Currently the door switch is not used on these printers. A great use for it would be to detect if the door was opened between prints.
I’m not sure if I am a special kind of idiot but I frequently start my next print then have to scramble to grab my parts off the bed when I see them on the camera. The printer could simply pause and send a notification if it sees that the door has not been opened since the last print has completed.
[Print finishes] => [door opened] => [new print starts, door was opened, bed assumed clear, continue]
vs
[Print finishes] => [door hasn’t been opened] => [new print starts, door was NOT opened, pause and prompt user to make sure bed is clear]
I know the printer scans the bed with lidar to make sure the bed is clear, but it will still crash itself if you print a tall object. This would add an additional layer of protection to prevent that.
