For bridges with thin layers, I think it would help a lot to extrude more or have the bridge be a thicker layer. The bridge extrusion multiplier setting in S3D doesn't allow me more than 100%.

For example, with 0.1mm layers on a 0.4mm J-Head nozzle, it is very hard to bridge, it just ends up tearing on me when 0.15mm doesn't. If I could do a 150% bridge extrusion multiplier, I can probably bridge without trouble on the thinner layer.

This is interesting, I've always looked at bridging as you want the plastic to solidify as fast as possible. Therefore having less thermal mass will help bridge the gap. The difference between how fast the plastic solidifies can be the difference between a working print and a failed print or a nice looking underside/sagging. Which is why I always print with the fan on and at lower temperatures (185ish) for PLA when doing prints that have significant bridging. Just a thought though,

I've been building with ABS and PETG. Fans just cause trouble for those materials.

I'm realizing that extruding more by itself isn't the way to go. I'm thinking that it would be nice if the initial bridges were allowed to be 2 or more layers thick for otherwise super thin layers. Maybe call it "sparse bridging".

This was fixed in version 2.0
