PETG with PLA support settings, strength optimised

This is a test print with the settings I identified to both improve quality and reduce purged filament as far as I could.

Settings are for printing in PETG with a PLA interface layer for supports.

Settings for both OrcaSlicer and BambuSlicer are included (see files).

The following settings have been changed:

• Retract before cutting is active to use more of the flush volume to actually flush
• flushing is minimal when changing from PETG to PLA, while it is maxed out when going back from PLA to PETG to allow for good layer adhesion of the actual part
• there is a wipe tower to keep residue minimal; increased wipe tower flushing volume to 250 mm³
• Z distance and line spacing are 0 to allow for no sag of the supported area

All of these settings combined lead to relatively low filament waste (as far as possible…) while still making the test part strong enough to not allow me to break it by hand, which is really really easy if you have any PLA residue left in the nozzle when continuing to print your part.
