extra perimeters with large nozzle and custom extrusion width #1097

Closed Jerrill closed 8 years ago

Jerrill commented 11 years ago

I'm slicing for a 0.80 mm nozzle. If I have a custom extrusion width of 1.0 mm a 2.1 mm ring has 2 perimeters. In the upper cylinder portion of the model there's a small gap but it works. If I change to something like 1.2 mm or 1.3 mm then I end up with a third perimeter and the the layer is way over extruded when it prints.

I've posted all the relevant files to reproduce the issue here.

Not sure I get it, are you sure it's overextruding because of a toolpath issue and not just for miscalibration of flow?

Aren't those three loops spaced by the extrusion width you configured?

That STL is actually being detected as 2 separate meshes that are interspersed, not as a single piece.

I'm not seeing a third perimeter with bad.ini though. Closing.

Not seeing the issue with current version of slic3r, and the model has some oddities with it (it's actually two meshes, not one).
