Not printing... wrong settings?
I wonder if there is a glitch in the firmware producing this unexpected result (which I think I also observed).

If you navigate to quick settings you should find preheat pla. Selecting this has little obvious effect (except for fan speed droop as the heater kicks in), but the target temps will now be 190C / 60C.

Print File seems to wait for the pre-heat to have reached a threshold before starting to run.
