Hi All, I have been trying to print a moving part, a cylinder enclosed within a larger structure, there is a 0.012 in gap all around the cylinder and I am unable to get the gap to appear in the print. Here is a picture of the part in cura: I am printing on a UM3 in ABS. Can someone help me verify if this should be possible and if my settings are correct? Thanks, Dan
