Losing steps/position, again

[ngwagwa]

I have a video, but it's fuzzy and noisy... but if it helps I'll throw it onto YouTube. But, I think I can describe it easily enough:

No comms: Green power light on board, green carrier light as one of the two integrated LEDs on the RJ45 socket.
UCCNC starting up: Blue light on board illuminates. Orange activity light in RJ45 flashes 3-4 times a second, continuously.
UCCNC operating: As above.
UCCNC shutdown: Blue light, and orange light extinguish.

Thanks so there is a light on next to the RJ45 socket with no comms but it goes off after running and exiting UCCNC?
