Trying out 1.23 firmware

Hi folks, I've been struggling to correctly set up my various files having gone from 1.17rc3 to the latest with my Duet 0.6.
I've overcome most of the hurdles I think but I have an issue with the nozzle height and / or extrusion. I followed the standard nozzle calibration settings but the extruder is skipping due to being too close to the bed. Is it possible somehow due to my settings the bed leveling is not being saved ?
Z axis periodically homes to below the bed -0.35, any help appreciated.

Here is my config.g

M111 S0 ; Debug off
M550 PTux3D ; Machine name (can be anything you like). With DHCP enabled connect to (example) [reprapproormerod2] (machine name with no spaces).
M551 Preprap ; Machine password (currently not used)
M540 P0xBE:0xEF:0xDE:0xAD:0xFE:0xED ; MAC Address
M552 P0.0.0.0 ; Un-comment for DHCP
;M552 P192.168.1.14 ; IP address, comment for DHCP
M553 P255.255.255.0 ; Netmask
M554 P192.168.1.1 ; Gateway, comment for DHCP
M555 P2 ; Set output to look like Marlin
G21 ; Work in millimetres
G90 ; Send absolute corrdinates...
M83 ; ...but relative extruder moves

; Axis Limits
M208 X0 Y0 Z0 S1 ; Set axis minima
M208 X230 Y210 Z200 S0 ; Set axis maxima

M906 X800 Y1000 Z800 E800 ; Set motor currents (mA)
M305 P0 R4700 ; Set the heated bed thermistor series resistor to 4K7
M305 P1 R4700 ; Set the hot end thermistor series resistor to 4K7
M569 P0 S0 ; Set X axis direction
M92 E430 ; Set extruder steps per mm
M574 X1 S2
M558 P2 ; Use a modulated Z probe
G31 Z2.9 P600 ; Set the probe height and threshold (deliberately too high to avoid bed crashes on initial setup)
M556 S75 X0 Y0 Z0 ; Put your axis compensation here
M201 X500 Y500 Z15 E500 ; Accelerations (mm/s^2)
M203 X15000 Y15000 Z100 E3600 ; Maximum speeds (mm/min)
M566 X200 Y200 Z30 E20 ; Minimum speeds mm/minute
M563 P0 D0 H1 ; Define tool 0
G10 P0 S-273 R-273 ; Set tool 0 operating and standby temperatures
;M563 P1 D1 H2 ; Define tool 1, uncomment if you have a dual colour upgrade
;G10 P1 X19 S-273 R-273 ; Set tool 1 operating and standby temperatures, uncomment if you have a dual colour upgrade

and my bed.g

M561
G30 P0 X50 Y0 H0 Z-99999
G30 P1 X50 Y200 H0 Z-99999
G30 P2 X230 Y200 H0 Z-99999
G30 P3 X230 Y0 H0 Z-99999 S

Edit : Im in the process of welding the Z arm lower and upper brackets back together, as I've found they both had cracks. Hopefully this is the cause of my woes..........

After a firmware upgrade, if you have any problems the best thing to do is to backup your old config and then got o RepRapFirmware Configuration Tool and generate a new config.
bed.g has been deprecated, if you still want to use it then use the old version of the configuration tool

If that solves your issues you can always compare your old config and the new one to move over any settings you want to keep.

Thanks for the links, i'll have a go with the new config tool.

Surprisingly after fixing the broken Z axis clamps etc its not any better extrusion wise,however the bed level seems more accurate ! unsurprisingly

Update, all seems to be working well now, certainly accurate enough to print some much needed spares.
Liking the "baby Z stepping" and the Fan control on the fly, great additions !
