Has there been any resolution to this issue? I am having the identical problem

Ordered 3 of them, got one that suffered infant mortality.

From filastruder on may 20th

Well right now it's giving me a red flash and a green blip. Like about half the duration of the red flash.
But that is with no filament going though it. (I'm doing a single color print right now.
When I do a dual filament print on my SeeMeCNC Artemis 300 it will work for a random amount of time, then completely stall the print job giving me that "Extruder 1 reports sensor not working" error that cannot be cleared or overridden to finish the print job.

If I unplug and re-plug it in I get a green light then a red light that flashes periodically.

One of my magnetic filament sensors has stopped working.

I keep getting a "Extruder 1 reports sensor not working" error and the print stops.
I have tried unplugging and reconnecting the sensor. This allowed the print to restart the first time, but not the second.
Now the printer will not print with that sensor enabled.
I have about 1.5 spools of filament though it.
