Hi,
i notice that in Simplify3d v.4.1.1 the "Extra Inflation Distance" in the Other/Bridging menu does not affect the perimeters of a bridge.
You can see this here:
As you can see in the attached factory file, "Apply bridging settings to perimeters" is activated and you can see that both perimeters and infill of the bridge are recognized as bridges. They also both use specified bridging extrusion and bridging speed multiplier. However, the "Extra Inflation Distance" is only applied to the bridge infill but not to the bridge perimeters.
This is causing a real hassle to me: when the nozzle leaves the solid "base" (green+blue in the picture above) to print the bridge infill, it immediatly slows down to bridging speed. However, the pressure inside the nozzle is still high from printing the solid "base" with higher non-bridging speed and higher non-bridging extrusion mulitplier. The slow speed and the high pressure cause the line of plastic to just sag down instead of beeing pulled across the gap.
The bridge infill works just beautifully because of the working extra inflation distance. The pressure inside the nozzle drops to bridging levels while still on the solid "base" and when the gap actually comes, speed and extrusion match perfectly so that the line of plastic is pulled across the gab without sagging down.
I believe this is a bug and should be fixed: the Extra Inflation Distance should also affect the bridge perimeters. Does anyone know if they are working on this? Does anyone know a workaround?
