Greetings,
It would be great if we could tweak a few other settings for the very first layer above the new and improved v4.0 raft. Specifically, Outline Overlap and Extrusion Multiplier. Because this layer is raised above the raft for easier separation, the extrusion isn't pressed flat and spread out as it is on all other normal layers. As a result, the fill does not get adequate overlap with the perimeters and itself (as shown). For this layer, I suspect that the outline overlap needs to be boosted to 50%+.
Also, the extrusion width itself is not adequate on the first interface layer. Increasing the extrusion multiplier for this layer might work and could be an easy fix. But it might just extrude too much material and make the part bond to the raft too much. A more complex fix would be to add more densely packed passes that accommodate for the thinner extrusion width. At the code level, this would be equivalent to overlapping passes to accommodate for the thinner extrusion width. Or rather, look at it like the printer has a narrower nozzle opening and just needs to make more passes to properly fill the the interface layer without creating gaps.
Thanks for any consideration on this,
Sean
