Dual parking carriage extruder Prusa i3 | E3D & 1730 FMH

thingiverse

This design is based on Jellebross' and 3D Proto's original work. http://www.thingiverse.com/thing:1446731http://3d-proto.de/ Dual parking carriage extruder. It uses one E3D Lite6 hotend and one 1730 Full metal hotend. The E3D Lite6 (V6 fits as well) for support and materials up to 240C, and the 1730 hotend for materials up to 400C. On each carriage, there is a 40mm high-airflow server fan to keep the hotend cool. Aswell as a part cooling fan. It uses two 12V 20N electromagnets to pick up and drop off the carriages. Two neodymium magnets on either side of the Z-slides hold them in place. The two electromagnets are mounted to the mid-carriage, as well as an inductive sensor to level the buildplate.
