Is Object Deletion a thing with the stock Max?
Latest firmware it prompted me to install, and Creality Print 6.1. “Label Objects” and “Exclude Objects” are both checked on the slicer, but in the device view no models at all appear in the Object Deletion window.
The interface on the LCD does not have the extra little button in the corner as shown in the wiki, and I see no such commands at all on the Android Creality Cloud app.
