so we do not have to artificially slow down general feedrates in order to account for some rare edge cases (like wide gap fill lines or really thick multi-layer infill paths)\r\n\r\n(Or am i blind for an existing solution that already does just that?)\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/alexrj/Slic3r/issues/comments/111459741","html_url":"https://github.com/alexrj/Slic3r/issues/2810#issuecomment-111459741","issue_url":"https://api.github.com/repos/alexrj/Slic3r/issues/2810","id":111459741,"user":{"login":"alexrj","id":594957,"avatar_url":"https://avatars.githubusercontent.com/u/594957?v=3","gravatar_id":"","url":"https://api.github.com/users/alexrj","html_url":"https://github.com/alexrj","followers_url":"https://api.github.com/users/alexrj/followers","following_url":"https://api.github.com/users/alexrj/following{/other_user}","gists_url":"https://api.github.com/users/alexrj/gists{/gist_id}","starred_url":"https://api.github.com/users/alexrj/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/alexrj/subscriptions","organizations_url":"https://api.github.com/users/alexrj/orgs","repos_url":"https://api.github.com/users/alexrj/repos","events_url":"https://api.github.com/users/alexrj/events{/privacy}","received_events_url":"https://api.github.com/users/alexrj/received_events","type":"User","site_admin":false},"created_at":"2015-06-12T11:29:07Z","updated_at":"2015-06-12T11:29:07Z","body":"I also agree with you -
