I tried different step per units for the Z axis, different values for the encoder steps, and increasing or decreasing the bufsize but it still crashes when you continuously turn the rotary encoder in that menu... The workaround is to turn the encoder in small increments so the Z axis can keep up with the change so you can still reach the max position of the Z axis."},"comment":{"url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/comments/166210112","html_url":"https://github.com/MarlinFirmware/Marlin/issues/1166#issuecomment-166210112","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/1166","id":166210112,"user":{"login":"Deniskain3D","id":16378688,"avatar_url":"https://avatars.githubusercontent.com/u/16378688?v=3","gravatar_id":"","url":"https://api.github.com/users/Deniskain3D","html_url":"https://github.com/Deniskain3D","followers_url":"https://api.github.com/users/Deniskain3D/followers","following_url":"https://api.github.com/users/Deniskain3D/following{/other_user}","gists_url":"https://api.github.com/users/Deniskain3D/gists{/gist_id}","starred_url":"https://api.github.com/users/Deniskain3D/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Deniskain3D/subscriptions","organizations_url":"https://api.github.com/users/Deniskain3D/orgs","repos_url":"https://api.github.com/users/Deniskain3D/repos","events_url":"https://api.github.com/users/Deniskain3D/events{/privacy}","received_events_url":"https://api.github.com/users/Deniskain3D/received_events","type":"User","site_admin":false},"created_at":"2015-12-21T05:47:22Z","updated_at":"2015-12-21T05:47:22Z","body":"Hi! I found what the problem was.\r\nconfiguration_adv.h: \r\n#define MAX_CMD_SIZE 64\r\n#define BUFSIZE 32\r\nWith these parameters in the terminal indicated echo: Free Memory: 1547  PlannerBufferBytes: 1488\r\nIt's enough to turn the encoder at any speed. This is right for my mega2560. Enjoy )"}}
