Plugin that uses the camera and opencv to determine if the bed matches a reference image indicating that the bed is clear and ready to start a print.
For the plugin to work properly add @BEDREADY at the beginning of your slicer's start gcode. As of version 0.2.0 you can also pass a filename and match percentage along with the command, @BEDREADY filename.jpg 0.8. This is helpful for having multiple reference images for different types of bed surfaces, and adding the GCODE into the filament specific start gcode settings.
TIP: For best results add gcode to your slicer's end gcode to position the head out of the way for the next comparison.
NOTE: Lighting, camera view angle changes, and filament color that is similar to the bed can impact accuracy; adjust the Match Percentage setting to compensate.
Install via the bundled Plugin Manager or manually using this URL:
https://github.com/jneilliii/OctoPrint-BedReady/archive/master.zip
Use the Test Snapshot button to compare the currently selected default Reference Image with the bed.
As of version 0.2.0 there are also plugin helpers available for other plugins to utilize the comparison functions.
def on_after_startup(self):
helpers = self._plugin_manager.get_helpers("bedready", "check_bed", "take_snapshot")
if helpers and "check_bed" in helpers:
self.check_bed = helpers["check_bed"]
if helpers and "take_snapshot" in helpers:
self.take_snapshot = helpers["take_snapshot"]
# Later in the plugin....
self.take_snapshot("new_snapshot.jpg")
self.check_bed("new_snapshot.jpg", 0.8)
