Y-axis jogging backwards

I am running a 6550-PRO with LightBurn. I installed a new YoraHome Control box and the X-axis works as it should. However, the Y-axis runs backwards. Press the forward arrow and the Y goes back, press the back arrow and the Y goes forward. I have checked the wire connections and they are correct. Is the something in GRBL settings that need changing?

NOTE; I think I found my answer. Looks like I need to set $3=2.Going to change that when the current burn is done.

YUP!! That fixed it.

With the new pro, you shouldnt uave had to change any settings, however, if it solves the problem, all should be well.

I’m not sure how it got changed but as soon as put $3=2 life was good again!
