[BUG] Cant compile MMU2 cause idle was not declared

[Lyr3x]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

I yesterday synced to the latest bugfix-2.0.x branch (old one is about 5 month old). Triple checked the configuration changes but I can't compile marlin when uncommenting #define MMU_MODEL PRUSA_MMU2

Error:

Marlin/src/lcd/menu/menu_mmu2.cpp: In function 'void action_mmu2_unload_filament()':

#define NOZZLE_PARK_FEATURE is activated so are the advanced options like #define MMU2_MENUS

Give this a try, in Marlin/src/lcd/menu/menu_mmu2.cpp add the line #include "../../MarlinCore.h"

ie

diff --git a/Marlin/src/lcd/menu/menu_mmu2.cpp b/Marlin/src/lcd/menu/menu_mmu2.cpp
index 7e71f00d25..af3d9232b2 100644

+#include "../../MarlinCore.h"
 #include "../../feature/mmu/mmu2.h"
 #include "menu_mmu2.h"
 #include "menu_item.h"

It compiles, but I can't test it

[Lyr3x]

That was an easy one at least compilation is done without errors. Ill test that later today and update. Ty for the hint!

[Lyr3x]

Didnt print anything but communication with the MMU is working fine. Tested loading and unloading of filament. Should i provide a PR?

[ellensp]

Go for it.

[ellensp]

Since this still hasn't been created I have done it.
