Printer

Prusa XL 5T and Prusa XL

How to reproduce

1. Select Prusa XL 5T printer with 0.4mm nozzle, PLA filament and some fast print profile for PRUSA XL 5T.
2. See that the print settings for slowing down on overhangs are incorrect
3. (Optional) Right click on the build plate and select "Add handy models" => "Slice "Autodesk FDM Test". Slice it and select speed view. See that the extreme overhangs are fast, while easy overhangs are very slow

Actual results

Incorrect slicing settings for slowing down on overhangs

This is how it looks sliced

So basically, it is fast on extreme overhangs, but slow on easy overhangs, which is wrong

Expected results

Speed should be fast on easy overhangs, but slow on extreme overhangs, just like for any other printers. Prusa slicer has it correct, but not orca slicer.
