Clarification for M671

[dhusolo]

I'm trying to figure out what to set M671 as. I made a number of changes recently including the physical lead screw and kinematic locations.

I have a Duet 3 with RPI4 as a SBC
3 independent leveling with kinematic mounts.

My BLTouch is mounted behind and to the right of my hotend
G31 P500 X12.9 Y61.5 Z1.150

I know I need to use the kinematic mount locations in M671. My kinematic coordinates are:
X-26 Y157
X338 Y280
X338 Y26

To probe near the kinematic mounts I have
G30 P0 X52 Y187 F300 Z-99999
G30 P1 X335 Y315 F300 Z-99999
G30 P2 X335 Y61.5 F300 Z-99999 S3

But after the offset in G31 the physical nozzle coordinates are
X39.1 Y125.5
X322.1 Y253.5
X322.1 Y0

My question is for M671 do you use the coordinates in relation to the nozzle or to the probe?

@dhusolo The nozzle. The M671 are physical locations ignoring any offsets
