Is there any issue to obtain a json response to a GET url with this plugin that send the M503 infos.
Could be interesting for me to retrieve Z-offset info for example.
You can get the data by going to http://your-ip/api/plugin/eeprom_marin
There's no guarantees I won't change the API, but it is more likely just adding more data, it is safe to use without it breaking much
I also made a one off plugin for someone here requesting this same information. More details here.
@Charlie_Powell It might be useful to mention the plugin that needs to be installed for this URL to work
Edit: After installing the plugin, OctoPrint-EEPROM-Marlin, the URL returns "Not found".
Oops, typo - the plugin id is
eeprom_marlin, I skipped the l.
That should do it. I assumed they already had the plugin installed, since it was mentioned in the post.
