[FR] Filament Runout Detection with OctoPrint

[Mave95]

Would be great to have Filament Runout Detection working with OctoPrint. Currently it doesn't send a Pause via Serial to OctoPrint, so it can't be detected.

IMHO this is not possible because the filament sensor runs directly over the TFT.

Hi, this is possible. ;)
Octoprint supports Host Action Commands.
You can configure this in configuration_adv.h and that should work.

/**

• Host Action Commands
• Define host streamer action commands in compliance with the standard.
• See https://reprap.org/wiki/G-code#Action_commands
• Common commands ........ poweroff, pause, paused, resume, resumed, cancel
• G29_RETRY_AND_RECOVER .. probe_rewipe, probe_failed
• Some features add reason codes to extend these commands.
• Host Prompt Support enables Marlin to use the host for user prompts so
• filament runout and other processes can be managed from the host side.
