Ok connected my computer to the controller the other day (Novakon NM-135 mill), loaded provided profile (Mach3Mill.xml) but no workie.

1/ Computer is running XP and connects to the controller via LPT1
2/ Mill is in a running state (no etop etc), table and head are nowhere near the limits
3/ Mach 3 diagnostics input signals behaving very strange though. I have M1/2/4Homing yellow signals intemittently blinking sometimes not blinking for 20 seconds then would blick 2-4 times then stop blinking. Emergency red LED would blink intermittently as well.

Clicking Reset button does nothing and does not reset.

Any suggestions on how to troubleshoot the connection?

Well, if you don't have any other programs running....I would check your parallel cable...it could be intermittent.....do a pin to pin check.

Does the Novakon have a breakout board built into it?

Sounds like you have noise on your switch lines.
