First pass of bridging always droops badly, but second pass is near perfect.

Posted · First pass of bridging always droops badly, but second pass is near perfect.

Printer: Ultimaker S5
Material: Ultimaker tough PLA
Firmware: 7.1.3.0

The first strand of a bridge always has very bad drooping, but the second strand is near perfect, lost on which setting to adjust.

Using Cura slicer with experimental bridge settings enabled. Tried lower temps, lowering speed, and lowering flow rate. All seems to only apply to the strands after the first, leaving a single strand drooping from what is otherwise a very decent bridge.

    Hey @shiang1311,

     

    I think I recognize this model. It's a super thin resulting in an unfortunate bridge print in the default settings.

    You can make this printjob work better if you change 2 settings. 

    If you change the wall line count, there is enough edge to stick to the bridge.
    If you change the top layers, you don't have to deal with the pesky infill in this printjob and full bridges are generated. 

    This is my project file:

    Hope this helps 😊
