OctoPrint plugin that integrates with 1 or 2 filament sensors hooked up to a Raspberry Pi GPIO pin and allows the filament spool to be changed during a print if the filament runs out or is jammed.
Initial work based on the Octoprint-Filament-Reloaded plugin by kontakt.
Using this plugin requires a filament sensor and/or a jam sensor. The code is set to use the Raspberry Pi's internal Pull-Up resistors, so the switch(es) should be between your detection pin and a ground pin.
This plugin can use the GPIO.BOARD or GPIO.BCM numbering scheme.
- Configurable GPIO pins.
- Debounce noisy sensors.
- Support normally open and normally closed sensors.
- Execution of custom GCODE when out of filament detected.
- Optionally pause print when out of filament.
An API is available to check the filament sensors status via a GET method:
- to
/plugin/filamentrevolutions/filamentfor the filament sensor - to
/plugin/filamentrevolutions/jammedfor the jam sensor
{status: "-1"}if the sensor is not setup{status: "0"}if the sensor is OFF (filament not present/filament not jammed){status: "1"}if the sensor is ON (filament present/filament jammed)
- Install via the bundled Plugin Manager.
- Manually using this URL: https://github.com/RomRider/Octoprint-Filament-Revolutions/archive/master.zip
After installation, configure the plugin via OctoPrint Settings interface.
