Pressure Advance Overrides

The Pressure Advance value on a material variant now reaches the printer on both slicing engines. Set it once (Materials, then the variant, then Pressure Advance) and every job that prints in that filament slices with it, whichever engine the part uses. Leave it empty and the filament profile's own value applies, exactly as before.

This is a fix as much as a feature, and it is worth a look if you set the field in the past. Both slicers read filament settings from a config format that only accepts text, and we were writing the number as a number, so the value was dropped on the way in. The slice still succeeded and the plate still printed, just with no pressure advance command in the G-code at all. Anyone who set a value and could not see it in their prints now has it applied on the next slice, so check the number on your variants before a long run.

On Bambu Lab printers sliced with Bambu Studio, the value goes into the filament start G-code, which is the one route that works there: Bambu Studio emits no pressure advance command of its own for those machines, and the printer otherwise uses whatever the AMS calibrated. Your value now wins. Every other combination gets the command its firmware expects, so Klipper machines get SET_PRESSURE_ADVANCE and Marlin machines get M900.

Values stay in the 0 to 2 range the field has always shown and are applied to three decimal places. The in-app help text and the materials documentation have been updated to match, since both still described the setting as OrcaSlicer only.
