Exporting Gcode to Snapmaker 2.0

Good evening,
I’m a complete newbie here. I have processed an image in GIMP using Da Big Gimpin’ Plug in (V3). I open that saved image (JPEG) in LightBurn. I would like to send it straight to my Snapmaker 2.0 but don’t know if that is possible. Alternatively I have tried to Save Gcode and open in Snapmaker’s native software (which is limited at best) Luban. When I bring the file in (filenamewhatever.nc) it’s all blacked out. Any thoughts from the group?
