Bit setter not working

I just got a new Shapeoko pro XXL and I’ve been trying to get everything initialized but I’m having trouble with the Z axis. When it leaves the home position it goes to the front center prompts a bit changes, it then goes to the bit setter centers starts down and never stops until router is pushed up and Z drive crashes. I have gone through about everything I and youtube can come up with with same results. I’ve checked the wiring, all connectors, and verified every step results always the same, any suggestions

Does the light illuminate when you manually push the BitSetter button? If it does then it is correct. If it does not check where you have it plugged up.
