This is a nice design. thanks for sharing it. I'm currently using a similar one, the issue i have is that it causes too much friction on the feeder. Due to the design of my printer (a flashforge creator pro) I cannot really attach it right behind the extruder (no space, the feeding tube moves/bends also). In your experience, can this be put right in front of the roll with little to no backlash / friction ? thank you

I have it placed between filament drier/dispenser and the extruder.
But I use geared extruder, which has plenty of power, similar to:

How can this be interfaced with Marlin?

Dear random-builder, thanks for good job!

Sorry for the basic question, but my first 3d printer is somewhere between California and Texas. I have a Tronxy X5S on the way and this is one of the many "enhancements" I want to make. My equestion, which side of the extruder should it be placed?

Thanks for any response

before the extruder

Awesome!
Please could you adapt it for this type of endstop, which is the most common?

The amplifire and led is just for indication, the common otpical endstop has the same TTL level of signal on its jack output.

Quick question. what are you encoding? The only thing I can think of is speed, since you are only using a single sensor. To measure length also, you would need a dual sensor (like you find in old mice).
