Opto endstop for 3KU delta printers
thingiverse
Hello!\nThis is my first post.\nI have a 3KU Delta Printer, and the official endstops are some microswitches. The printer's upper frame is a 3mm aluminium plate, and the X, Y, and Z carriages are made of the same material.\nI wasn't a fan of the mechanical switches, so I designed replacement parts with optical endstops. \nThe endstop I used:http://www.aliexpress.com/item/5pcs-lot-Optical-Endstop-Light-Control-Limit-Optical-Switch-for-3D-Printers-RAMPS-1-4-Free/1729261085.html?spm=2114.01010208.3.2.iWEo0d&ws_ab_test=searchweb201556_7,searchweb201602_5_10037_10017_507_10032_401,searchweb201603_2&btsid=7b263ed1-ac23-4e78-a32c-e939ab66acff\nI attached the endstop switch to the holder (the upper components) with 2x10mm screws.\nThis part clicks into place, as you can see in the picture. \nThe lower (moving) part is a bit tricky. You need a thin plastic or metal sheet that can slide between the two parts of the endstop.\nI used a thin aluminium plate and attached it with glue.
