Tevo Tarantula Filament Runout Sensor Enclosure
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
I designed this to be used with the spare sensor that comes with the Tevo Tarantula kit. You can either use small screws (M2) to attach the switch, or as I do here, simply use 1.75mm filament to attach the switch to the enclosure. Screw the enclosure together with 3 **M3 x 12mm** screws and **nuts**. I used some short pieces of PTFE tubing on the ends of the enclosure, but this is by no means necessary.
Print the **filament_runout_enclosure.stl** twice. After printing you may want to sand the pieces down, so the fit together nice and flush.
I used the Z+ Port, therefore you need to set **FIL_RUNOUT_PIN** in *pins_RAMPS.h* to **19**:
#define FIL_RUNOUT_PIN 19
In *Configuration.h* search for the **FILAMENT_RUNOUT_SENSOR** define and comment it out. If you want to use the default pinout, also invert the logic of the sensor and disable the internal pullup:
#define FILAMENT_RUNOUT_SENSOR
#if ENABLED(FILAMENT_RUNOUT_SENSOR)
#define FIL_RUNOUT_INVERTING true // set to true to invert the logic of the sensor.
//#define ENDSTOPPULLUP_FIL_RUNOUT // Uncomment to use internal pullup for
filament runout pins if the sensor is defined.
#define FILAMENT_RUNOUT_SCRIPT "M600"
#endif

OpenSCAD file is attached and may be customized via Customizer in case you want to adapt…
