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

This worked for me. But the pin out on the 5pin side didn’t match the pictures on Prusa doc. I moved the white wire from pin 5 to pin 4 to match what Prusa manuals show. I bet it wouldn’t work otherwise.

I purchased 3 kits and I MISTAKENLY thought the magnets were not included. They ARE included and just tucked in a slot cut in the foam. Changing review to 5 stars and will buy again.

it was just as describe everything was in package and the instructions was very helpful .

This also was not damaged work perfectly good

This worked will on the Prusa MK2 to MK2.5S upgrade with the Rambo 13a board. There were slots on the board for the connectors. It is nice to have an autoload feature on the printer. Fit very well into the printed extruder housing and all the parts are in this kit for the upgrade.

I wish I saw this here before purchasing the upgrade kit from Prusa. Quick back story: Since I bought my MK3 I have never had any luck with their filament sensors working for long. I think I went through 4 in one year. Then they upgraded to the MK3 to MK3S with a new sensor. I upgraded the 1st of June and the new sensor lasted about a month. As soon as I put this new filament sensor in it worked right away. Now time will tell. I see another reviewer mentioned an issue with the cable, I reused the one that came with my upgrade kit.

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

I followed the instructions to upgrade the mk3 to mk3s and the s requires a shorter ptfe tube which is not included.

I have an orginal one from prusa as well. This one works the same no problems so far. Used up all my left spool filament just to test. Working as intended.

Like the title. first it was intermittent. Then it didnt work and i powered it with a bench top power supply and it was dead. Amazon though, full refund, cant complain. Just going to pay double and get the prusa made one. Too bad, most others seem to have had really good results. Excited to a get a run out sensor working soon!
