"Bridge Fan On" on the first solid layer over sparse infill #1698

Open alexborro opened 10 years ago

alexborro commented 10 years ago

If you have Bridge Fan set for any value, the Fan will be turned on not only for bridges but on a first solid layer as well.

Slic3r interprets a solid layer over sparse infill as a bridge, which is not true on almost all cases. Such behavior has an evil effect on ABS and that layer will probably not bond and warp.

It would be nice not having fan on on solid layers or at least the option to disable it.

See #240

alexborro commented 10 years ago

I saw issue #240 For small nozzles (I use 0.25mm), you don't need fan or extra flow even for 10% sparse infill... But the fan on is breaking all my ABS prints.. It would be great an option in gui to choose turning the fan on or off for solid layers.

Does someone REALLY want fan on for solid layers on ABS?? Am I the only one facing ABS warping issues due fan ?? I cannot turn fan of because it is useful for bridges.. but ONLY for bridges..

As suggested by @alexborro, I've implemented a new option in my Slic3r branch to allow the user to select the infill threshold to enable/disable the bridge over infill feature. It can be defined in the Print tab, Infill item, Bridge over infill threshold option.

You can download this version from https://github.com/llluis/Slic3r (it's forked and updated from the stable branch, so, it is based on Slic3r 1.0.0RC3)

Thanks Luís, this bridge over infill is pain in the as* for ABS printing. Em 06/03/2014 19:56, "Luís Andrade" notifications@github.com escreveu:

@llluis was there a pull request for what you did? I'd like to be able to merge it into master :)

Wow, old feature request. This is still very-much needed...
