Hi, Jack
The Abnormal Condition flashing doesn't mean there is anything seriously wrong most of the time it's just a warning that your start-up conditions have been changed,
In your example, What set it off is your default (Normal Condition) was set for CV Mode G64, The new code your running has a G81 (Canned Drilling) cycle in it and the G80 isn't canceling it out because it's not in the Pre-Amble code issued by your Rinocam Post at the beginning of your G-code.
You'll find allot of inconsistency's in most all post processor programs out there. All this stuff is confusing in the beginning and I'm not sure weather it ever get's any better over time.
Try this G-code:
G00 G49 G40.1 G17 G80 G50 G90
G20 G64 ;"G64" Need's to be added in your Rinocam/cad Post

Edit: You could put this in Mach3 General Configuration, Initialization String "G64" Also.
If you Double Click on the Abnormal Condition button you can re-set it to Normal, It causes more trouble than it's worth anyway.
