I have tried twice to do the “complete” manual flow rate calibration and got a spaghetti mess both times. I specified PETG filament in the external spool, the engineering plate, and it says the bed will heat to 70C, but the plate doesn’t heat up. Then the prints start to slide all over the place and the spaghetti starts. If I manually enter 70C in the Status page under the Device tab, it seems to work properly. But the calibration page leads you to believe that it is setting the bed temperature based on the filament and plate you specify - but it isn’t.
