A lot can go wrong when you're printing a 3D object, with the inconvenient "stringing" being one of the most common.

When the 3D printer gives up, don’t wait for the experts. Here are solutions to the most common problems: layers failing to attach, stringing, and overheating.

The fix was also easy, and completely mechanical — just a couple of parts to replace. The video below shows the whole diagnosis process, as well as the before and after comparisons.

In the video after the break [dizekat] gives us a throwback to those times with the Marionette 3D printer, completely forgoing linear rails in favor of strings.

Well, that's exactly why I decided to put together this guide. If your 3D printer is making weird noises all of a sudden, here's what could be causing it, and how you can fix the issue.
