Should ask what firmware are you using I use Marlin 1.1.X
Was helping a individual who custom built his 3D Printer. His complaints was his prints were a mirrored model right to left.
The X-Axis end stop was on the wrong side, and he inverted the stepper direction ect... Meaning printer would print from Right to left instead of left to Right.
If you could give more information would help.
A diagram of your printer including the end stop locations this would help, and what firmware and version.
