Make M558 parameters available for more Z-Probe moves

MaxGyver

I was wondering why most of the parameters that can be configured in M558 (set Z-Probe Type) only affect G30 S0 type probing moves?

I am using a standalone Duet6XD with RRF 3.5-rc1. in CNC-mode.
This is my probe configuration

M558 K0 P5 C"io3.in" A5 H5 S0.02 F300 T3000  ; create probe #1 (toolsetter)
G31 K0 P500 X0 Y0 Z0                   ; set Z probe trigger value, offset and trigger height

When doing a G30 S0, the bed is probed at the current location until the average probed value is within the tolerance set in the S parameter or the maximum number of probes defined in the A parameter is reached. Furthermore, the first probing move is done fast, and all consecutive probing moves are done slower as defined in the Fnnn:nnn parameter. So far so good.

Now when using a different probing move like G30 S-2, M585 or G38.2 most of the before configured probe parameters have no effekt. Why are all the parameters configured in M558 not used for other probing moves as well ?

I don't use CNC mode and that may change things.

Which parameters have no effect with a G30 S-2 and why do you think they don't?

Thanks.

I will give another example

M558 K0 P5 C"io3.in" A5 H5 S0.02 F300 T3000  ; create probe #1 (toolsetter)
G31 K0 P500 X0 Y0 Z0                   ; set Z probe trigger value, offset and trigger height

When I do a G30 S-2 probing move it just stops on contact, altough the probe is configured to do up to 5 probes (A parameter) with a dive hight of 5mm (H parameter) until the average probed value is within a 0.02 mm tolerance (S parameter) .

G30 S-2 adjust the Z offset of the current tool as intended, but I would prefere if the point would be probed multiple times with the speeds, dive height and tolerances specified in M585.

EDIT: Altough I wrothe "Z-Probe moves" in the title i recon that all probing moves would benefit from multi-probing and differend dive heigths /speeds or probe recovery times.

I understand about the desire for multiple probes.

How about submitting the idea to the firmware wishlist?

@MaxGyver i use 2 kinds of probes on my CNC- an aligator clip to connect to the tool/touch-off plate for Z and a baby reinshaw type probe for X-Y.

the touch off plate will probe twice for setting Z.

the X-Y probe i think will only touch once.

I am not currently near that machine but will be over the weekend. i will try to make some experiments and report back.
