This is an optical limit switch bed leveling setup for any anycubic or copy china brand style kossel printer that uses auto bed leveling running marlin 1.1.5 or later! The offset is 65.5 with a 10mm pin out the end. You will also have to change the max and min from -20 to +20 to -70 to -50 in the advanced config file! I used an Rc Pushrod with an end stop for a RC boat rudder for a servo. You will need to run a 5v wire to power your optical switch! I used the magnet and a 2mm countersunk wood screw 6mm long to attach my magnet.Here is a video of it in action! https://www.youtube.com/watch?v=8u0xlnVjxis
