This object from whpthomas’s collection exercises the deprime operation in Sailfish, but it seemed like it’d be useful to verify the Marlin settings in the M2:
From the other side:
Yes, that was rather anticlimactic. No ooze, no stringing, no surface finish blemishes, just the finished object on the build platform’s glass sheet.
I like that!
The slight bumps on the sharp corner edges seem to be due to the crazy-high perimeter and infill speeds I’ve been playing with, although (I think) those are also where layer changes occurred. The first layer height came out a bit short, so there’s a small flange around the object’s bottom edge; I was figuring out how to get a precise level across the entire surface and stabilize the Z-min switch operation.
The slic3r configuration:

No source code, as it’s directly from the STL on Thingiverse; I have no idea which modeling program he used.
