Hi i just bought new cr5 pro, after initial calibration tried to print the demo file - which printed ok. Then i tried to print some of my own files sliced with the boxed slicer - all was ok. Next day when i tried to print any file demo/my the printer prehets bed and extruder but does not start printing. Looked up for fw for update but it is not listed in downloads. Tried recalibration - nothing. Rebooting - nothing.
