[3.5.0-b2] G31 probe offsets not working anymore

MaxGyver

I use the Euclid probe that sits 10mm below the nozzle when deployed.
When I run four screw bed leveling, the tool does not go to the set trigger height+dive height in Z but directly to the dive hight of 2mm... Or at least it tries to but there is usually a printbed in the way

I am using a Duet6HC with 3.5.0-b2

my probe configuration:

; Probe Sensor
M558 P5 C"^io4.in" H2 A3 S0.01 R0 F200 T60000	; set Z probe type and the dive height + speeds
M376 H10 ;Set height (mm) over which to taper off the bed compensation (should be 20x max mesh error)
G31 P1000 X0 Y27 Z10 ;Set Z probe parameters

And my bed.g:


T-1 ;deselect tools

M561 ;clear any bed transform
M290 R0 S0 ;clear babystepping
G92 S2 ;disable mesh compensation

M401 ;deploy probe

; probe at each corner of the bed
G30 P0 X{global.probe_Xmin} Y{global.probe_Ymax} Z-99999 ; probe near a leadscrew
G30 P1 X{global.probe_Xmax} Y{global.probe_Ymax} Z-99999 ; probe near a leadscrew
G30 P2 X{global.probe_Xmax} Y{global.probe_Ymin} Z-99999 ; probe near a leadscrew
G30 P3 X{global.probe_Xmin} Y{global.probe_Ymin} Z-99999 S4 ; probe near a leadscrew and calibrate 4 motor

while move.calibration.initial.deviation >= 0.01 ; perform additional tramming if previous deviation was over 0.01mm
	if iterations = 5
		abort "Probing cycle cancelled! Too many calibration attempts or inconsistent probe readings"
	else	
 		; repeat the probing cycle
		G30 P0 X{global.probe_Xmin} Y{global.probe_Ymax} Z-99999 ; probe near a leadscrew
		G30 P1 X{global.probe_Xmax} Y{global.probe_Ymax} Z-99999 ; probe near a leadscrew
		G30 P2 X{global.probe_Xmax} Y{global.probe_Ymin} Z-99999 ; probe near a leadscrew
		G30 P3 X{global.probe_Xmin} Y{global.probe_Ymin} Z-99999 S4 ; probe near a leadscrew and calibrate 4 motor

echo "Plattform calibration successfull. Deveation between points: " ^ move.calibration.initial.deviation ^ " mm"
M402 ;retract probe

@MaxGyver Is the way things are working now different to the way they worked before? If so what version were you running before? It's probably a good idea to post the full config.g file, it makes it easier for anyone trying to reproduce your setup.

@gloomyandy

I have tested RRF 3.4.5 stable and 3.5.0-b1. Here it works as expected. So, it is really a new issue in 3.5.0-b2.

@MaxGyver

I just noticed that for G32, G30 and G29 the probe Z-offset is applied AFTER the first probe point has been probed. All succeeding probing moves use the correct offsets.
I am on RRF 3.5.0-b2+
