Slic3r slows down layers so that they have time to cool, as per the settings under Filament settings -> Cooling. As an optimization, however, Slic3r could combine layer times for the current layer AND the next support layer, so that if they combined take long enough to print, there's no need to slow down.\r\n\r\nCurrently, slic3r seems to disregard the time for the support layer, so if the part's layer time is less than 15 seconds, it slows down the speed. The sequence then is:\r\n\r\n1. A part layer is printed, at reduced speed because it would take less than 15 seconds\r\n2. Then, a support layer is printed, and this is printed at high speeds because it takes 15 seconds or more to print anyway\r\n3. The next part layer is printed, again at reduced speeds\r\n4. etc...\r\n\r\nSince support layer heights are different than the part's layer height, there's a special case because there may be multiple part layers printed without any support layers in between, and in this case it's of course necessary to slow down like it currently does."},"comment":{"url":"https://api.github.com/repos/alexrj/Slic3r/issues/comments/226920045","html_url":"https://github.com/alexrj/Slic3r/issues/1853#issuecomment-226920045","issue_url":"https://api.github.com/repos/alexrj/Slic3r/issues/1853","id":226920045,"user":{"login":"lordofhyphens","id":31754,"avatar_url":"https://avatars.githubusercontent.com/u/31754?v=3","gravatar_id":"","url":"https://api.github.com/users/lordofhyphens","html_url":"https://github.com/lordofhyphens","followers_url":"https://api.github.com/users/lordofhyphens/followers","following_url":"https://api.github.com/users/lordofhyphens/following{/other_user}","gists_url":"https://api.github.com/users/lordofhyphens/gists{/gist_id}","starred_url":"https://api.github.com/users/lordofhyphens/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/lordofhyphens/subscriptions","organizations_url":"https://api.github.com/users/lordofhyphens/orgs","repos_url":"https://api.github.com/users/lordofhyphens/repos","events_url":"https://api.github.com/users/lordofhyphens/events{/privacy}","received_events_url":"https://api.github.com/users/lordofhyphens/received_events","type":"User","site_admin":false},"created_at":"2016-06-18T03:53:02Z","updated_at":"2016-06-18T03:53:02Z","body":"@alexrj did this get checked/fixed?"}}
