We have a Kobra Max here at the office and it has developed a couple of weird quirks.

Issue 1

If you go into the menu and tell the printer to run a levelling check......it puts up that screen that says to touch something metal to the hot end to begin the process. Nothing EVER happens. This used to work.

​

Issue 2:

When printing, the extruder grabs filament JUST FINE. But if you try to tell the printer to either FILAMENT IN or FILAMENT OUT when doing a filament change, the extruder does not engage and pull filament in or out.

​

I'm so confused.
