Well, sadly, the 13.03 can't even open the USB port. Here's the whole log: (remember, the 12.12 version on this same machine opened the port, uploaded the firmware, and ran the "first run" wizard with no problems) Changing monitoring state from 'Offline' to 'Detecting serial port' Serial port list: ['/dev/ttyACM0'] Connecting to: /dev/ttyACM0 Error while connecting to /dev/ttyACM0: 'Timeout' Failed to open serial port (AUTO) Changing monitoring state from 'Detecting serial port' to 'Error: Failed to autodetect...'

This is exactly the problem I'm having also. My log looks exactly the same (see attached). The "First Run Wizard" works fine ... it uploads the Marlin firmware, then runs through the limit switch checks and head heater tests just fine. But - cannot connect the bed-leveling wizard. I figured ... what the heck, just level the bed manually and try to print. This turned out to be a very bad idea. It does not "home" the bed and printer head, but instead, slams the head into to stops. Had to yank the power cord to avoid disaster.
