LCD Menu Tree

In addition to a serial/usb/host interface, Marlin also includes a menu-based user interface for inexpensive character and graphical LCD controllers. Rotate a knob or use buttons to navigate menu items, edit values, and make other adjustments. Click the knob or press a button to choose menu items, exit adjustment screens, and perform other actions.

Note: In low-level contexts we refer to the first extruder as E0, the second as E1, etc. However, at “user level” in the LCD menus, we refer to the first extruder as E1, the second as E2, etc. (Marlin 2.0 includes an option to show the first extruder as E0.)

---

The tables below describe every menu item for every option (and all 5 extruders). In normal use the LCD menu will be much smaller in size.

Move Axis

The move axis sub-menu was reorganized for Marlin 1.1. To use the move commands, first select the axis to move, then select the move distance. Use the controller wheel (or arrow buttons) to adjust the axis position. For larger move sizes, Marlin waits until you stop moving the controller for 1/2 second before it starts the move, giving you an opportunity to catch overshoot.

Item	Description	Requirements

Bed Leveling

The Bed Leveling menu groups together commands for calibrating the nozzle-to-bed distance. Different options will appear depending on your setup and the type of leveling you’ve enabled. Level Bed runs the default G29 procedure. For auto bed leveling this will deploy the probe, measure all points, and stop. For manual leveling (PROBE_MANUALLY or MESH_BED_LEVELING) you’ll be taken through a step-by-step process.

Item	Description	Requirements

Unified Bed Leveling

The Unified Bed Leveling menu groups together commands for leveling and mesh editing. Since this menu is very large and complex, it is described in a separate document.
