prusaslicer 2.8.0 ironing bug #13103

Open lemonhole opened 1 month ago

lemonhole commented 1 month ago

Description of the bug

Since version 2.8.0, ironing is applied at an angle to the top infill, that looks bad.

Before version 2.8.0, ironing was parallel to the top infill.

Is this a feature? Maybe should add settings like "ironing angle"?

3) enable ironing

reproduced this bug in 2.7.1 i almost sure ironing lines were parallel to top infill last time i was using it. maybe some of the settings cause this behavior

Ironing always was along the X axis. Research shows that ironing works best when it is at 45 degree angle to the infill pattern, so the default 45 degree angle of infill, so everything is built the way it's supposed to be.
