This extruder upgrade kit for the BCN3D Sigma printer replaces the original feeders, 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 mounts in FDM printed PETG installs at the original position.
Installs in about an one hour with standard tools available.
E-steps needs to be updated to 511 .
Check the installation guide for more information about the about the firmware.
Full installation guide available at the tab installation guide
