What does the button do? (Ender 3 S1 PRO)

What does the button do in Ender 3 S1 PRO? What does it mean when it’s on and why can’t I turn it off after turning it on?

I have the same icon on my K1 Max and what it does is it turns off the stepper motors so you can move the print head easily by hand for adjustments, maintenance etc.

Indeed after switching on I can move the Z axis bar with my hand, Thanks. Just strange that I can’t turn them back on without turning the printer off and on again

No matter, when I pressed home it turned the engines back on, thanks a lot :slight_smile:
