This is only a general suggestion; the exact parameters depend on your hardware setup and preferences. These scripts assume a standard Ender 3 V2/S1 with a bed of 220x220 mm or similar.

Note: to enable the leveling system, a valid mesh must be loaded into memory. Verify if you have a valid mesh in memory by opening the mesh viewer.

Cura G-code scripts

M140 S0 ; turn off heatbed
M104 S0 ; turn off temperature
M107 ; turn off fan
M84 ; disable motors

Optional

For run a mesh leveling on each print replace the lines:

G28 ; home all
M420 S1 Z2; Use a mesh leveling up to 2mm (a valid mesh must be loaded into RAM);

For non UBL version with:

G28 ; home all
G29 ; Run mesh leveling on every print
C108 ; Close the mesh viewer (optional)

UBL

For load the mesh leveling in UBL, use:

G28 ; home all
G29 L0 ; Load mesh from slot 0 (or use any other previously saved slot)
G29 A ; Activate UBL

For run a UBL mesh leveling on each print:

G29 P1 ; Home automatically and run mesh leveling on every print
G29 A ; Activate UBL
C108 ; Close the mesh viewer (optional)

Show layer number

To show layer number in the printer screen use this script in your Orca/Prusa/Super slicer:

;AFTER_LAYER_CHANGE
;[layer_z]
M117 Layer {layer_num + 1} of {total_layer_count}
