This video teaches what extruder retraction is, and how to prevent print artifacts without causing an extruder jam.
- [Instructor] When you're using a 3D printer,…sometimes you want to stop what it's doing…within a layer to create open spaces,…or so called islands in the print.…Pulling back the filament is called retraction.…If you retract too little, you'll get stringing,…which is what we see in the pictures here.…If you retract too much, you may have filament jams.…We'll talk about what the retraction settings mean.…If you're not having stringing issues,…it's best to leave retraction settings…at your manufacturer's original settings.…In this video, many of this issues we'll talk about…will not be visible on the simulated print…and the slicing software.…
And one of the challenges is,…is that the reality of the print might be a little…different than it is on the screen.…So here in Matter Control we have a print…that's very vulnerable to having retraction problems.…It's two tall towers next to each other,…with little spacing.…And so what we're going to do is go to Settings & Controls,…and open the Retraction settings,…which are under Filament and Retraction.…
