OS Version

Windows 11

Additional system information

No response

Printer

Voron 2.4

How to reproduce

Filament settings
Change min fan speed f.e. to 20
Change max fan speed f.e. to 8

No notification that anything is wrong

Actual results

I recently, by mistake found an issue (not causing much problems), that You can set min fan speed higher than max fan speed. No info after slicing says that something might be wrong. Just when started printing I heard that printer is not working as it should be.

Expected results

Add safeguard for changing min/max fan speed similar to min/max printing temp and min/max filament temp, so You canot slice or save profile when fan speeds are inverted.
