zig-zaggity

Hello, I am using CuraEngine from command line to create g-code; however, when I create the G-code, it always places the prints in the top left corner of the print bed outside of the print volume (0,0 coordinates). I have tried numerous times to change values in the fdmprinter.def.json file, as suggested by others, as a means of changing print coordinates including "mesh_position_x" and "mesh_position_y" but have failed every time 😢 I have also experimented by changing "machine_center_is_zero" and "center_object" to "true" and "false" but also to no avail (this seems to have no effect on the printing coordinates). The G-code I produce has the following heading; I understand that the negative values in the header is problematic but does anyone know how to change print coordinates for the CuraEngine command line or how to fix this problem? Any help would be greatly appreciated.
