Converted optical Z Endstop with the adjustment disk 0.5 mm turnover.

thingiverse

The project was born out of necessity, as I found the original tuning method with a screwdriver to be less than ideal. It wasn't always feasible or private. So, I set out to create an adjustment scale and relocate the adjustment point to the fixed part, which greatly reduces errors. I chose to use an M3 screw with the standard pitch of 0.5 mm. The adjusting disk has five main divisions, each representing a 0.1 mm increment. A conventional nut with six faces is inserted into the adjusting disc for added stability. To secure the nut in place, I used a small amount of glue, varnish, or paint, keeping in mind the potential interaction between the adhesive and the printing material. The optical terminal can now be mounted universally, allowing for installation on various sides and rotation to face the connector in a convenient direction. The choice of material, print mode, and part position should be based on your experience, as I used ABS with a layer height of 0.4 mm. I opted to use the same optical endstop from the original project: https://www.aliexpress.com/item/2016-Newest-1-x-Optical-Endstop-End-Stop-Limit-Switch-Solution-for-3D-Printer-or-CNC/32656689805.html?spm=2114.search0104.3.2.66ed5316zjfnG6&ws_ab_test=searchweb0_0,searchweb201602_4_10152_10151_10065_10344_10068_5722815_10342_10343_10340_5722915_10341_5722615_10696_10084_10083_10618_10307_10820_10821_10303_10302_5722715_10059_100031_10103_10624_10623_10622_5722515_10621_10620,searchweb201603_55,ppcSwitch_3&algo_expid=a14bea03-6117-49f7-8326-d2061ce45c6a-0&algo_pvid=a14bea03-6117-49f7-8326-d2061ce45c6a&transAbTest=ae803_2&priceBeautifyAB=0
