BCN3D 3D Printer Shims Set for use with BCN3D Epsilon 3D-Printer, BCN3D Sigma R19 3D-Printer, BCN3D Sigmax R19

Shims are elements that mechanically correct the Z offset when printing in Mirror or Duplication mode. These printing modes are available for all Sigmax versions and for the Sigma R19. Those Sigma users who have previous versions must update their firmware to 2.0.0 or higher to have them available. Visit our Support page to learn how to do it. In these modes both toolheads work simultaneously, so it is key important to make sure both nozzle tips are exactly at the same height. Due to manufacturing and assembly tolerances the Z offset between tips can be up to 0.5mm. BCN3D printers automatically correct the offsets when printing in Mirror/Duplication Modes. However, this correction distorts the first layer of the model by repeating it as many time as needed.
