Unable to home z axis #1
Description
First of all, thank you for sharing your efforts with making Klipper work with the original Snapmaker. This is just awesome and as I too have one around, I gave it a shot.
I just flashed your firmware on mine and am trying to set it up with Fluidd. Thereby I seem to be unable to home my z axis.
I used your sample printer.cfg as a starting point and saw that it is using the endstop_pin: ^!PA8
When I try homing my z axis, the printhead doesn't seem to move at all. Also I was wondering where the Snapmaker 1 has its z axis endstop switch and initially supposed it was located somewhere inside the linear module (but was reluctant to disassemble it).
Also, when trying to move it along the z axis, it only complains that it must be homed first.

How did you home your printer's z axis?
