I have these items:

Syil Super X3 CNC
Bobcad cam
mach 3

The issue I am having is when I use the Mach 3 with the Mill. It does not respond to any inputs. No G-code makes any movements on any axis. The mill is on, and is on CNC mode. I have an IBM thinkpad that I use for both programs, this shouldnt be the issue. Has anyone run into this problem?

I really need to get this thing milling stuff asap!

Note: mill has never milled anything out, its still brand new. When the mill came, there was the circuit board laying on the milling surface. I took the back plate off and installed the circuit board onto the back of the mill. Maybe there are items there that are not connected?
