I'm experiencing an issue with the auto homing where the Z-axis will ignore the endstop when I use the auto home button in Pronterface. Strangely, homing the axes individually I don't seem to have any issues, but when I use G28 or home the axes sequentially I observe the Z-axis motors to continue moving the gantry down despite definitely having hit the Z-endstop. Below is a link to a video demonstrating this issue:

Triggering the Z-endstop manually (with my finger) the M119 command shows "TRIGGERED". I tested, starting from a high Z position and descending towards the endstop, manually triggering the endstop (with my finger) and I observed the Z-axis motors stop.

I used Marlin Bugfix 2.0.9.3.x preconfigured release from BTT's GitHub corresponding to this board (BTT SKR 3 EZ), only changing things like motor direction and build area so as to correspond to the printer.

I am able to copy/paste the configuration.h file if that will help.

For anyone looking I figured out what the issue was. Turns out that I had miswired the JST connectors coming from the switch to the board, having not double-checked and proceeding to connect wires to the board from the switch based on the color of the wires and my assumptions (black to ground, red to VCC, other color to signal). Actually for my switches black was VCC, red was signal, and the other color was ground. Thankfully it seems the board isn't worse for wear despite my errors in wiring previously, and now the printer is functional.
