Any sort of command history available with SBC?

[tristanryerparke]

I'm having trouble setting up M28/M559 on my Duet36HC + Pi4.
The goal is to track issues during jobs/macros that are occurring while I am not connected to DWC. In a perfect world I would like to see every command sent (including those inside a macro) in a text file so that I can debug the issue.
In my config.g I have the following lines:

M28 "0:/sys/history/history1.gco"
M559 P"0:/sys/history/history2.gco"

I am using M559 because M28 seems only to write the file, and not to fill it with any lines of code that are sent via macro, file or terminal. This post seemed to be a fix/alternative:
https://forum.duet3d.com/topic/17991/m28-writing-file-with-comments-possible
The M559 command seems to do nothing at all.

Does anybody with a duet3 + RPI have some kind of command history working?
Could I use an SD card in the duet3 slot instead of SBC internal storage?
Any workaround/fix/help would be appreciated.

You can change the log level of duetcontrolserver to debug (/opt/dsf/conf/config,json. That will cause it to log every gcode that is run.
You can view the logs with
sudo journalctl --unit duetcontrolserver
