Cura 2.6 beta and UM3: Print start hangs at "Heating Print Core"..

[sfwright 0]

I just migrated to Cura 2.6 Beta. Running an UM3. When using gcode from 2.6, has anyone noticed the start of their prints hanging at "Heating Print Core"? Self-leveling works fine. Bed heating is also fine. When in the heating print core routine, the bar meter runs almost to the very right edge and hangs there indefinitely. I can examine my temperatures in Tune mode and all looks okay - both bed and core running at the desired setpoints. The software has not locked up either. Any suggestions would be greatly appreciated. Thanks!

I'm looking into this problem. Can you tell me the firmware version number on your printer?
