Extruder Upgrade Kit for QR Ultimaker 3
Bondtech QR Kit for Ultimaker 3 series.
This kit fits for: Ultimaker 3 and Ultimaker 3 Extended
Includes:
- 700 mm black polyester braided cable with quick-connectors, equipped with a JST-XH6 to JST-XH4 connector.
- Nema17 high precision geared steppermotor
This extruder upgrade kit for the Ultimaker 3 printers replaces the original feeders, it comes with it´s own Nema17 high precision geared stepper motor. This kit provides a high-performance material feeding system with the ability to print faster with improved quality. The adjustable thumbscrew allows you to fine-tune the force acting on the filament. 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 housing parts are professionally SLS printed in polyamide for maximum strength and precision.
The included mounts in FDM printed PETG installs at the top of the rear side of the printer.
E-steps needs to be updated to 492.45 step/mm and the feeding speed used when performing a “Material Change” from the LCD of the printer.
NOTE:
There is no firmware with updated e-steps available since the Ultimaker3 uses another type of firmware than the Ultimaker 2. For Ultimaker 3 the configuration needs to be updated directly on the printer, for more information please see the installation guide.
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.
For best performance also use PTFE tube 3.18/6.4 mm diameter as you can find below.
Installation:
Installs in about an one hour with standard tools available.
