Example: I had one today that looked like it was on the bed, but and I should have been suspicious when the brim didn't appear on the slice. Spaghetti print. This happens a lot to me because .stl files often have a weird orientation and you need to flip them. The slicer looks like it is snapping them to the bed but often they are not actually sitting on the bed. I need to get in the habit of using the sit flat function, flip over the bed and select the bottom of the object but I am an impatient person...
