Tevo Tarantula Filament Runout Sensor Enclosure

thingiverse

I designed this to work seamlessly with the spare sensor that comes standard with the Tevo Tarantula kit. You can either use small screws (M2) to secure the switch, or as I do here, simply wrap 1.75mm filament around the switch and attach it directly to the enclosure. Secure the enclosure together with three M3 x 12mm screws and nuts. I used short pieces of PTFE tubing on the ends of the enclosure, but this is entirely optional. Print the filament_runout_enclosure.stl file twice. After printing, you may want to sand the pieces down to ensure they fit together smoothly and flush. I connected the Z+ Port, so 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 For more information about Marlin configuration, refer to [this resource](http://marlinfw.org/docs/configuration/configuration.html#filament-runout-sensor). The attached OpenSCAD file can be customized using Customizer in case you want to adapt it for a different switch or tolerances.
