@fcwilt Thank you very much, this did the trick!
I was thinking too complicated. Sometimes the answer can be that easy.

Hi Group, I have a problem after upgrading from RRF 2 to RRF 3. I´m using the following:
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.3 (2021-06-15)
Duet WiFi Server Version: 1.26
My Printer is a Railcore2 300zl
After the first tests, I can Home X/Y/Z individually and „home all“ without any issues. Trigerring the system to move the axis does give the right feedback in the right direction.
Performing G32 is giving me a headache. The X-achsis is trying to move negative (outside the printer to the left), whereas Y achsis seems to work properly. Here is my bed.g:
M561 ; clear any existing bed transform
G1 Z5 ; RRF3 remove S2
G30 P0 X15 Y45 Z-99999
G30 P1 X15 Y275 Z-99999
G30 P2 X275 Y275 Z-99999
G30 P3 X275 Y45 Z-99999 S3
G1 X0 Y0 Z5 F5000 ; move the head to the corner (optional)

Here is my config.g:

M555 P2 ; Set output to look like Marlin
M575 P1 B57600 S1 ; Comms parameters for PanelDue

G21 ; Work in millimetres
G90 ; Send absolute coordinates...
M83 ; ...but relative extruder moves

; Axis and motor configuration
M669 K1 ; RRF3 change M667 to M669 ; set CoreXY mode

M584 X0 Y1 Z5:6:7 E3:4:8:9 ; Map Z to drivers 5, 6, 7. Define unused drivers 3,4,8 and 9 as extruders
M569 P0 S1 ; Drive 0 goes forwards (change to S0 to reverse it) X stepper (Rear)
M569 P1 S0 ; Drive 1 goes backwards Y Stepper (Front)
M569 P2 S1 ; Drive 2 goes forwards Unused
M569 P3 S1 ; Drive 3 goes forwards Extruder
M569 P4 S1 ; Drive 4 goes forwards Extruder (unused)
M569 P5 S1 ; Drive 5 goes backwards Front Left Z
M569 P6 S1 ; Drive 6 goes backwards Rear Left Z
M569 P7 S1 ; Drive 7 goes backwards Right Z

;Leadscrew locations
M671 X-10:-10:333 Y22.5:277.5:150 S7.5 ;Front left, Rear Left, Right S7.5 is the max correction - measure your own offsets, to the bolt for the yoke of each leadscrew

Any help would be highly appreciated. I can´t find the problem myself.
