New shapeoko user

I am a new Shapeoko user and try to upgrade an older Shapeoko 2.
I got the x-controller and attached it ton the Shapeoko and connected the machine. The x and y-axis are moving, the z-axis does not move, the motor makes a scary noise. I also can’t get the quiet spindle to run,
Any suggestions would be very appreciated. Thanks!

Grinding noise?
If so, its probably something mechanical preventing motion.
