Offizielles Creality Upgrade Aluminiumteile MK8 Extruderlegierung Block Bowden Extruder 1,75 mm Filament für Ender3 / Pro Ender5
I bought this set to replace the one on my ender 5 plus. Though I'm really happy with the quality of the product, the main screw for the lever is too short to fit with the now 1mm thicker assembly. A workaround is to use the arm-"bearing" of the old assembly. Additionally, a 1mm plate needs to be mounted between the mounting bracket and the filament sensor, otherwise you will get feeding problems.
Maybe there is a better kit for the Ender 5 plus by now.
Very simple to replace, improved print quality immensely, no issue with under extrusion. With the M10 pneumatic coupling instead of the M6 means that you are feeding directly into the bowden tube making feeding much easier. Highly recommend this upgrade.
