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/93739187","html_url":"https://github.com/MarlinFirmware/Marlin/issues/1769#issuecomment-93739187","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/1769","id":93739187,"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":"2015-04-16T13:51:29Z","updated_at":"2015-04-16T13:51:29Z","body":"@MoonshineSG I have added code to my debug branch to raise the Z axis for `M401` and `M402` – only if needed.
