Describe the bug

When changing filament I pressed button on MMU3 accidentally. This causes the printer to soft lock not allowing to progress.

• Let printer unload filament
• Click continue on the screen
• Press button on MMU

Expected behavior

Printer should allow low-level controls to avoid the lock mid-print.

🤔 this looks like you've accidentally activated the Preload to MMU function by pressing the button, but I'll check it.
