Creality Official E·Fit Extruder Dual Drive Feeder with High Torque Stepper 3:1 Gear Ratio Support Bowden&Direct Extrusion Upgrade Kit for Ender 3/Ender 3 V2/Ender 3 Pro/CR 10 3D Printers

The Creality Official E·Fit Extruder is a must have for your Ender 3. It utilizes a 3:1 gear ratio and it is equipped with a high torque stepper motor. One of the best aspects of it is that it supports both Bowden and direct extrusion setups. It has a quick release which makes disassembly easier and allows for quicker swaps of the hot end.With the 3:1 gear ration it will grip the filament tighter so there will be less of a chance of it jamming. If you have an Ender 3 or CR-10` series, then you should get one of the Creality Official E·Fit Extruders. I highly recommend it!

Fonctionne bien sur ma cr-10 v2

This is a wonderful upgrade for the Ender 3.The video is a useful addition to the instructions that come with the kit, however I found the bolt on the lower V wheel was shown to be fitted the same way as the two higher V wheels, but the end of the bolt kept striking the gantry preventing contact with the X stop. Once fitted the other way round it cleared the gantry and all was fine.I have found the curved part fitted to the bottom of one of the fans is very close to the bed and can sometimes catch the print knocking it off. I will be removing it once the current print finishes.I have an EZ ABL probe and the new back plate holes were only marginally different from the original back plate and with a bit of filing the probe mount fitted a treat. The new position of the probe relative to the nozzle meant a delve back into Marlin coding and flashing the firmware, something I had not done for many years.Changing filament is a breeze , no more multiple menu clicks and button presses - just heat the nozzle to 200, lift the quick release lever and it comes out. Feed the new filament in and with a bit of pressure you can purge the nozzle and are ready to go.Overall I don't know why I waited so long for this upgrade.

Avant le montage, faire un test pour calculer le pas/mm. C'est plus simple qu'une fois monté. La doc donne 405 pas/mm, j'ai environ 426pas/mm pour un test de 30cm. Sur la Ender 3 avec son Hotend d'origine, la sortie des fils du hotend doit être du coté de la plaque supportant le ventilateur de buse. Donc le Hotend est monté/positionné comme d'origine. Les fils passent alors derrière le radiateur, entre radiateur et plaque des roues, pour sortir vers la gauche (en passant derrière le CR-Touch si installé). Le ventilateur de radiateur doit être positionné avec les fils sortant en bas à gauche. Si CR-Touch, il faut remesurer les distances XY entre la buse le capteur. X-24 Y-4 de mémoire.

Not able to be used on CR10 Smart or CR6SE printers due to the load cell in the hot end setup. Had high hopes of converting my machines to direct drive, but these are NOT universal.
