The two parameters for this setting are Distance and Speed. Retraction causes your printer to pull some filament back when moving the print head in between parts of your print. Most every slicer has this ability, and thankfully this is more than likely your issue if stringing is an issue. If stringing is prominent on the longer distances then I would look into the troubleshooting steps. Small strings often referred to as hairs are very common at small distances and are very easy to clean up after the print has finished. stl tests stringing from 0mm to 15mm by default. Too high of a Temperature would cause a host of other issues in your prints so if you are mainly just experiencing stringing then Retraction is probably your issue.

The two major factors affecting stringing are Retraction and Temperature. The inventor file is available on my website This model only uses one parameter, the longest distance you want stringing to be tested at and it automagically does the rest for you. ipt file if you have Inventor and would like to make modifications to this. They are set up so that they test every length from 0mm to 15mm by default. This model is fully parameterized if you have Inventor. If you are unfortunate enough to have extreme stringing, then this guide and the included test print should get you up and running in no time. Luckily cleanup for Stringing is generally pretty simple as long as the stringing isn't extreme. Stringing, also often referred to as Oozing, is when a print has small hairs or in extreme cases thick lines of the filament in between the outside perimeter of two print locations. This is the beginning of a larger suite of test prints I am developing that can be used to calibrate your 3D printer cheaply, and quickly. Go to My full list of 3D Printing Troubleshooting Guides
