Firmware downgrade

Meltex

Hello!

Recently I have upgraded my Duet 3+RPi4+Toolboard to 3.2 firmware. Now I have issues (they are uder discussion here already) and would like to downgrade to 3.1. I have that old image of DuetPi and obviously can download 3.1 firmaware but I'm not sure how to downgrade the Tooldboard. Is there any instruction how to do it in proper way?

If you're using the SBC, you can specify the versions to use during an upgrade. I think this might work similar to how updates are performed after using a beta version.

Users running an unstable firmware version (for example, any 3.2beta or 3.2RC version) on Duet + SBC, run sudo apt-get update followed by sudo apt-get upgrade duetsoftwareframework=3.2.0 duetcontrolserver=3.2.0 duetwebserver=3.2.0 duettools=3.2.0 duetruntime=3.2.0 duetsd=1.1.0 duetwebcontrol=3.2.0 reprapfirmware=3.2.0-1

Instead of 3.2, use whatever version you wish.

You can then check the installed firmware versions with M122, M122 B1, M122 B2, etc.

If they are still not downgrading the tool board firmware you can place the firmware version you want to use in the sys folder and use M997 B1, etc.

@Phaedrux Hi! Thank you for reply.

I tried but without success:

pi@Voron3D:~ $ sudo apt-get upgrade duetsoftwareframework=3.1.1 duetcontrolserver=3.1.1 duetwebserver=3.1.0 duettools=3.1.1 duetruntime=3.1.1 duetsd=1.1.0 duetwebcontrol=3.1.1 reprapfirmware=3.1.1
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version '3.1.1' for 'reprapfirmware' was not found

Whatever number I put in "reprapfirmware=3.1.xxx" it always displays that version was not found. What am I doing wrong?

@Meltex use danall script to get a list of the most up to date packages.
Use the regress and specify the version you want.

What issues are you having? Right now I can't think of any issues present in firmware 3.2 that are not also present in earlier versions.

What issues are you having?

Right after upgrade I face abnormal extruder (toolboard) behavior. I could not print jobs that were successfuly printed before - it looked like extruder doesn't extrude filament, so just tiny strings of plastic were on the bed. I have this priming procedure before start of the print:

T0
G92 E0                ; Zero extruder
G0 X30 Y0 F12000
G0 Z0.3 F9000         ; Move down

G1 X230 E30 F500       ; Extrude 30mm offilament over 200mm X axis
G1 X240 F500           ; Move 10mm without extracting
G92 E0                ; Zero extruder

This code works well, I have straight line of plastic perfectly laid on the bed. But after that there was no extruded plastic at all and during printing extruder motor did strange jerking moves with long retracts so filament just didn't come out of the nozzle. After some tests I found out that it depends on slicing software - jobs sliced in Cura didn't work but sliced in S3D did. Then I realized that if I uncheck "relative extrusion" in 3 tries out of 5 I had normal extrusion and could have successful print. But right now I cannot print at all. The first layer is a total mess. Even those jobs that were printed before.

I have disassembled the extruder and changed gears in it so now it is as new one. And to be sure that my issue is related to firmware I want to downgrade to 3.1 and double check because before 3.2 I have never had any problems. I think that it could be CAN communication issues.

Please share an example gcode for each.

If the slicer produces relative extruder moves, but the firmware is set to absolute extrusion moves it would maybe produce the odd movements you are seeing.

It's best to use relative extrusion in the slicer, but there may be an erroneous command somewhere in your start gcode that changes it to absolute instead. Sharing the gcode files will let us see what is going on.

Meltex

@jay_s_uk Thanks, but something went wrong and now I it doesn't work at all.

Meltex

@Phaedrux unfortunately, I do not have saved Cura files because I used Duet plugin that sends gcode directly to Duet. I have S3D only. Test cube relative.gcode Test cube.gcode

Phaedrux

@Meltex said in Firmware downgrade:

I used Duet plugin that sends gcode directly to Duet.

Then the gcode files are still on the SD card, or in the case of the SBC mode, the virtual SD card located at /opt/dsf/sd

Meltex

@Phaedrux I know, but the folder is empty - I have cleared all jobs a couple of days ago just to be sure that nothing causes any interferention (like file was not overwritten properly). Attached you can find the same test cube sliced right now.V350_20mmTestCube_repaired.gcode

Phaedrux

So which of the gcode files you've uploaded is one that had the problem?

Phaedrux

M82 ;absolute extrusion mode
M98 P"/macros/Printing/print_start.g"
M83 ;relative extrusion mode

In your slicer start gcodes, make sure you remove any M82 commands and make sure the slicer is set to relative extruder moves and you should be good to go.

Meltex

@Phaedrux said in Firmware downgrade:

Those with relative extrusion.

Meltex

@Phaedrux said in Firmware downgrade:

Unfortunately, Cura puts M82 anyway:

And, before upgrading it worked without issues.

Phaedrux

Yes it will start with an M82 regardless, but will add the M83 as well after the start gcode.

In your prime_extruder file you should specify if you want to be in relative or absolute extrusion mode.

prime_extruder.g

G92 E0                ; Zero extruder
G0 X30 Y0 F12000
G0 Z0.3 F9000         ; Move down

G92 E0                ; Reset extruder
G1 Z1 F9000

It looks to be formatted for absolute, and has the G92 E resets, so it should work either way.

Regardless, getting back to the tool boards. Did you confirm that they were also running 3.2?

You can then check the installed firmware versions with M122, M122 B1, M122 B2, etc.

Confirm.

Phaedrux

Would you be able to capture a M122 for the mainboard and tool board after experiencing the print problems? And to share that gcode file.

Need some time. I'm reinstalling the software on RPi right now.
