Upgrading Firmware from 2.02RC3 to 3.2

sinnedwrong

@dc42
I have just recreated firmware and specificallty ensured in the config tool to select V3.0 or later.
It provides in the zip file DuetMaestroFirmware.bin 470kb compressed size 470kb 5% ratio with a CRC 2144DF1C

@sinnedwrong and to confirm
M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2020-02-09b1

What's the way forward?

@sinnedwrong and just discovered this which could be the problem as I hadn't done this. Could be tomorrows challenge EXCEPT how easy is it to go from 3.x back to 2.05?

**Updating from RRF 2.x to 3.x
Upgrading ANY Duet 2 from 2.x to 3.0 or later requires installing 3.0 first.

The version 3.01 and later binaries are too large to be installed by the IAP program supported by version 1.x and 2.x firmware. Therefore you cannot upgrade directly from version 1.x or 2.x firmware to 3.01 or later firmware. This is the procedure:

Download file Duet2and3Firmware-3.0.zip from https://github.com/Duet3D/RepRapFirmware...
Upload and install that file on the Duet through Duet Web Control
Send M115 and check the response to confirm that you are running version 3.0 firmware
You can then upgrade to version 3.01 or later firmware.
Important! When upgrading from 1.x or 2.x firmware to 3.x you will need to make substantial changes to your config.g file. See RepRapFirmware 3 overview.**

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip
That will get your firmware and DWC up to date.

You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/Start

Backup your existing config files in the sys folder in case you want to switch back to RRF3. 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.

@phaedrux I finally got brave enough to attempt the firmware upgrade which was straightforward as I guess you are not surprised. I now have an issue in my config files. The bed which was working perfectly under 2.05 so isn't a wiring fault is coming up with the message "Heater fault rising more slowly than expected 1.8C/sec"
Settings in the RRF config tool:
tick for heated bed, bang bang,
values 120, 100, 10000,3988, 0
which are the defaults after specifying an Ormerod 2 in the initial screen. M115 gives Firmware 3.2.2 X&Y axes zero OK. That's as far as I've tested.
Ideas?

@sinnedwrong, I suggest you run heater tuning on the bed header. This will fix the fault message, also running the bed heater in bang-bang mode may cause Z banding.

sinnedwrong

@dc42 Clearly more reading and research to do however the RRF config tool was what specified bang/bang and I went with the default recommendation. Clearly I will now have to read https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control and discover how to use heater tuning. Out of interest what is Z banding and should the config tool be updated?

Thanks

Phaedrux

Well the config tool can't do the tuning for you, so even if you didn't select bang-bang there it wouldn't have any tuned PID values to use until you did a tuning cycle.

@phaedrux Just a quick reply to thank everybody, the TOY is now working successfully on 3.2.

A couple of points:
I didn't find in the change log for version 3.2 that BANG-BANG wouldn't work only that there was a new heating algorithm.
Removing the BANG-BANG option in the configuration tool might be a good idea to avoid confusion
Also for completeness it might be a good idea to change the title of this thread by adding the phrase "to 3.2". I don't think I'm allowed to do this, I suspect an admin or moderator needs to do this.

Thanks again for all the help

@sinnedwrong said in Upgrading Firmware from 2.02RC3 to 3.2:

I didn't find in the change log for version 3.2 that BANG-BANG wouldn't work only that there was a new heating algorithm.

Bang-bang can still be used. However, if you don't run heater tuning, then RRF knows nothing about your heater; so its heating rate may be lower than RRF expects, leading to a heater fault being raised.
