Is there a way to stop the slicer adding bridging on an overhang?
My part is printing in PLA and has a thin horizontal slot. Printing support in place for the slot is very hard to remove from the slot. So I came up with the idea of pre-printing a PETG piece that fits in the slot and provides support. So just before the overhang is printed the job pauses, I insert the pre-printed support then resume. After printing, the PETG piece is easily removed in one piece.
But the slicer insists that the “overhang” is printed as bridging as there is no way I can tell it it is fully supported and can print a normal shell. The surface finish of the top of the slot would be better if it printed a normal shell layer.
