When issuing code `M401` the probe deploys without raising Z. `M402` (retract) first moves the Z up with 15 then retracts the probe.  Shouldn't be the other way, or raise/ensure Z is high enough for both `M401` and `M402`? \r\n\r\n2. After performing a auto leveling (`G29 P3 V3 T`) the Z is left at an odd difference of around 7.2mm and it basically prints \"in the air\" ...\r\n\r\n3. During `G29` the probe raises more that pre-setup 5 (`Z_RAISE_BETWEEN_PROBINGS`) between the different points during probing...\r\n\r\nCan anyone explain/help?  Before doing the latest updates, I was able to print at fairly ok quality, but with very troublesome manual leveling of the bed, so I setup a servo arm to do auto leveling.\r\n\r\nConfiguration.h: http://pastebin.com/is1bQAcn\r\n"},"comment":{"url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/comments/117187696","html_url":"https://github.com/MarlinFirmware/Marlin/issues/1769#issuecomment-117187696","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/1769","id":117187696,"user":{"login":"brainscan","id":2219672,"avatar_url":"https://avatars.githubusercontent.com/u/2219672?v=3","gravatar_id":"","url":"https://api.github.com/users/brainscan","html_url":"https://github.com/brainscan","followers_url":"https://api.github.com/users/brainscan/followers","following_url":"https://api.github.com/users/brainscan/following{/other_user}","gists_url":"https://api.github.com/users/brainscan/gists{/gist_id}","starred_url":"https://api.github.com/users/brainscan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/brainscan/subscriptions","organizations_url":"https://api.github.com/users/brainscan/orgs","repos_url":"https://api.github.com/users/brainscan/repos","events_url":"https://api.github.com/users/brainscan/events{/privacy}","received_events_url":"https://api.github.com/users/brainscan/received_events","type":"User","site_admin":false},"created_at":"2015-06-30T13:39:45Z","updated_at":"2015-06-30T13:39:45Z","body":"http://www.practicalmachinist.com/vb/general/floatglass-not-flat-my-experience-216798/\r\n\r\nDepends on the glass you use, plus float glass has the same curve as the earth, nothing is perfect. \r\n\r\nSent from my iPhone\r\n\r\n> On 30 Jun 2015, at 14:20, Ovidiu Hossu <notifications@github.com> wrote:\r\n> \r\n> But it's glass... unlikely it's warped, but I will check...\r\n> \r\n> —\r\n> Reply to this email directly or view it on GitHub.\r\n> \r\n"}}
