Z Axis Calibration issue

I have set up the machine and seem to be ready to go.

I have installed the new firmware in the Arduino Duo
I have double checked the boards are connected correctly
I have triple checked that the cables are in the correct ports and properly seated.

When I get to the Z axis test calibration, the sled just moves towards the ground of my shop and does not seem to want to stop.
I pause it and then I tried to jog the sled up the Y axis away from the floor of my shop, it resumed moving to the ground of my shop.

I have tried a number of trouble shooting things I read on this forum, but I now have the sled a few inches away from the ground and am not sure what else to do.

Thank you for your assistance.

This is now resolved- The solution is in this video… where it said it would be :slight_smile:
