Z-Axis Endstop Faults

JRCL

My Z-axis endstop is failing to enable when I home Z, despite a basic setup. I'm not sure what I'm missing, hopefully, y'all can help me!

@JRCL said in Z-Axis Endstop Faults:

M574 Z1 S2 P"zstop"

This is wrong and should be

M574 Z2 S1 P"zstop

@jay_s_uk Whoops! Swapped my Z-value and S-value, thanks a ton
