Introduction

This guide shows the installation process of our BMG upgrade kit for Wanhao D6.


Bondtech Firmware for Wanhao D6

The new extruder and motor have a different geometry compared to the original one so in order to avoid the print head crashing into the rear panel you should download and flash our custom made firmware. You can download the firmware here:

The following is changed from the default firmware.

  • Set E-step to 415: #define DEFAULT_AXIS_STEPS_PER_UNIT{80,80,400,415}
  • Set Max Y axis to 183mm: #define Y_MAX_POS 183
  • Reverse direction of extruder motor: #define INVERT_E0_DIR true


Bondtech Firmware for Wanhao D6 Plus / D6 MK2

For the Plus (or MK2) model you can download the firmware here


Important

On some printers it is necessary to add an O-ring to the plastic parts that activates the end stop in y-axis as the extruder otherwise can hit the frame when doing a homing to y zero. You can find the Guide at the Parts section below.


After installing the new firmware

perform a "Restore to factory defaults" from the LCD panel to make sure the new values are used.

After the Factory Reset, don’t forget to level your build plate.

  1. THIS STEP IS NOT REQUIRED IF YOU ARE PLANNING TO UPDATE YOUR FIRMWARE WITH  OUR CUSTOM VERSION. Because we are using a geared extruder we need to change the position of the motor cable wires, otherwise the motor will rotate the wrong way. Use a sharp tool to press down the small locktab in the crimping contact to remove the 2 left most wires.
