Dual extrusion - alignment errors

I ran up the dual extrusion wizard to generate the files for my Flashforge Dreamer to produce a black dice with white spots.

In the Y axis and Z axis the white / black surfaces correctly aligned but in X there was an obvious offset (about 0.5mm).

Has anyone else experienced this and suggestions to correct it would be appreciated.

I think you can edit the toolhead offset on the LCD panel. If not, just use the following command at the top of your starting script:
M218 T1 X22.5 Y0 (where the X-value is the offset between the toolhead that you would be adjusting)

Yeah... sounds like the dual extruders need a bit of calibration... Find a calibration print or follow the manufacturers instructions for calibrating.
