Need help with my 3D printer (Ramps w/ marlin)

[werto165]

I'm stuck! I feel like throwing my printer at the wall... I can't get my printer to start at 0,0. I have an offset applied with M206 X-14 Y-20 Z0; when I do G1 X0 F1000; and G1 Y0 F1000; the print head goes to the corner of my bed, however whenever I use simplify3d and slice an object, I just quickly made a 20x20 mm calibration cube in fusion and then stuck it at 0,0 as you see here: https://gyazo.com/f0a69dbd69bfaf08bbb1c5fcebbbaae2

However, when I go to slice my object, simplify 3D decides that it wants to start with a 43mm X offset.

Does anyone know how I can fix this. I would double check the marlin configuration files but I've somehow managed to misplace them, is there a way to get the pre-complied code back once the firmware is on the MEGA board?

Thanks.

Have you tried other slicers?
