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 part worked great. Print your own parts, keep all the screws and this is an identical upgrade to the original.

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.

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!

Was able to hook this up to my Duet board with ease. Works as it should, and fit an MK3S hotend.

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

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.

WARNING: was not wired correctly. The white, signal wire was in the wrong location. Making the item useless until the wire was placed in the right location. Works great after fix was made.

This is a complete kit. To the guy who stated that after ordering three kits, none of which had magnets, you should open up the sponge insert. The magnets are in there so that they dont interact with the steel screws and nuts. Ill update this review once I have the upgrade completed and tested.

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.

This also was not damaged work perfectly good
