Creality Ender 3 Pro Extruder Replacement

はじめに

This guide's intention is to solve problems like your filament grinding in your Creality Ender 3 Pro. This is often caused by the extruder arm applying too much pressure (or too little) to the filament. To complete this guide, you should have a replacement extruder ready for your extruder mechanism, which you can purchase online.

All the tools you need are a 2.5 mm hex key, a 8 mm wrench, and around 10-15 minutes of your time!
