Duet3: Loading config.g after upload

evan38109

I'm sure this is an extra dumb question coming from a newbie to the Duet ecosystem, but I've spent an hour on it now and I'm stumped.

After uploading config.g and related files, how do you get the Duet 3 to load them?

I've:

Followed the instructions in the SBC Setup Guide. No problems, the Pi4 and Duet3 are working fine.
Created config files with the Config tool, then adapted them with the instructions in the RRF3 Overview.
Uploaded them via the web UI's System tab, as instructed in the SBC Setup Guide's section on Configuring System Files:

Is there a GCode or some such I need to run or option in the Web UI I need to run to execute the config.g file? I've even tried rebooting several times (shutdown -r now, via SSH) with no luck. The Console tab is empty save for one entry that reads, "Connected to duet3."

If it helps, my config.g is here. (Disclaimer: It's a first pass, I'm a newbie to RRF, and there are probably issues.)

Boot (the Duet, not the Pi).

Enter M999 into either of the DWC (Duet Web Console) command areas. Or power cycle.

There is a small advantage by going to the DWC "console" function and entering M999 there. This allows you to see the error messages from your config.g (if any), when DWC re-connects.

Ahh, that's what I was missing. Thank you!
