Installing shims
The BCN3D Sigma Series features four printing modes: Single, Dual, Mirror and Duplication. During Mirror and
Duplication both toolheads work simultaneously.
To do it successfully it is key important to make sure both nozzle tips are exactly at the same height. However, due
to manufacturing and assembly tolerances the offset between tips can be up to 0.5mm.
The BCN3D Sigma Series automatically corrects the offsets when printing in Duplication/Mirror modes by printing
a raft in the toolhead that is higher. However, this correction may distort the first layer since it’s not printed directly
on the glass surface.
During the Printer Calibration process or before printing a job with Duplication or Mirror mode, the BCN3D Sigma
may suggest you to install shims to correct the Z offset between nozzle tips. To correct this offset, there are diffe-
