Behavior

When sliced the 0.4mm version of the calibration cube https://www.prusaprinters.org/prints/69934-helix-test-cube-filament-sample-xyz-calibration has two identical runs of bridging but on different axes, above the 'X' and 'Y letters. On the X side the bridging is perfect, on the Y side it does two lengthwise runs either side then tries to bridge sideways between them which fails with lots of loops hanging underneath. The bridging should run between the corner pillars in both directions.

Possibly related to #7103 - if that one worked I may not have noticed the loops with the bridging running this way, although running lengthways between solid pillars would still be a better solution overall.

Hi there - I just came across this problem when slicing this model. Resulted in some of the bridges running in the correct orientation (across the gap) and some perpendicular to it. As a result, the bridges sag for the first layer. Here's the slicing result from win 2.4.0:

The same file, sliced in the current SuperSlicer release:

Thanks

Thanks, your second image is exactly the way I think it should be done.

Nothing new? The first report of this issue is from october 2021. So, a bump for this.

It looks like it is still existing in 2.6.0-alpha5

Can confirm with hagre with the same file yoyo24 used in 2021.

Sadly still exists in 2.7.1.
