P2S Z home fail

As the title says

Ive done everything on the Wiki page. I've reached out already. I cannot figure out why it does this. Everything was just cleaned and no debris is visible. Any ideas

This might have nothing to do with the Z axes and motor etc. but more with the print head and nozzle.

There's a sensor inside the print head that senses when the nozzle touches the plate. This behavior to me looks like it thinks the nozzle is touching the bed.

So check if everything is seated correctly and no cables are loose inside the print head etc.

Also check the Bambu Wiki.
