I suggest to print or mill or laser every time from the touchscreen.
I guess you did it over the air?
I am not sure and guess, the feature about ongoing printing while connection loss from luban is pretty new, maybe this is still buggy…
Printing over luban is not the recommended way (except 5minute prints for me) because if your pc does updating or goes to sleep mode this cause the print to stop and abort (this was the case in the past, the new feature may corrects this but was not advertised and I did not test).
