Downgrade from 3.2beta2 to 3.1.1

@Gio I would suggest using this.
https://github.com/DanalEstes/DuetVersions
It will give you the correct command to regress to the correct version.
But, the SPI control has changed considerably so you will first have to downgrade the firmware on the duet 3. This can be found on github

After having run apt the simplest might be to use the usb method to install the firmware

https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Updating_Duet_3_main_board_firmware
(or wrapped in a convenient script for the pi wget https://pastebin.com/raw/Wa1kYf3G -O - | tr -d "\r" | bash )

alternatively get back to 3.2, download 3.1.1 firmware and use M997 to flash the board, then use apt to downgrade the software on the pi.

sudo wget -O /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet3Firmware_MB6HC.bin
echo M997 | sudo /opt/dsf/bin/CodeConsole

Thanks a lot for your help.
I think I'm ok on rpi, I also copy my backup system folder to rpi but the error persist.

echo M997 | sudo /opt/dsf/bin/CodeConsole

Don't work:

Unhandled exception. System.Net.Internals.SocketExceptionFactory+ExtendedSocketException (99): Cannot assign requested address /var/run/dsf/dcs.sock

I never had to flash the board till now.

Thanks a lot.

Gio

I have sucsessfully downgraded from 3.2beta2 to 3.1.1.

Load mainboard Firmware version 3.1.1

sudo wget -O /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet3Firmware_MB6HC.bin

Install mainboard firmware

echo M997 | sudo /opt/dsf/bin/CodeConsole

Load expansion board firmware version 3.1.0 (optional)

sudo wget -O /opt/dsf/sd/sys/Duet3Firmware_MB6HC.bin https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.0/Duet3Firmware_EXP3HC.bin

Install expansion board firmware (Bn where n is the CAD adress of your expansion board)

echo M997 B1 | sudo /opt/dsf/bin/CodeConsole

Revert the rest:

sudo apt -y --allow-downgrades install duetsoftwareframework=3.1.1 duetcontrolserver=3.1.1 duetruntime=3.1.1 duetsd=1.0.6 duettools=3.1.1 duetwebcontrol=3.1.1 duetwebserver=3.1.0 reprapfirmware=3.1.1-1

Hi,
I tried 3.2beta2 on Duet3 with Rpi but nothing really works for me. I was unable to make a print, the Z axis moves very slowly, and the start of the print is not done correctly. The head and the bed seem to go their own way .... until the bed hits the head.

I am running Duet 3 on a CNC machine, and I have observed similar behavior exactly after updating firmware. Any idea why is this happening?

Btw, thank you for instructions how to downgrade. Now it's working just fine!

Best regards

@ErwinH78 are you sure you are running 3.2beta2 and not 3.3beta2? This is an old post and the current beta is 3.3beta2.
