Slicer G code Scripts

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.

Optional

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

M420 S1 Z2; Use Level Mesh up to 2mm;

With

G29    ; Run mesh leveling on every print (non UBL)
or
G29 P1 ; Run mesh leveling on every print (UBL)

You can automatically close the mesh viewer with a C108 in a new line after the G29. For load and tilt mesh leveling in UBL use:

G29 L0 ; Load mesh from slot 0 (or use any other previously saved slot)
G29 A  ; Activate UBL
G29 J  ; Auto tilt mesh
