Cura Slicer - Elegoo Centari Carbon Code

Hi, see below the code:
START G CODE:

G28 ; Home all axes
M851 Z0.05 ; Apply Z offset
M500 ; Save to EEPROM
G1 Z15.0 F6000 ; Move the platform down 25mm
; Prime the extruder
G92 E0
G1 F200 E3
G92 E0

END G CODE:
; === Standard shutdown ===
M104 S0 ; turn off hotend
M140 S0 ; turn off bed
M107 ; turn off part cooling fan immediately after print
G91
G1 Z+10 E-2 F300 ; lift nozzle 10mm and retract filament slightly
G90

; Move printhead to back for easy removal
G28 X0 Y0 ; home X and Y
G1 Y250 F6000 ; move Y to back of the bed (adjust if your bed Y max is different)
G1 X20 F6000 ; move X slightly to the side so prints are easier to grab

M84 ; disable steppers

; === Cooldown Fan Sequence ===
M106 S204 ; set fan to 80% speed
G4 S600 ; keep fan running for 10 minutes
M107 ; stop fan after 2 minutes
