I got it right. I uninstalled Cura. Reinstalled it, and when i checked to gcode in notepad, still the same problem. Then uninstalled it again, went into program files, users, user, appdata, roaming and then deleted the cura folder. ( turns out when you uninstall cura, some files are not removed) Reinstalled cura again, copy and pasted your file again. Started cura, went through all the sellecting printer exc. Went to extensions, post processing, modify gcode, selected your thumbnail v2, closed it, closed cura, started it again, sliced a model. Opened the gcode in notepad. And only your code was there๐ช๐ผ๐ช๐ผ๐๐ป๐๐ป. And now it works on the printer. ๐๐ป๐๐ป Thanks Again.
