Octoprint plugin to use OctoPrint's built in alerting system to notify users about "Printer Waiting for user" messages.




Install via the bundled Plugin Manager or manually using this URL:


  • Will bring up a standard alert in octoprint when the printer is waiting for your input.
  • Configurable alert severity, from "Error" and "Warning", to "Info", and "Sucess"
  • Set alerts to auto-hide, or to stay on screen
  • Note: For printer like the Prusas that repeatedly give the same message while waiting, I strongly recommend leaving this set to Auto Close.
  • Optionally can speak the alerts as well (not supported in all browsers)


  • This plugin was designed to work with the Prusa i3 Mk3s MMU2 3D printer, and will likely work with other Prusa printers as well.
  • It will work with any non-prusa printers that output the same message "echo:busy: paused for user" when waiting for user input
  • For other printers that have a different waiting for user message, create an issue on github, and I'll be happy to try to implement it for those messages as well
  • this plugin might NOT work with files on the SD card. (Untested)

Thanks to jneilliii for the M117PopUp plugin this was heavily based on, you can access it at

You can’t perform that action at this time.
