Test automtic chamber grill

Hi everyone,

is there a way to test the automatic opening and closing of the chamber grill? I've upgraded my Core One to a Core One+ and now want to check if the automatic opening and closing of the grill is working correctly.

Thanks for your help!

Easiest way is to attach your computer over the USB-C port in the back and use a terminal application like Putty or CoolTerm. You can type M870 O to open and M870 C to close. Otherwise, you can save the following to a file, e.g. vent.gcode and "print" it.
