Updated Version

Now this upgrade is supplied with the newest version of the Bondtech Mini Geared (BMG) extruder, featuring brass motor gear, black POM main gear, and threaded push-fit.

Increase Your Printer’s Value

The BMG Bowden Upgrade Kit for the CR-10S Pro uses Bondtech Dual Drive Gears to give extra push force and resolution plus a tighter fit between gears and housing to avoid filament jamming.

This kit is adapted for the Creality CR-10S PRO 3D-printer.

Built for the Creality3D CR-10S Pro

This extruder upgrade kit is for the Creality CR-10S PRO and will replace the original feeder. This kit contains no motor, the original motor is used.

Bondtech`s Dual Drive Performance

This kit provides a high-performance material feeding system with the ability to print faster with improved quality. The adjustable thumbscrew allows you to fine-tune the force acting on the filament. It allows for a more reliable printing with all sorts of filaments, both stiff and flexible and the DualDrive system ensures that the extruder never loses grip of the filament so grinding, slipping is a thing of the past.

Lower Current Recommended

Due to the gearing ratio, the stepper motor can push filament with such force the Bowden tube can be extruded in case there is a clog. To avoid such damage, we recommend lowering the stepper motor Current to near half the original current. Check the Step By Step Guide that teaches users how to do it.

Bowden Solution

The Bowden tube is securely held in place by the 4mm industry standard integrated push-fit connector.

Reducing Filament Jams

There is now a near to 0,1mm gap between the Bondtech gears and SLS 3D printed housing that avoids filament to jam in there. An additional short PTFE Tube is added between the Extruder and the Filament Sensor to allow for easier filament loading and unloading.

SLS Printed Housing

The housing parts are professionally SLS 3D printed with polyamide for maximum strength and precision. Due to the slightly higher geometry of the extruder, the total print height will be 385 mm.

Firmware Update

The Creality3D Firmware needs to be updated in order to use this Upgrade Kit. The E-steps need to be updated to 415 and the total print height is set to 385 mm.
