These are my G-Code script's that i am using in OctoPrint with my Ender 3 Pro running the Marlin firmware.

After pause

  M83

  ; retract filament, move Z slightly upwards
  G1 Z+5 E-5 F4500

  ; absolute XYZE
  M82
  G90

  ; move to a safe rest position, adjust as necessary
  G1 X0 Y0
  
  ; disable all heaters
  {% snippet 'disable_hotends' %}
  {% snippet 'disable_bed' %}
  
  ; disable fan
  M106 S0
{% endif %}

Before resume

; check for paused state
{% if pause_position.x is not none %}
  ; enable fan
  M106 S255
  
  ; heat the nozzle
