Also do you know for sure that UCCNC displays connection lost message and doesn't just throw a Generic E-stop message if doesn't fully lose connection.?
Well during large noise problems (tried unshielded vfd wire) uccnc looses connection with uc300 and can't be reset without disconnecting usb and reconnect.
That is way worse then e stop.
Now when it e stops I can just reset, run spindle and then start cycle again.
But for every time I do so it will run a shorter time before it e stops again :(
