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.

Easy To Setup

For ease of setup the kit is attached to the carriage with only 2 screws.

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.

E-steps and Klipper settings

For Klipper users

rotation_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 .

Compatibility Table

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.
