Dead FINDA

A MMU2 print just failed when unloading.  I checked the Support/Sensor screen, and the FINDA value was set at 1.  There was no no filament or debris inside the loading area.  I reflashed the MMU2 with the latest firmware with no change.
I removed the FINDA entirely, and it still shows a value of 1.
But, when bending the FINDA cable, it flashes 0 occasionally.  My unit never had an LED that lit up, so I can't use that as debug.

I assume this means that the FINDA is damaged, unless someone has an idea of what it could be.  I emailed Prusa support last night, but did not get a response today.

I found a couple replacement devices in the US on Amazon

$7.99. but I am not sure this is the right part.  The description looks right.

$12.99, but there is a note that someone successfully used in a MMU2 clone   https://www.amazon.com/Taiss-LJ8A3-2-Z-Cylinder-inductive-Proximity/dp/B073XC45CC

Anyone have any suggestions here?

RE: Dead FINDA

I would suggest you contact the PR online support and let you ship a replacement (if it's really broken).

Thanks nikolai.  I tried to post a question last night, but the site rejected my question.  And I have NEVER gotten a reply when asking a MMU2 question to [email protected].  I applaud all of you who have gotten the MMU2 working, and who get responses from Prusa.  I don't want to sound like a whiner, but I am really fed up.  But, I will try the online Contact form one more time, per your suggestion.

Thanks.  I did finally get through to someone and they are sending me a replacement FINDA.
