startup g-code for 7s startup

;===== BAMBU LAB P2S EXTREME START v2 =====
; Assumes the correct filament is ALREADY LOADED in the nozzle.
; No AMS loading/switching, nozzle cleaning, bed leveling,
; flow calibration, plate detection, vibration test or sensor checks.
; Expected startup is mainly limited by bed/nozzle heating.
; Test under supervision. Keep the original profile as backup.
