K1 Max filament sensor triggers incorrectly

As the title says. My K1 Max started today triggering random “Ran out of filament” alarms, hence stopping the prints all the time.

I couldn’t find anything related to it anywhere, tried re-run the filament through it several times to see if maybe something was messing with the sensor but it keeps hapenning.

Any idea of what this may be caused by and how to fix it?

Have the same issue, I just unplugged the filament detector and was able to print without the sensor, I’m also searching for a fix

I just started having this issue. False filament out errors. Tried different filaments, factory reset, updated firmware. Happens randomly. Connections seem solid. Is there a defect in the hardware?

Try unplugging the sensor and see if it still happens. It might be a wiring issue or motherboard problem if it happens when unplugged

My problem is the opposite on this K1 Max. The filament sensor stopped working and does nothing when filament runs out. Printer is six months old and sensor worked for about four months…

The blue light goes on or off when you run a piece of filament through it. Tried a new replacement but same thing. I’m wondering if the issue is coming from the motherboard…
Not a big deal as it doesn’t interfere with the prints and there are no error messages…
