This article describes the menu system BEFORE firmware 3.9.0 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, press and hold the Control knob for 3 seconds
Nozzle temperature (actual / desired temperature)
Heatbed temperature (actual / desired temperature)
Progress of printing in % - shown only during the printing
Status bar (Prusa i3 MK3S ready. / Heating / file_name.gcode, etc.)
Remaining time estimation
Shortcut: Quick access to change Printing speed - While on the Info-screen, spin the knob either direction, more than one rotation, and see the percentage change.
