filament sensor issue  

filament sensor issue

Filament sensor always reads 0

the filament sensor is always in a 0 state.

Worked for years

I have tried all the regular fixes

shim

wiggle

test wire continuity

verify wires correct on board and sensor

plugged all connections

Clean with air

replaced sensor

replaced  wires

replaced ball

verified magnet

flag moves as it should

dark room and test IR directly (out of the printer)

Verified the einsy board delivering 5v to IR board

contacted chat (waited a very long 10 minutes (way longer))

of course as per protocol they went through everything with no new thoughts.

So I decided to ask the community.

Any NEW thoughts ideas? Please do not suggest things already listed :))

Sadly i am coming to the point either the flag is stuck in firmware to 0?

Got disconnected and rather than wait again thought it might be better to utilize the community!

Thanks!
