; Z probe
M558 H10 A1 T3000 S0.02 ; Z probe - raise probe height.
; H10 - dive height
; A bigger dive height prevents a situation where the bed is out of alignment by more than the dive height
; on any corner, which can crash the hot-end into the bed while moving the head in XY.
; Probing speed and travel speed are similarly reduced in case the Z probe isn't connected properly (or
; disconnects later after moving to a point) giving the user more time to stop.

I'm going to change out the wires again because I found another spare; though I don't think it'll fix it, it's worth trying
