@foosel, Is this an open() timeout thing?

from stopit import SignalingTimeout as Timeout

with Timeout(5.0) as timeout_ctx:
    with open('/nfsdrive/foo', 'r') as f:
        # do something with f
        pass

I cannot seem to post the entire log I get this message Whatever that means....
Sorry, new users can only put 2 links in a post.

Bottom line is the printer is changing states to printing. I suspect that it is in the gcode viewer or the analyzer. But at this time it is only a SWAG
