This extruder upgrade kit for the BCN3D Sigma printer replaces the original extruder and comes with its own high-precision Nema17 stepper motor.
It allows for more reliable printing with all types of filament, both rigid and flexible, and the Dual-Drive system ensures that the extruder never loses its grip on the filament.
Printing with small 0.30 mm nozzles allows for high resolution. The included PETG substrates printed with an FDM printer are installed in the original position.
It installs in about one hour with standard tools available.
Electronic steps must be upgraded to 511.
Check the installation guide for more information on firmware.
For best performance, also use 3/6 mm diameter PTFE tubing.
