OK 3DP got it. So when bed leveling is on (`M420 S1`) the machine will not move to negative Z coordinates. You can change that by disabling bed leveling (`M420 S0`).

To run an auto calibration though, and just let the machine do its thing, do this: [Is automatic level compensation working properly?](https://forum.snapmaker.com/t/is-automatic-level-compensation-working-properly/12386/17)  
Don’t use G1029P11 though, you’ll want G1029P3 for a 3x3 grid to start, or G1029P5 for 5x5. The rest is the same though.

If you follow those instructions that will also reset where Z=0 is, so the nozzle will touch the bed.
