Filament grinding can occur as the result of several other issues. Read on to find out what causes it and how you can fix it!<\/p>\n<\/div>\n<\/div>\n

What Is It?<\/h3>\n<\/div>\n

If you\u2019ve been lucky enough never to experience the infuriating problem of filament grinding, it\u2019s when the\u00a0extruder<\/a>\u00a0chews away at your material. Mostly it happens when your\u00a0filament gets stuck<\/a>\u00a0but the extruder gear doesn\u2019t stop moving. Instead, it keeps going and strips the filament with its toothed gear.<\/p>\n

When this happens, the filament ends up becoming so concave that the extruder gear can\u2019t reach it anymore. You can identify filament grinding by seeing your filament chipped or stripped in one area around the extruder.<\/p>\n

This problem is very annoying and can be challenging to fix, but don\u2019t worry, we have some solutions. To identify the correct solution, though, you\u2019ll need to first locate the cause, so that\u2019s what we\u2019ll look at in the following section.<\/p>\n<\/div>\n

Why Does It Happen?<\/h3>\n<\/div>\n

Before we get into the solutions, pinpointing this problem\u2019s causes will help you both fix it and avoid it in the future.<\/p>\n

The direct cause of filament grinding comes from the extruder attempting to push the filament. Failing to do so, the extruder leaves a divet in the filament, as seen in the image above.<\/p>\n

That\u2019s not the only cause of this problem, though; a few different factors contribute to filament grinding. We\u2019ve listed most of the known causes of filament grinding below:<\/p>\n
