It simply replaces a servo and mechanical endstop. Configuration is the same. It works well on my Prusa. But I have recently aquired a Delta printer and started configuring the RC3 firmware. All axis and Axis endstops are triggering as normally should. Servo/Probe Pin (BLTouch) will not deploy when I issue G29 after G28 like my prusa does. So I manually deploy the pin down with M401 and move Z down while activating the probe pin. z-probe remains OPEN and does not trigger to stop Z from moving further. I tried adjusting values in the endstop section and have only been able to invert it from OPEN to TRIGGERED.  I absolutely cannot get the endstop to trigger. But on my prusa, I was able to get it to work the first time.\n\nI am not sure if it is the board I am using or if it is my configuration in the config.h. My prusa is running Ramps 1.4 and my delta is running a MKS-Mini v1.2 which is a ramps 1.4 and gt2650 combo. The only thing I had to change was the Servo Pin to Pin 7 to activate it on the board since it does not have servo pins. I am wondering if this is the issue that causes the probe to not retract and deploy when issuing a G29 command. And also I cannot get the endstop to trigger..\n\nI had it semiworking on Rich Cattell's Testing firmware but the m401 and m402 commands were not listed in the main. I had to issue the probe up and down commands before and after G29 which is not what I had in mind since my Prusa doesnt require that. \n\nAny help would be great!\n"},"comment":{"url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/comments/259603031","html_url":"https://github.com/MarlinFirmware/Marlin/issues/2914#issuecomment-259603031","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/2914","id":259603031,"user":{"login":"Anastasio77","id":23243063,"avatar_url":"https://avatars.githubusercontent.com/u/23243063?v=3","gravatar_id":"","url":"https://api.github.com/users/Anastasio77","html_url":"https://github.com/Anastasio77","followers_url":"https://api.github.com/users/Anastasio77/followers","following_url":"https://api.github.com/users/Anastasio77/following{/other_user}","gists_url":"https://api.github.com/users/Anastasio77/gists{/gist_id}","starred_url":"https://api.github.com/users/Anastasio77/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Anastasio77/subscriptions","organizations_url":"https://api.github.com/users/Anastasio77/orgs","repos_url":"https://api.github.com/users/Anastasio77/repos","events_url":"https://api.github.com/users/Anastasio77/events{/privacy}","received_events_url":"https://api.github.com/users/Anastasio77/received_events","type":"User","site_admin":false},"created_at":"2016-11-10T05:10:26Z","updated_at":"2016-11-10T05:10:26Z","body":"Hallo again,\r\nHere are thre videos describing the problem.\r\n https://youtu.be/kOeVCM9bh5Y\r\n https://youtu.be/zN5XBMBtOYY\r\nhttps://youtu.be/gFBjkMAkEbA\r\nAny ideas?\r\nThanks.\r\n "}}
