DUET3/RRF3 config-override.g empty

[tobias_munich]

Hi,
my setup is
DUET3, current RRF3 Firmware release , RPi with the DUET3D-Image.

Issue:
whenever i do a M500 run I am getting an empty config-override.g like below.
My old PID stettings are disappeard. Is this a bug or a feature?

when you save your config (M500) did you load it bevore (M501) if not then is this the bug.

I noticed this as well. If I run M500 after heater tuning, the values in configure-overrode are empty. I had to just translate the values into my own m307 and put them in config.g

@SIam yes, I have M501 at the end of my config.g

@blt3dp this is exactly the case

There is a known bug with M500 not writing the heater parameters correctly.
@dc42 and @chrishamm are supposed to be working on it.
