Acknowledgements

This is a kit made from ideas from Fervi3D who posted his fantastic work on Thingiverse.

Also thanks to many 3D-print enthusiast who showed a big interest for us to offer this complete kit.


Introduction

This kit contains the necessary parts to convert to our freshly designed extruder that uses 3:1 gearing ratio for improved precision and resolution.

The Bondtech BMG 1.75 mm extruder is the simplest way to increase the performance and reliability of your Creality CR-10 V2 printer in a matter of minutes.

This new revolution in design utilizes the proven Bondtech Dual Drive Technology with precision CNC-manufactured parts. This gives the market’s best feeder performance and reliability.

The Upgrade allows you to prototype even faster and print with peace of mind.


Compatibility

The upgrade is compatible with the following machine:

Creality3D CR-10 V2


Recommendation

To get the best performance of this Creality CR-10 V2 Upgrade Kit, it is recommended to follow all the steps in this guide, but also the Stepper Current Adjustment on CR-10S guide.

    • After connecting a report is shown,

    • where the most important line refers the following: echo: M92...

    • At the end of that line you'll see E93.00. This is the value we must change.

  26. In the command prompt, insert the command M92 E415. This will set the E-Steps for the Extruder stepper to 415. Wait about 20 seconds.

    • This will save the setting to the Eeprom.

    • Finally send the M503 command.

    • This will output a status report.

    • Check in the status report if the values were saved and the setup is completed.

  27. Congratulations, you finished the Hardware and Software setup.

    • Congratulations, you finished the Hardware and Software setup.

    • Before updating the firmware we recommend you to adjust the stepper current. Follow this link to visit the guide: Stepper Current Adjustment on Creality 3D CR-10S.
