Firstly, it disagrees with its product page, which clearly (STILL!) specifies that its hotend temperature limit is 280: https://github.com/prusa3d/Prusa-Firmware-Buddy/commit/9e91e876091aab34cc6b9ffca65e798c1e52c713
Secondly, it disagrees with Prusa's own documentation, such as for hot tightening, which clearly states that you need to heat to 280C: https://help.prusa3d.com/article/changing-replacing-the-nozzle-mini_134235
Lastly, and most hilariously, this disagrees with _the rest of the firmware_. The Mini has a ... quickly design that you can't just load filament. (cont)
