Got IT!
All else fails - READ the screen!!
On the line to the right of - and next to - the "Reset" button - the message "External emergency Stop requested !!" Duh?
With nothing attached ..... I certainly was not expecting that or looking for it - but sure enough --- when I checked "Pins & Ports" down in the bowels of the pin set up - the Emergency Stop input was the only input assigned and active by default - to some arbitrary pin. Deactivated and applied the new configuration and the problem went away. We shall see if it comes back when configured for my externals. It's probably based on a "normally closed" -- "emergency stop" loop and with nothing attached to the port - it's "open" and calling for emergency stop.
Isn't that special! "Greetings Professor Artimus, Would you like to play a game?"What threw me ..... this didn't happen on another computer (a laptop) that I setup just for reading and browsing the Mach3 app while in my recliner!
But .... when I installed it on the desk top PC I've designated as the CNC control machine with a real LTP - it did something a little different. Not sure why - defaulting the emergency stop loop input to "ON" is probably not a bad thing ... to avoid legal problems at best - prevent a few truncated digits at worst!
OK so now - tomorrow - if I can find a cable - we will connect this tired old PC to the new Chinese
BOB (Break Out Board - took me a while on that one too!) and see if we can make a few lights go blinky blink!!
I hate it when I start answering my own questions!
And did I say I found a really neat, kinda basic, g-code generator - F-Engrave (Windows) --- gen'd up some quick and simple g-code files just to play with with on Mach3. a FreeBee to boot.
Hang in there CNC'ers.
