Retraction Tuning with PrusaSlicer

General Information
The included .3mf file can be opened with the latest PrusaSlicer release (https://github.com/prusa3d/PrusaSlicer/releases) and modified for your hardware configuration in order to create retraction tuning gcode that is quick and effective at finely tuning retraction settings. I've also included the raw STL file for use with other slicing software.

This calibration procedure is intended for use with an 80-90% tuned PrusaSlicer profile, wherein the extrusion multiplier, extrusion temperature, linear advance k factor and speeds are pretty well calibrated already. This test is to help round out the profile with proper retraction distance and speed. You can also use this test to play with fan settings, including tuning auto-cooling min layer times.

Instructions

- Click on [ File > Open Project... ] and find/open the "Retraction_tuning.3mf" file
- The slicing configuration includes 9 extruders [ set via 'Printer Settings' tab > General > Capabilities > Extru
