Defining nozzle offsets
On Artifex 2 Duo, the left extruder is defined as Extruder 1, and the right one Extruder 2.
Ideally, the two extruders are perfectly aligned on the Y-axis direction, and positioned 42mm
away from each other along the X-axis direction. However, the clearance allowance between
mechanical components and other minor misalignments may change the offsets between
these two nozzles. The default nozzle offsets are defined in the electronics firmware, where
the offsets of Extruder 1 are always
X
= 0
mm
and
Y
= 0
mm
, and the offsets of Extruder
2 are
X
= 42
mm
and
Y
= 0
mm
.

First, reset the nozzle offsets to the default values using the M218 command (Fig-
ure 6.8).
