I have a day job, so when filing an issue please tag me @nickmitchko in the issue so I get an email.
OctoPrint plugin that integrates with a filament sensor hooked up to a Raspberry Pi GPIO pin and allows the filament spool to be changed during a print if the filament runs out.
Future developments are planned to include multiple filament sensors and pop-ups.
Initial work based on the Octoprint-Filament plugin by MoonshineSG and [Octoprint-Reloaded] (https://github.com/kontakt/Octoprint-Filament-Reloaded/archive/master.zip) plugin by kontakt.
Using this plugin requires a filament sensor. The code is set to use the Raspberry Pi's internal Pull-Up resistors, so the switch should be between your detection pin and a ground pin.
This plugin is using the GPIO.BOARD numbering scheme, the pin being used needs to be selected by the physical pin number.
A DIY guide is in planned for new sensor users
An API is available to check the filament sensor status via a GET method to /plugin/filamentreload/status
which returns a JSON
{status: "-1"}
if the sensor is not setup{status: "0"}
if the sensor is OFF (filament not present){status: "1"}
if the sensor is ON (filament present)After installation, configure the plugin via OctoPrint Settings interface.
