config.g file created with RRF tool M350 Array too long error

[dlc60]

This was my best guess for a place to ask this question.
Details:
Duet 2 Maestro
F/W 3.5.1, Web 3.5.1
RRF 3.5.0
Printer: custom CoreXY with single extruder.

Problem:
I just updated my Maestro to firmware/web 3.5.1 and used the RRF config tool to build my initial config.g file.
I got this error:
Error in start-up file macro line 45: in file macro line 45 column 19: M350: array too long, max length = 0
Line 45 doesn't have an M350, but there is one near there for the extruder. (attached config.g file)

; Extruders
M584 E3 ; set extruder mapping
M350 E16 I1 ; configure microstepping with interpolation
M906 E1000 ; set extruder driver currents
M92 E764 ; configure steps per mm
M566 E120 ; set maximum instantaneous speed changes (mm/min)
M203 E7200 ; set maximum speeds (mm/min)
M201 E250 ; set accelerations (mm/s^2)

My last RRF config file for another printer was from a prior version of RRF and this looks different, I am scratching my head. Can anyone see what is going wrong?

Any hint appreciated. Be well,
DLC

Can you share your config.json file as well?

@dlc60 I just updated my Maestro board with 3.5.1, and copied your config.g in to test it. I don't see this error, either at startup or if I run M98:

M98 P"config.g"
HTTP is enabled on port 80
FTP is enabled on port 21
Warning: Heater 0 predicted maximum temperature at full power is 321°C

I think this is more likely to be an SD card reading issue, maybe a bad block on the SD card. Try reformatting the SD card, or try a new one, and copy the configuration files fresh back on to it. See https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card for formatting and SD card structure guidance.
