Hello. I have a CNC with the home set up on the front right side of the machine. Because of the code to get it to home correctly, the machine cuts a mirror image of the design.
Ive tried to set up x end stop as xmax and reverse the polarity of the motor, the y axis would crash during the homing process.
Im a noob and any help is appreciated.

Also, I am not sure what you mean by ” the code to get it to home correctly,”
Did you hand code a homing sequence?
Parameter files are real tough to review via this forum tool.
Better to place the parameter dump (all of it, including the offsets section) into a Cloud drive (dropbox, Gdrive, etc) and provide a URL for viewing.I think what you want can be done, but you may need to create your Gcode design in the (-X,+Y) quadrant of the 2D design space.
