I'm trying to determine how BLTouch works with Marlin.\r\n\r\nWhen running any probe operation, the pin will often tap the plate immediately after it is triggered - the build plate can't move out of the way fast enough. I figure it's one of two things:\r\n\r\n1) Once Z probe is triggered, Marlin redeploys the probe immediately.\r\n\r\n2) The BLTouch itself re-deploys the pin until it gets another command.\r\n\r\nI suspect it is `#2`, and if it is, we obviously can't change anything, except perhaps try to set the Z speed to something really fast to try and get out of the way.\r\n\r\nI did try a STOW PROBE, but that stows it too late; it's stowed just before we're ready to change XY to the next point. I also tried changing SERVO_DELAY to both 50 and 3000 to see how it affects things, but that didn't.\r\n\r\nAlso to note I don't think this has any effect on the probing... it's more a polish item. Although if the Z is too slow, it could indeed be an issue and trigger an error state on the BLTouch as it tries to deploy the pin and is not allowed to deploy the pin fully."},"comment":{"url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/comments/249023886","html_url":"https://github.com/MarlinFirmware/Marlin/issues/4855#issuecomment-249023886","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/4855","id":249023886,"user":{"login":"bgort","id":8062568,"avatar_url":"https://avatars.githubusercontent.com/u/8062568?v=3","gravatar_id":"","url":"https://api.github.com/users/bgort","html_url":"https://github.com/bgort","followers_url":"https://api.github.com/users/bgort/followers","following_url":"https://api.github.com/users/bgort/following{/other_user}","gists_url":"https://api.github.com/users/bgort/gists{/gist_id}","starred_url":"https://api.github.com/users/bgort/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/bgort/subscriptions","organizations_url":"https://api.github.com/users/bgort/orgs","repos_url":"https://api.github.com/users/bgort/repos","events_url":"https://api.github.com/users/bgort/events{/privacy}","received_events_url":"https://api.github.com/users/bgort/received_events","type":"User","site_admin":false},"created_at":"2016-09-22T20:50:05Z","updated_at":"2016-09-22T20:50:05Z","body":"Working here too!
