Z-Axis bottoming out into the table during initialization

Hey, Im new to all of this tech stuff, but here’s my issue.

My Shapeoko Pro XXL with the 65mm spindle is set up. I have the bit setter, bit zero, and bit runner installed, not sure if I need them all installed when I perform the initialization. When I pop up Carbide Motion and set up / initialize, the X and Y don’t move, but the Z does…driving the spindle down to the table bottoming out and making a hard vibration noise. Ive checked all my homing sensors with a metal wrench, as well as followed each sensor wire to the circuit board where each sensor’s blue LED also lights up when I place a wrench in front of the sensor.

Ive tried a number of things I’ve read about in the forums, but some chats are outdated now with the updated software. There is no mechanical issue as far as a physical barrier causing the spindle to job in the wrong direction. And I did chose the correct machine / Z-plus, etc.

Anyone here have any suggestions?

Thank you in advance

Z moving the wrong way is almost always a setup issue. Please post a picture of your Z carriage.

OK, it sounds like you are doing all the right things, so it’s weird it’s going the wrong way.

Have you tried checking the inputs from inside Carbide Motion? Once you connect, you should be able to go to the Settings page without initializing. One of the tabs there has a live view of the inputs.

Looks like a Z-Plus. The SO4 HDZ and Z-Plus stepper motors run in opposite directions. So as @mhotchin said it is usually picking the wrong Z. If you picked the Z-Plus something is miswired. Just go back through setup. Open CM and power on your Shapeoko but do not initialize. Setup is at the bottom of the screen.

Yes when putting a wrench in front of each sensor, each one lights up on the carbide motion program as well.

Ok thank you, I will check that out when I get back to the shop
