Installation manual Bondtech DDG Ultimaker V2.0
Software Configuration
Ultimaker 2+ and Ultimaker 2 Ex
The Ultimaker’s firmware needs to be changed since the new feeder uses another E-
step value and also the speed for loading/unloading material needs to be lowered in
order not to stall the stepper motor. The reason for this is that the Bondtech Dual
Drive system has a different drive gear diameter and needs a bit more torque while
loading due to gripping the filament on both sides. The additional grip allows to push
the material with higher force and reliability.
Below you will find links to the latest firmware that is based on original Ultimaker 2.1
firmware.
The following is changed when compared to the original:
E-step is now 311 and Loading speed is 50 mm/sec

Ultimaker 2 Ex Firmware:
Once you have downloaded the firmware use Cura to install the new custom
firmware on your printer.
After the firmware has been installed you need to perfo
rm a “Factory reset” on the
printer to ensure that the printer uses the new values in the firmware.
After the restore to factory settings is complete you will have to level your build plate
and load material (the same procedure as when the printer was new).
