What's needed to cancel mapping before probing

stuartofmt

There have been a number of posts recently regarding probing and grid / height mapping.

My question is what is actually needed to cancel mapping. In my homez.g (and elsewhere) I use the following, but suspect some redundancy may have crept in:

; Reset all compensation
G29 S2    				; disable mesh
M290 R0 S0 				; clear baby steps
M561					; clear any transforms

Bottom line - I'm unclear as to the paractical difference between G29 S2 and M561

Thanks in advance.

@stuartofmt AFAIR G29 S2 and M561 do practically the same, i.e. turn off bed mesh compensation. In earlier days, M561 could be used to turn off n-point compensation when there was only rudimentary bed compensation support.
