Inverting the Z axis.

[3DPotter]

Our limit switch is at the top of the Z rail. We are using probe switches. When the Z is finished homing its head position is 0. We want it to be 600. We are on firmware version 3.1.1 so we have changed our config.

On the old M574 command we had: M574 X2 Y1 Z2 S0

We now have:
M574 X1 S1 P"!xstop"
M574 Y1 S1 P"!ystop"
M574 Z1 S1 P"!zstop"

If I change the S1 to S2 it will not function and i get an error:
G28 Z
Error: Failed to enable endstops.

config: https://pastebin.com/PebvwA5X
home Z: https://pastebin.com/VNQYZx9D
home all: https://pastebin.com/KxFaRCVy

Please help. Thank you.

If I change the S1 to S2

Change Z1 to Z2

edit: looks like you might have the same issue with X?

Thank you. I swear I thought I had tried that. Problem fixed.
