Adjusting retraction with Slic3r

Slic3r also has retraction settings that can be adjusted for eliminating ooze. In this recipe, we're going to make adjustments with retraction speeds and distances to better refine our printing results.

Getting ready

You'll need the SketchUp model and, preferably, a PLA filament for this recipe. It would also be best if you have a Bowden cable system for printing the tests.

How to do it...

We will proceed as follows:

1. Print the test model using the default settings of the PLA filament.

2. In Slic3r, under Printer Settings, go to Speed and change the default value from 30 to 45.

3. Print the surface test model.

4. Go back and change the Speed value to 80.

5. Print the surface test model.

6. Keep the Speed value at 80 and scroll up to Length to change the default value from 1 to 2.

7. Print the surface test model.

8. Go back and change Length to 3.2.

9. Print the surface test model.

How it works...

Overall, the default settings for Slic3r work well. Remember that every machine is going to work with...
