with new white plastic main gear and integrated drive gear for lower run-out
Now including the new white plastic main gear and assembled with a new method to reduce run-out and improve 3D print´s surface quality.
The Bondtech DDX Direct Drive eXtruder for Creality 3D printers is an upgrade kit that replaces the original bowden with a direct drive setup. It is a high-performance Dual Drive extruder based on the BMG Bondtech Mini Geared.
Multiple Hotends Compatibility
This model was created to be compatible with the original hotend of each Creality model. Users may also upgrade the hotend to Copperhead or Mosquito.
The DDX v3 is much easier to install
With this integrated fan shroud and mount the DDX v3 is even easier to install.
Snap the fan to the shroud without using screws.
Adjust the height of the shroud with one front access screw.
Using a bed probe with DDX v3
The DDX was designed to allow space for the bed probe to be attached to the x-carriage. In models where there is no available space to attach a bed probe, like the BL Touch, to the X-carriage – CR-10 Max as example – a mount can be printed and attached to the right hand side of the DDX.
Bondtech DDX v3 Direct Drive eXtruder
This Direct Drive eXtruder from Bondtech is a high performance, high reliability 1,75mm Dual Drive extruder for Creality 3D printers, based on our very popular BMG. Bondtech’s unique Dual-Drive technology combined with either the factory hotend or for even better performance the industry leading hotends Copperhead™ or Mosquito™ from Slice Engineering, gives you a direct drive extruder with trouble free material feeding and enables the use of a wider range of materials. The housing parts are printed with PA12 (polyamide) for maximum strength and precision using industrial grade SLS technology.
Make your 3D printer even better
Bondtech DDX v3 Direct Drive eXtruder for Creality is designed to give the user more options – different materials; higher flow and/or wider nozzles; thinner layers – and achieve a higher print quality. The DDX v3 is based on the BMG Bondtech Mini Geared extruder featuring our unique Dual-Drive technology. The DDX v3 housing design provides an effective Hot-End cooling. With the 3:1 gearing ratio, high resolution prints with small nozzles or high flow prints with bigger nozzles can be achieved.

STEP BY STEP GUIDES
These Parts Are Required For The DDX To Function Properly
When assembling or disassembling your DDX extruder always keep the following elements and parts under watch. Ball bearings especially have the bad habit of sticking to the housing pockets, or falling off and getting lost.
Do not use your DDX without being sure you have ALL these parts.
Hinge and Secondary Drive Gear
The black plastic injected molded hinge holds the following parts:
- 1x 3x32mm shaft
- 1x 3x20mm shaft
- 2x needle bearings
- 1x Secondary drive gear
Main Shaft Assembly
The main shaft assembly holds the following parts:
- 1x Integrated main drive gear and shaft
- 1x black main double gear
- 2x 5x8x2.5mm ballbearing
To install the fan shroud on the DDX V3, and after levelling it, be sure to firmly tighten its screw so the fan shroud feels rock steady.
The guides below apply to the DDX V2 Direct Drive eXtruder for Creality.
You may use them to install the DDX V3 considering some specific and minor changes.
For detailed guidance on installing a DDX V3, please use the video under the “Video Guides” tab.
DDX For Creality Step By Step Guides
00. Changing Machine Settings
Guides For CR-10S Pro and similar
E-steps and Klipper settings
For Klipper usersrotation_distance = full_steps_per_rotation * microsteps / steps_per_mm
rotation_distance = 200 * 16 / 415
rotation_distance = 7.71
The above calculation assumes the following parameters:
- stepper motor is a 1.8 degrees motor hence 200 as full steps per rotation;
- If you are using a 0.9 degrees stepper motor, replace full_steps_per_rotation with 400;
- microsteps are set to 16;
- e-steps value recommended for the BMG / DDX is 415.
Although we recommend to use the rotation_distance instead of the gear_ratio, we inform the BMG / DDX gearing ratio is 50:17 .
Compatible with the following models:
- CR-10S Pro;
- CR-10S Pro v2;
- CR-10 Max*1;
*1 Using DDX v3 on CR-10 Max
On the Cr-10 Max the z-height will be limited to in between 430mm and 455mm, instead of the original 470.
This is due to the higher position of the push-fit on our extruder, that forces the bowden to bend at a lower level under the top bar. Use the Z(height) parameter at Machine Settings in the slicer to reflect this lower limit. Select the lower value and fine tune the max Z with testing.
