This extruder upgrade kit for the Ultimaker printers replaces the original feeder, it comes with it´s own Nema17 high precision geared steppermotor.

It allows for a more reliable printing with all sorts of filaments, both stiff and flexibles and the DualDrive system ensures that the extruder never looses grip of the filament so grinding, slipping is a thing of the past.

The high resolution makes printing with small nozzles <0.30 mm a simple task for those high-res prints.

The included mount in SLS printed nylon installs in the holes used for the factory extruder and has an included vibration isolation foam to be placed between the rear side of the printer and the mount.

Also the gearbox that the mount clamps around is fitted with a vibration isolation foam to reduce the vibration from the stepper-motor to transfer to the printer frame to reduce sound during operation.

Installs in about an half hour with standard tools available.

E-steps needs to be updated to 492.45 and the feeding speed used when performing a “Material Change” from the LCD of the printer.

Firmware with adjusted E-step and feeding speed is available for Ultimaker2, Ultimaker2 Extended, Ultimaker 2+, Ultimaker 2+ Extended.

You can also send a M-code to the printer directly to set the e-steps (more info here) under the section E-steps, but remember that using the “Material Change” from the LCD on the printer will not work as it will stall the motor.

The reason for why the stepper motor stalls is that our motor uses a planetary gear reducer, this means that the motor will have to turn faster to feed at the same speed as the original feeder.

Full installation guide available at the tab installation guide

For best performance also use PTFE tube 3.18/6.4 mm diameter as you can find below.

  1. GMAC

    Everything you need to completely replace the stock feeder in an Ultimaker 2. Very little assembly required, the extruder itself comes 99% assembled & ready to go. All you have to do is remove the old extruder, install the new mount and then bolt the new extruder to the mount you have just fitted using the clip provided. Most of the assembly is intuitive for anyone familiar with their machine, but Bondtech do provide a complete set of illustrated instructions online.

    Build quality is top-notch. Everything lines up as it should with the UM2 housing. The main unit feels sturdy & well constructed.

    Adjustments need to be made to the machine firmware because of the new gearing, but this is unavoidable. However, Bondtech provide firmware files that are ready to go as well as the specific esteps/current settings should you prefer to compile yourself. We used the settings provided by Bondtech on TinkerGnome firmware with no problems at all.

    Effect on print output is immediate. No more grinding & we can now also print flex which the stock feeder can never accomplish. The extruder is constructed in such a way that filament can be inserted or removed by hand where necessary using a simple thumbscrew to release the grip.

    Overall, worth every penny.
