M501 not loading config override after boot

paboman

I created two macros, each with different printer configuration for swappable print heads (PID, Max height and printer name) with M500 at the end.

At the end of config.g there is M501

If I reboot the machineconfig-override.g is not loaded, it loads the config.g instead.

What should i check ?
thx!

Firmware 2.05.1

At power on or a re-boot config.g is always loaded.

M501 just allows you to load config-override.g as well if you have commands there that need to execute.

I don't use config-override.g.

because in the docs it say:

Ensure that M501 is at the end of config.g in order for the values in config-override.g to be loaded on startup.

I understand that if M501 is in the config.g then config-override.g is loaded on startup

Hi,

As I said config.g is ALWAYS loaded.

You can chose to load config-override.g, in addition to config.g, by putting M501 at the end of config.g.

I have M501 at the end of config.g this is why I am expecting to see config-override.g loaded on startup.

Unfortunatelly config-override.g is not loading automatically on startup, trying to understand what I am doing wrong.

@dc42 can you help me please ?

Try:

M98 P"config.g"

and:

M98 P"config-override.g"

Also, can you post your config files?

how do you know config-override.g is not getting executed?

Veti

execute M98 P"config.g"

you might have errors in your config

ERRATA CORRIGE

config-override.g is loaded on startup as expected but not the printer name.

I was expecting to see also the machine name M550 changing but this command is not saved by M500.

any workaround ?

duet is not marlin.

any changes you are making should be done in config.g
these you tend to do once when you set up the printer and not change afterward.

the parameters that are saved with m500 are calibration and pid values which you tend to do a bit more often.

you will realize that duet allows to to change way more parameter whereas in marlin you would have to recompile the firmware.

i for one dont use the overwrite at all an put everything in the config.g
