I seem to have problems with my Flashforge Adventurer.

I have a model, small 5 cm human figure, and it always prints a crack at the neck.
The model is without errors.

The same happens with a robot torso, just one crack on one side each print.

It looks like there's something wrong with the export or the reading of the file from USB.

I tried slicing the model multiple times, different hotness nozzle, 200 micron, 100 micron etc. etc. all the same result.

Can anyone help?

I tried contacting Flashforge, all done already.
