This results in broken solid infill, since: speed to to fast, often there is nothing to anchor to.\r\n\r\nIn my opinion, to get best adhesion, it should treat solid infill area as any other bridge. I.e. it first should do perimeter and then run bridge infill with appropriate speed/flow/width/etc.\r\n\r\n![infill in the air](https://cloud.githubusercontent.com/assets/361630/11580225/b543ade2-99fa-11e5-9a51-98bfc5c418ca.jpg)\r\n\r\n[ultimate_calibration_test-2015-12-3-19-48.gcode.txt](https://github.com/alexrj/Slic3r/files/51590/ultimate_calibration_test-2015-12-3-19-48.gcode.txt)\r\n\r\n[ultimate_calibration_test.STL.txt](https://github.com/alexrj/Slic3r/files/51591/ultimate_calibration_test.STL.txt)\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/alexrj/Slic3r/issues/comments/168281849","html_url":"https://github.com/alexrj/Slic3r/issues/3146#issuecomment-168281849","issue_url":"https://api.github.com/repos/alexrj/Slic3r/issues/3146","id":168281849,"user":{"login":"clough42","id":3324188,"avatar_url":"https://avatars.githubusercontent.com/u/3324188?v=3","gravatar_id":"","url":"https://api.github.com/users/clough42","html_url":"https://github.com/clough42","followers_url":"https://api.github.com/users/clough42/followers","following_url":"https://api.github.com/users/clough42/following{/other_user}","gists_url":"https://api.github.com/users/clough42/gists{/gist_id}","starred_url":"https://api.github.com/users/clough42/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/clough42/subscriptions","organizations_url":"https://api.github.com/users/clough42/orgs","repos_url":"https://api.github.com/users/clough42/repos","events_url":"https://api.github.com/users/clough42/events{/privacy}","received_events_url":"https://api.github.com/users/clough42/received_events","type":"User","site_admin":false},"created_at":"2016-01-01T04:44:30Z","updated_at":"2016-01-01T04:44:30Z","body":"I don't know if my situation is the same, but I'm seeing similar-looking failures, with unsupported extrusions ending in open space, like this:\r\n\r\n![oddbridging1](https://cloud.githubusercontent.com/assets/3324188/12069760/6eda88a8-b007-11e5-9d95-5597b2506393.PNG)\r\n![oddbridging2](https://cloud.githubusercontent.com/assets/3324188/12069762/7a070b2a-b007-11e5-8ad7-07dea2977168.PNG)\r\n![oddbridging3](https://cloud.githubusercontent.com/assets/3324188/12069761/7a053d86-b007-11e5-9da3-bb9c5e2205b3.PNG)\r\n\r\nModels and config files:\r\n\r\n[ShroudBridges2.zip](https://github.com/alexrj/Slic3r/files/75855/ShroudBridges2.zip)\r\n\r\nSorry for the blast.
