Additional system information

No response

Printer

Qidi Plus 4

How to reproduce

Adjust slicer temps to be wildly different, 290c first layer - 30c other layers
Slice

Actual results

Slicer follows through with slicing, ignoring the default temp range set in filament settings.

Expected results

Slicer realizes temp is out of spec of the set range and throws and error. Limit acceptable temps to the range set in the filament settings tab. Also should prob have some sort of check to make sure there aren't massive changes in layer temps. 290c to 30c should be easy to tell isn't right.

Also how is this not already implemented? Its a basic safety feature.

should prob have 2 checks, temp within specified range, and temp within % of range.
