Are you using a BLTouch or an IR sensor?

M558 P0 X0 Y0 Z1 H3 F200 T5000 R0 ; smart IR Z probe,

That would indicate IR probe.

M307 H3 A-1 C-1 D-1 ; BLTouch
M402 ; make sure the probe is retracted

That would indicate BLTouch.

Home Z G1 Z-300 F5000 S1 ; move quickly to X axis endstop and stop there (first pass)

That would indicate an endstop switch.

M574 X2 Y2 Z0 S0 ; Define active high microswitches

Except that would indicate no Z endstop at all.

I'm not sure how this ever worked.

@Grace-Dert said in Mirrored X axis:

M574 X2 Y2 Z0 S0 ; Define active high microswitches

In that case you should change that Z0 to Z1 (assuming it's a zmin endstop). Z0 means no endstop configured.
