Heating and Homing: Bed Temperature increased to 70°C instead 50°C from gcode file

[MarkusP]

Did you test the latest extui code or prerelease?

No, I cannot complete

Bug Description

Created an gcode file for printing TPU. Used latest Cura Slicer (4.9.1) and Generic TPU 95A with 0,4mm Noozle as profile. Noozle temperature (printing and initial) is 230°C. Heatbed temperature (printing and initial) is 50°C.

After exporting the gcode file and selecting it from the sdcard to print it, the following happens:

• heatbed will be heated up to 50°C
• noozle will then be heated up to 230°C
• right after that the "heating up and homing in progress" screen appears and
• right that moment the heatbed will be heated up again, now to 70°C

Have you looked at your start gcode in cura? You may want to use Sabazzz's start code at the following link:
