Hello, I haven’t printed in a couple months and fired it up again today and get the message: The printer has restarted or lost power  
This happens when it is about to due it’s 9 point calibration. Here is the last few messages of the console log:  
\< [17:47:59] echo:busy: processing

\< [17:47:59] T:139.77 /140.00 B:52.44 /60.00 @:13 B@:109 W:1

\< [17:48:12] The printer has restarted or lost power.

\< [17:48:12] Closing the USB printer connection.

Anyone know what this may be and what I need to do to fix it?
