Atmega8A-PU filament monitor with optical encoder for Marlin 1.1.x firmware second version.
This is the second version of https://www.thingiverse.com/thing:2262683
For this version i used parts from an old ball mouse: one encoder wheel and infrared emitter & receiver.
To facilitate filament movement i used 2 small pieces of ptfe tubing.
I splitted the monitor in 2 parts, one which can be attached to extruder and one which contain the monitor and can be mounted to the frame, for multiple use cases.
In my case sensor_support file was used to attach the monitor to "Infill 3D 75 Geared Extruder" https://www.thingiverse.com/thing:443849
The sensor_case_filament_guide & sensor_case_support are not required, their are just examples of how the filament case can be used.
Also sensor_wheel should be adjusted to your particular case.
