Right extruder board for Creator 3
Note, There currently exist 2 versions. Version 0.6 and version 0.9.
Flashforge has August 2019 switched to a newer extruder sensor with a 3-pin connector, instead of a 2-pin.
For this reason the extruder board has been updated to include a connector that fits.
If your creator 3 is before August 2019, version 0.6 is the board that fits.
If you are not sure what version have, the number is written on the extruder board itself.
