Using cura 3.6 I can not figure out how to put a pause for filament color change. I go to modify gcode ,post processing, add a script. pick filament change . All I see is put in layer number which I can figure out. then there is initial retraction then there is later retraction. It does not work the print never stops. Some people say I am suppose to put in the command m600 but I don't know where to put it. I am using cura 3.6 on a cr 10 s pro .Thanks
