 WARNING: Your printer must have a method of clearing the bed automatically, with correct GCODE instructions set up in this plugin's settings page - damage to your printer may occur if this is not done correctly. If you want to manually remove prints, look in the plugin settings for details on how to use `@pause` so the queue is paused before another print starts.
