This article describes the menu introduced with firmware 3.13.0 for the Original Prusa i3 MK3S.
Controlling the LCD screen is done by a single control element: a rotational knob that you press to confirm the selection. By single pressing the control button on the information screen, you enter the main menu.
The reset button is placed directly under the control knob. Pressing the reset button equates to quickly toggling the power switch (hard reset). It is useful when the printer exhibits weird behavior or you see a failed print that requires immediate cancellation.
Shortcut: Quick access to Move Z-axis function - While on the Info-screen and not printing, press and hold the Control knob for 3 seconds. While printing, the same action will let you Live adjust Z (Z微調整) for the first two millimeters.
