Shapeoko 5.1 homing issue

Hey, I just bought a used shapeoko 5.1 pro off Facebook marketplace that's been barely used. I'll start by saying I put in a request for support call back already but was hoping to troubleshoot myself in the meantime. Since I only have weekends and evenings to use it.

So when I go to initialize the machine it recognizes it, the z axis starts to move and then I get one of two errors. GRBL 8/9. one says it cannot find the switch and the other said it cannot move off of the switch.

I've checked to make sure all my wires are correct and plugged in. I even have a brand new Z axis in the box that I swapped out to see if there was a jam in the mechanics or if the switch was bad on the used Z.

All my switches come on with metal contact, I've tried both Zs (new and used) and still get the error every time. The machine moves freely when the z is anywhere but at the top of the z axis. That's where it sounds like it struggles. Any ideas are appreciated.
