If in your configuration h file the origin is in the middle of the plate or at 0,0 you need to set it the same way in the slicer. Go to settings in the slicer and set your origin the same way you have it in your firmware.
Also be sure that whatever axis you have inverted (usually Y) is the same in your slicer. Check for any offsets that you might have in the slicer and firmware.
