How to wipe properly (fixing external loop defects from wiping)

[Trydnt]

Issue:

The current wipe on retraction setting can lead to nasty imperfections in the external wall as it wipes back onto the most recent loop. This can be sanded down on hard filament but when using flexible filaments this isn’t an option and these flaws can sink an otherwise great print.

Proposal:

FaceSaver (cool name to boot)
When completing an external wall loop, wipe on the innermost wall instead of on external walls.

Easy to implement:

This wipe movement will already have been performed so the G code is already written for it, it just needs to move directly to that spot and perform the wipe again after the external wall loop finishes and never wipe on an external wall loop.

Bonus: (but harder to implement)
Wipe in opposite direction so as to avoid getting debris on the nozzle
