Reverse Y axis direction Motion 640

When I attempt to initialize my machine, it moves to the lower right corner instead of the upper right corner. Then it throws a “HM08: The machine could not pull of the homing switch.” Error. How do I reverse the Y axis?

Which machine do you have?

Which Z-axis?

Reconfigure per:

https://carbide3d.com/hub/docs/shapeoko-setup/

if the Y-axis is reversed with the correct configuration, power down and swap the two Y-axis motor connectors (on an SO3 — check w/ support for other machines)

It is listed as Shapeoko XL / XXL Kit - XXL with DeWalt S3KIT-XXL-DWT on the invoice. I got it back in March of 2016.
Z axis is belt drive.

The swamping of the Y connectors fixed it.
Thank you very much for the help.
