Reversed Coordinates

I am brand new to the world of CNC, and can’t wait to get started. After making many stupid mistakes while setting up my machine, I have one last issue. While the machine is finally taking commands, the coordinates are completely reversed. What should be a + is a -…… you get the idea. I obviously cannot cut anything because of this issue. Any suggestions out there among my new community? Thank you very much.

Depending on the machine, this might be easy to change in software; it’s also possible to change in hardware.
