CR10S pro not working pause or filament chaneg gcode.

knty

i m use m0 code(it just moves and comes back extruder. does not stop.) but not pause , or not filament change gcode..
None of the pause scripts in Cura have worked. The nozzle would move away, retract, extrude, then continue printing. If someone knows the right Gcode to use to simply pause the printer would help a lot.:

added code by post processing
;script: PauseAtHeight.py
;current layer: 2
M83 ; switch to relative E values for any needed retraction
G1 F2400 E-40
G1 F300 Z1.8399999999999999 ; 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 S195 ; standby temperature
M117 filament change
M0 ; Do the actual pause
M109 S195 ; resume temperature
G1 F2400 E40
G1 F2400 E-40
G1 F300 Z1.8399999999999999
G1 F9000 X137.756 Y42.093
G1 F300 Z0.84 ; move back down to resume height
G1 F2400 E40
G1 F2100 ; restore extrusion feedrate
M82 ; switch back to absolute E values
G92 E105.19531

when i use g25 code is stop but i cant resume print.
:
G25 ; Do the actual pause

when i use m600 nothing happens..
