Move Z axis to some place (in my example it was at 25)\r\n1. Turn off printer using PSU switch\r\n1. Wait 30 seconds or more\r\n1. Turn on printer\r\n1. Z level is at 0.000. Expected to be at 25\r\n\r\nTo correct this I do Z calibration, or use Octopi to move the Z axis up to 210 (reaches top and motor keeps spinning since it things it needs to go higher), or I use the knob to move Z to 210 same as I do with Octopi"},"comment":{"url":"https://api.github.com/repos/prusa3d/Prusa-Firmware/issues/comments/390483969","html_url":"https://github.com/prusa3d/Prusa-Firmware/issues/755#issuecomment-390483969","issue_url":"https://api.github.com/repos/prusa3d/Prusa-Firmware/issues/755","id":390483969,"user":{"login":"Zaf9670","id":32344063,"avatar_url":"https://avatars1.githubusercontent.com/u/32344063?v=4","gravatar_id":"","url":"https://api.github.com/users/Zaf9670","html_url":"https://github.com/Zaf9670","followers_url":"https://api.github.com/users/Zaf9670/followers","following_url":"https://api.github.com/users/Zaf9670/following{/other_user}","gists_url":"https://api.github.com/users/Zaf9670/gists{/gist_id}","starred_url":"https://api.github.com/users/Zaf9670/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Zaf9670/subscriptions","organizations_url":"https://api.github.com/users/Zaf9670/orgs","repos_url":"https://api.github.com/users/Zaf9670/repos","events_url":"https://api.github.com/users/Zaf9670/events{/privacy}","received_events_url":"https://api.github.com/users/Zaf9670/received_events","type":"User","site_admin":false},"created_at":"2018-05-20T13:39:08Z","updated_at":"2018-05-20T13:39:08Z","author_association":"NONE","body":"The other reason for this is due to printer startup not having the stepper motors engaged. Since you could have moved the bed after shutdown.\r\n\r\nWhile it's less likely you moved your Z-axis that's another reason why I would assume it doesn't save position during shutdown or power outages. Even the power panic re-homes before resuming."}}
