nanoDLP

Hi,
Build 1149
The printer finished the print job but it seems the Arduino board stopped receiving commands from the Pi during print. Unfortunately I don't have a debug file after this failure but here are the log file after restarting the printer.

After a few restarts the printer start work normaly I don't know if this related to nanodlp or this is hardware issue?
