Idiot's Guide To Upgrading Duet Firmware

gbartsch

Aside from the firmware switching method you described in my pressure advance thread (https://forum.duet3d.com/topic/30990/can-t-run-pressure-advance-g-code/16) is the easiest way to ensure I can restore the printer to a working state to simply put aside a MicroSD card with all the working files on it, and do the upgrade on a different card (after copying the working files onto it)? I'm assuming that putting that original card back in the Duet would restore the machine to a working state if something went wrong with the upgrade?

Here is the config set I made for you based on what I understand of your printer and your existing configuration.

Thank you! I'll look through these.

Phaedrux

No the firmware is flashed to the Duet board itself. The SD card only has the configuration.

I would suggest that to start with you upload the 2.05 zip file to see how it goes, since it is still RRF2 it doesn't require any config file changes.

Fabulous! Thank you! Aside from a few settings most of the settings in the config.g file I made match yours. Where I knew I could, I moved your settings to my config.g file.

There are a few differences and I don't understand which to use. I've included the two files.

Should I disable bang-bang for the heater bed? I'm assuming yes as it is the old method?
Should I use your sensor values or mine? I'm going to run the Configuration Tool again inputting my thermistor values to see what numbers are generated.
Should I use your fan values or mine? I have the hotend fan and two part cooling fans (on on either side of the hotend).
And I've defined a second tool; is that another hotend? I have only one and wasn't sure what I was doing when I ran to the Configuration Tool so probably should not have added a second.

Crikey, I think we're almost there!!

[I'll look at the homing files soon.]

My thermistor is here:

So I entered 4267 in the Configuration Tool:

And the result was:

M308 S1 P"e0temp" Y"thermistor" T100000 B4267  ; configure sensor 1 as thermistor on pin e0temp

So I think that's the proper hotend thermistor definition?

Phaedrux

That looks correct. I thought I matched your thermistors from your config, but I think I did that manually, and then actually went back and regenerated the files but maybe didn't update the configurator with them.

[OT] It's forbidden to upload .zip files for good reason. But when It's sooo easy to trick the upload manager, it's kinda useless, don't you think?

@gbartsch Do not use bang-bang. It can cause artifacts in your prints. Follow the guide for auto tuning here

https://docs.duet3d.com/User_manual/Connecting_hardware/Heaters_tuning

At the end of tuning it will give you the full M307 command for your bed heater. Copy that over your existing M307 in config.g.

Thanks! I'm so looking forward to this firmware upgrade. It will really help to have it current.

This is the last question I have from my config.g file (I think ).

I MIGHT be starting to understand this. I think these are the right fan definitions for my setup?

I have a hotend cooling fan that should be temperature controlled and the two other are part cooling fans, which are not temperature controlled. The settings below reflect that?

; Fans
M950 F0 C"fan0" Q500                                   ; create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H1 T45                                      ; set fan 0 value. Thermostatic control is turned on
M950 F1 C"fan1" Q500                                   ; create fan 1 on pin fan1 and set its frequency
M106 P1 S0 H-1                                         ; set fan 1 value. Thermostatic control is turned off
M950 F2 C"fan2" Q500                                   ; create fan 2 on pin fan2 and set its frequency
M106 P2 S0 H-1                                         ; set fan 2 value. Thermostatic control is turned off

@gbartsch For my part cooling fan I have a few extra parameters

M106 P0 S0.0 H-1 B0.1 L0.0 X1.0

B0.1 blips the fan to 100% briefly (when it is completely off) to make sure it starts turning if you request a slow speed. L 0.0 sets a lower limit to off and X1.0 sets an upper limit to 100% speed.

For my M950 I have set Q100 as the PWM frequency for the fan. I was playing with that frequency as some of my fans were a bit noisy at Q500.

@gbartsch
It is worth mentioning (this is the idiot's guide after all) that after your upgrade all of your changes will be made through DuetWebControl (DWC). You can change config.g (or any other files whether system or jobs) on your computer and upload the new version to your Duet board via Wifi.

You can also download system files from the Duet to your computer to back them up.

I haven't taken the SD card out of my Duet for years now. So nice!

Awesome, thank you! Once I get this running with the basic config I'll try adding your extra parameters.

I got it! 'One small step for man ... .'

On to the next ..

I started the upgrade process after successfully installing RRF 2.05 and after trying to install 3.0 got this error:

I'm looking for this file and learning what to do with it.

Phaedrux

Try uploading the zip file for 3.0 a second time. That file should be part of the zip file.

gbartsch

@Phaedrux Thank you.

I tried installing 3.0 twice but got the error both times.

I found the file here: https://github.com/Duet3D/RepRapFirmware/releases/tag/1.21
... and 3.0 is installing.

It's taken 1 hour so far. Is that normal?

Not exactly. Usually less than a minute. It's safe to power cycle at this point and see where it's at. You can't brick the board with a failed firmware update. Worst case it would just need to be re-flashed over USB. In this case it may have just gotten stuck after finishing.

I did that and now the board doesn't show up. I ran an IP scan on my network and don't see it. If I can get help in the morning I'll look for a USB cable.
