AOverview :

“Before I reached this solution, I tried many sensor types and sensing methods; in the end, this is the final solution I considered most suitable for this purpose.

As you can see in the pictures, it uses a special push-button (like the ones used in computer mice, rated to over five million clicks). When the filament is inserted, the 6mm steel ball pushes the button triggering a filament presence sensing. This is information is used in the firmware to launch a macro to auto-load the filament.
The unload button is connected to an input of the control board which is configured to trigger an event which starts the unload macro.

TBicolour LED to show status as follows:

  • Red – no filament detected
  • Green – filament present
  • Orange – unload button is pressed (only when the filament is present)

Please note that the filament sensing button is not a standard TACT switch. It has a different internal construction. The button movement range is about 0.7mm, the output contact is engaged @ about 0.3 mm and released @ about 0.2mm.”
