Advice please on old Duet and software update

DanL

Have not been paying attention to Duet firmware updates...enjoy printing a lot but have no software savvy so ignore that. Just a hobbyist printer.
Would like to update software because I get error messages (e.g.obsolete homing command) but looks like a multi-step process to update. All functions still work despite the error messages.
Question is whether I even can update from current status and if its necessary.
Thanks for any advice.

I think the obsolete commands you're referring to is from using G1 S1 homing moves in the homing macros instead of G1 H1.

It's not too hard to update from 2.02 to the most recent and final RRF2 version of 2.05. To update beyond that would require updates to the config files and is a bit more work.

If you're happy with 2.02 and have no real issues, there's nothing forcing an update. If you just wanted to get rid of that warning on homing change the S1 to H1 in the homing macros.

What other errors are you getting?

If you do want to update and If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.

Stop here if you don't want to go through updating the config files for RepRapFirmware 3.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
That will get your firmware and DWC up to date.

You can see the change logs here:

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.

Backup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.

These documents will come in handy during the conversion.
