post processing paus and resume

dovk179

I am working with creality cr 6 se.
I am trying to pause the extruder at a certain height in order to change filament.
Using Cura 4.8 I opened the post processing app (Extensions - post processing - Modify G-Code)![alt text](image url)

the added script is:
;added code by post processing
;script: PauseAtHeight.py
;current z: 1.1
;current height: 1.1
M83 ; switch to relative E values for any needed retraction
G1 F300 Z2.1 ; move up a millimeter to get out of the way
G1 F9000 X190 Y190
G1 F300 Z15 ; too close to bed--move to at least 15mm
M104 S200 ; standby temperature
M0 ; Do the actual pause
M300 S440 P200
M109 S200 ; resume temperature
G1 F300 Z2.1
The extrude pauses and moves as ordered but after few seconds resumes the printing.
what instruction do I have to add in order to have enough time to change the filament.

thanks
Dov

This might explain a thing or two about what you are trying to accomplish.
