Adjusting retraction with Skeinforge


Our best Skeinforge plugin for eliminating ooze and stringing is the retraction setting in Dimension. This plugin allows for adjustments that control how much filament is fed to the hot end.

In this recipe, we're going to make adjustments with retraction speeds and distances to better refine our printing results.

Getting ready

We'll use the SketchUp model for this recipe as well. An extruder using a Bowden cable system would be great for testing these parameters. Bowden cables have a tendency to ooze and string a filament.

How to do it...

We will proceed as follows:

  1. In Skeinforge, open the Dimension plugin. Go to Extruder Retraction Speed (mm/s) and change the default value 12.0 to 32.0.

  2. Print the surface test model.

  3. Go back and change Extruder Retraction Speed (mm/s) to 85.0.

  4. Print the surface test model.

  5. Keep Extruder Retraction Speed (mm/s) at 85.0 and scroll down to Retraction Distance (millimeters) to change the default value from 0.0 to 1.2.

  6. Print the surface...
