Mainboard DET Cable

There is a cable labeled DET that runs between the extruder and the mainboard and plugs into a socket where a filament runout sensor would connect in other printers, but the SV06 of course does not have one. It’s hot glued into place so it seems Sovol really doesn’t want anyone to mess with it. Does anyone know what this does? I emailed support but they couldn’t answer my question.

If you connect a filament sensor to the empty plug on the hotend PCB, you should be able to get it working.

The filament sensor is defined in the source code:

// Filament Runout Sensor
  #define FIL_RUNOUT_PIN                    PA4   // "Pulled-high"
