GRBL Settings

Hello!  I just got my machine and am trying to run a test of the Mill Right CNC test file.  With the router off, it seems to be carving upside down and backwards.  Any ideas what would cause this?

I have no problems homing the machine.

UGS platform has settings that you can use to reverse axis direction.

check the connections of the motors to the stepper drivers. They may be upside down.
