found a way to turn it off............
Enableyour X and Z axis under ports and pins, Enable your Enable 1 also.
Enable output6.
run some code.....
Watch the Output six, it turns off and stays off..........
You must have has a "Hung bit", sometimes if you have a screenset like that nice "Practicle lathe set"........hehehehe
and your playing around with things like VB, or Brians or somthing. Sometimes you can Turn on a signal, i.e. OUTPUT6, but for what ever reason, you never send the deactivate signal to it. and you may have then disabled OUTPUT6, and you close mach. Mach saves the states of the LED in its config. When you come back up, the LED is blinking..(on). It has never been turned off and since you disabled the output with out first turning it off, it hangs...........
If all your axis are disabled like the xml here, then you force mach into sim mode........
Once you enbable all the above and run a little code, it resets the bit where it should.
At least that is my theory, It sound good any way, but could be full of Crap also, but what ever the case, that fixes the prob here on my comp.
