When moving it 100mm, there is no ramp time at all?! There is also no ramp when homing the Z axis.\r\n\r\nTo reproduce, I suggest simply decreasing your acceleration a lot so that you can clearly distinguish between ramp or no ramp by listening to the sound (or looking at the movement).\r\n\r\nThis happens since I updated from 1.1 RC3 to RC5."},"comment":{"url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/comments/211708087","html_url":"https://github.com/MarlinFirmware/Marlin/issues/3520#issuecomment-211708087","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/3520","id":211708087,"user":{"login":"thinkyhead","id":698003,"avatar_url":"https://avatars.githubusercontent.com/u/698003?v=3","gravatar_id":"","url":"https://api.github.com/users/thinkyhead","html_url":"https://github.com/thinkyhead","followers_url":"https://api.github.com/users/thinkyhead/followers","following_url":"https://api.github.com/users/thinkyhead/following{/other_user}","gists_url":"https://api.github.com/users/thinkyhead/gists{/gist_id}","starred_url":"https://api.github.com/users/thinkyhead/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/thinkyhead/subscriptions","organizations_url":"https://api.github.com/users/thinkyhead/orgs","repos_url":"https://api.github.com/users/thinkyhead/repos","events_url":"https://api.github.com/users/thinkyhead/events{/privacy}","received_events_url":"https://api.github.com/users/thinkyhead/received_events","type":"User","site_admin":false},"created_at":"2016-04-19T03:15:51Z","updated_at":"2016-04-19T03:15:51Z","body":"If anyone feels like reverting the changes that I linked to above to see how it affects behavior, that would be helpful.
