Sensor callback but no trigger state change with Orginal Anycubic Filament Sensor

[raindancer2204]

Hi,

i use Octoprint in the Version 1.3.10 on my Rasberry PI 3. I connected the Orginal Anycubic Filament Sensor Typ "NUP-LED Switch Ver 1.2" to PIN 7 on the Pi. It is the new HW Version what is uses on Chiron and I3 Mega

I wired the switch to Power 3,3Volt and Ground and GPIO4(Pin7) to the PI3.

All works fine if i check it with "gpio read 7" with or not with filament, i will get 0 or 1 from the sensor via the OS. The LED on the Sensor is also working.

I use the Filament Sensor Reloaded Plugin with this sensor. I tried it serveal times, the Printer makes Pause and i can Resume the Print. After one hour i got the following Message in the logs: "octoprint.plugins.filamentreload - INFO - Sensor callback but no trigger state change"

If i check it via OS with gpio read it works fine :-(

The Printer does not make Pause he prints and dont stops.

My Question is the Power of 3,3 Volt correct oder should i use 5 Volt?

Do we have a Workaround for this Problem?

If you need a drawing of the pi to switch connect i can share it.

Regards Raini

im having same problem . logs say sensor callback but no trigger state change looks like everything is working fine just no pause . i tried throwing a m600 gcode to see if that would work nothing
