IR-Sensor IR Filament Sensor with Steel Ball, Magnets, Screws Kit for 3D Printer Prusa i3 mk2.5/mk3 to mk2.5s/mk3s Upgrade

i have a am8 frame like the bear frame for prusa i am part hunting to make my anet as much a prusa mk3s as possible and this works i did have some firmware issues that i had to work out on my own like the #define FIL_RUNOUT_STATE HIGH norm is low by default its like the true/false for like everything else that why it took me 2day to find it while working on other things hope this help someone else so they dont waste time not printing

At the end of the day this product works. My two big issues were that I was missing some long bolts(maybe I lost them). I was able to find them in the Prusa spare parts bag. The second was I used a black PETG. The sensor was not triggered by the PETG plastic flag. I ended up putting a small piece of metal duct tape on the PETG flag so the sensor would see it. Everything else worked like a dream. I am happy.
