● MK8 extruder

● Resume Print - Our upgraded control board offers state of the art, "Resume Print" technology. Should your printer suffer unexpected power outages, it will resume from the last recorded extruder position.

 ● High-precisions ball bearing wheels made from Delrin/POM engineering thermoplastic deliver high stiffness, low friction, and excellent dimensional stability helping to reduce noise levels greatly.
 
 ● Redesigned with a much more sturdy, 40x40 aluminum extrusion for the Yaxis base. This provides unprecedented stability for the printing surface, resulting in upgraded print quality.
 
● The magnetic bed:
Our all new state of the art“C-MAG”magnetic sticker, is completely removable, and flexible.
