Allow small negative brim separation gap value #12465

Open collord opened 6 months ago

collord commented 6 months ago

I am printing objects which at their base are full-width solid blocks, but at high detail (.1 mm) settings on my Creality Ender-3 S1. (Sorry, first printer, I didn't know better.) Using Prusa Slicer 2.7.1. A few mm up, past a certain amount of just infill, as things get interesting, the thermal stresses can be pretty extreme and corners like to peel up. Bed adhesion is critical and I have found brims necessary.

I have also found that (perhaps also due to undiagnosed feed rate issues? or incorrect Elephant Foot correction?) the brims aren't really attached to the objects consistently. See image:

I would like to address this problem, where necessary, by allowing a slight (limited to layer width?) overlap of the brim with the object.

UI would allow negative values for brim offset, up to layer width (?), but provide warning when negative.
