I designed this Optical End Stop Switch mount & carriage flag to fit my 2020 delta printer. I also made a cover to fit over the switch to help prevent stray light affecting the sensor.
The printer started as a FolgerTech Kossel, which I upgraded to the SeeMeCNC Ball Cup Arms. Originally it used mechanical micro-switches as tower endstops; the switch to optical switches seems to provide a lower SD when running a G33 command, and there is no physical contact with the switch. The optical switches I used are made by Lerdge; specs and photo is included.
I also included the file for the carriage to work with LDO MGN 12H linear rails. These use 3mm hardware.
Make sure you run a new G33 and G29/Mesh Bed Level.
