Opto endstop for 3KU delta printers by tasdan5817

Last crawled date: 3 years ago

Hello!
This is my first thing.
I have an 3KU Delta Printer and the official endstops are some microswitchses. The printer's upper frame is a 3mm aluminium plate, and the X, Y, and Z carriages are made of the same material.
I didn't like the mechanical switches, so I designed the replace parts with optical endstop.
The 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
I fixed the endstop switch to the holder (the upper parts) with 2x10mm screw.
This part jumps into place, as you can see in the picture.
The lower (moving) part is a little tricky. You need a thin plastic, or metal sheet which can slide between the two parts of endstop.
I used a thin aluminium plate, and I fixed with glue.
