Retraction Tuning with PrusaSlicer

thingiverse

<h1>General Information</h1> The included .3mf file can be opened with the latest PrusaSlicer release and modified to create retraction tuning G-code that quickly fine-tunes retraction settings. The raw STL file is also included for use with other slicing software. This calibration procedure is designed for use with an 80-90% tuned PrusaSlicer profile, where extrusion multiplier, extrusion temperature, linear advance K factor, and speeds are already well-calibrated. This test helps round out the profile by fine-tuning retraction distance and speed. You can also use this test to adjust fan settings, including auto-cooling min layer times. <h1>Instructions</h1> - 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 > Extruders: (See pictures for reference). - Each extruder is accessible for custom retraction setting configuration via 'Printer Settings' tab > Extruder 1, Extruder 2, Extruder 3, etc. (See pictures for reference). - On the 'Plater' tab, each retraction tower STL is configured to print with a different extruder in sequential order around the build plate (See pictures for reference). Take time to familiarize yourself with how the project is configured with various extruders, then load your own custom profile with appropriately tuned settings for your machine. Note that the .3mf file shared here is set up for a 0.8mm nozzle, and reconfigure the extruders accordingly. The retraction tower STLs will automatically reassigned to whatever extruder they had before config change, allowing you to adjust retraction settings as needed. **Note:** Pay attention to what is entered under [ 'Printer Settings' tab > Extruder "X" > Retraction when tool is disabled (advanced setting for multi-extruder setups) ]. This setting defaults to 4mm and will force the extruder to retract by 4mm between each part as it changes from one extruder to another. Set this to zero! (See pictures for reference).
