Noob needing a hand to trouble shoot what’s wrong with my machine.

Info

Syil x4
Mach 3

Was working fine up until moving it. Since reconnecting it to the pc - the pc has no control what so ever, as if the the cords not connected.

I have
- Checked all boards have power with a multi meter
-checked the ports configured
-checked the parallel cable is plugged in, checked continuity of cable and replaced the cable
-replaced the pc (was on it way out anyway)
-I jumped the COM and FWD pins on the inverter and the spindle starts (sunfar E300)
-checked the diagnostics screen for life and no limit switch’s show, e-stop doesn’t show, is literally as if the machine is not plugged into the pc
-Just ran the “config check” in Mach3 and seems “output 7” is configured wrong?

Have read through a heap of threads but am really quiet clueless where to start looking, any input would be greatly appreciated
