Misaligned Nozzles - MakerBot Replicator 2X User Manual

MISALIGNED NOZZLES

MakerBot executes an alignment script on every MakerBot Replicator 2X before
shipping. However, if plastic coming from the two extruders does not appear to be
aligned correctly during dual extrusion prints, you can run the alignment script again
at home.
1. Make sure filament is loaded into both extruders.
2. To start the nozzle alignment script, go to the LCD menu and navigate to Utilities >
Calibrate Nozzles.
3. The MakerBot Replicator 2X will heat the build plate and extruders and then print a
test print for aligning the nozzles.
First, one extruder prints a series of straight lines parallel to the front of the build platform,
starting at the front left corner of the platform and extending to the back left corner of the
platform. The other extruder then prints a second series of lines, perpendicular to the front
of the build platform and starting at the center of the platform and extending to the left.
The second extruder then prints a line alongside each line printed by the first extruder.
4. When the test print has completed, you will see two sets of lines. Each set includes
two sets of 13 parallel lines, one set printed by each extruder.
After the test print is completed, the LCD menu will provide new instructions and prompt
you for input.
