Filament Force Sensor

This is a Bowden filament force sensor that can be used to explore details of your printer setup.
It comprises:
Two 10kg load cells ( Size:80x12.7x12.7mm)(M4one end, M5 at the other end)
Two M5 Pneumatic couplers
One HX711 ADC module
One NodeMCU V2.
Two 28mm M4 bolts plus screws.

The code for the NodeMCU can be found here: https://github.com/dagnall53/dEEbugger_PUBLIC/tree/patch-2


Use 28-30mm screws to connect the two sensors, and 8mm screws to connect the "opposite" housing.

To use with the current code, program your NodeMCU with my version of the deeBugger software, and allow it to log into your network- the code uses WIFI Manager, so passwords etc are not stored in the Arduino sketch.
Once it is running, you need to log into the deeBugger, and change channel 1 to "HX711".
provided you have everything connected right you will see a screen like the example.

You may have to change the connections to the load cells if you get negative pressure readings when ext
