Good morning all

I have a Rasie3D Pro2 printer at work and mostly its been ok lately I have been experiencing a characteristic that I can stop happening every time.

The top layer is a good finish and parallel with no gaps but seems to be 0.1mm lower than the outer perimeter shells and any internal shells with a smooth transition.

Please see the attached jpeg that shows an exaggerated picture of the part when looking from the end if it was cut in half

Ive been using the various in built templates in the printer and it happens if its PLA or ABS

Any help or suggested solutions or reasons would be appreciated

regards

Dave
