobCAD and decide what to go with). This little $700 toy is getting expensive.
Anyway, suggestions on the board replacement?
