migrate config.g

[Tinchus]

Hello. I stated using duet3 conected to raspberry pi and using octoprint. Following recommendations from the forum, I decided to move into using the duet raspi and the duet control app.
My problem is: how can I copy the config.g and the other config files I already created into the new duet raspi config? If I see inspect the sd card in windows, I can only see a boot folder with the sys and the other folders inside, I tried to put there my config files but when I turn on the system, connection to the duet3 is done ok, but no heaters, motion, anything works, like if there is no configuration at all.
It looks like the config.g file I did is not being read.
How can I migrate my old config.g file into the new setup?
Thanks in advance

You can't view the raspberry pi file system on the SD card from windows.

The best way to get your config into the Duet + SBC is to download your config files and then access the Duet web control and upload your config files from there.

Does that make sense?

You can get 3rd party tools to mount the ext4 filesystem under windows, but scp/sftp is probably easier if you have network access to the pi.

(and if you have network access then the web interface as suggested is even easier)

like if there is no configuration at all.

run M98 P"config.g" from the usb console to verify if there is a problem with the config? Could be some of the old network specific config that isn't supported on the SBC is causing config to not be parsed?

hm, I just looked at the latest image and the files in /boot/sys/ aren't the same as in /opt/dsf/sd/sys?

not sure whats what; getting the network running and using duet web control is probably the safest bet.

@bearer I can confirm this. When I re-imaged my Pi I copied my config files and macros to /boot/sys/ but I still had to either upload through DWC or use VNC to copy them to the pi

[A Former User]

I don't know if the intention has been to have a firstboot like script to copy the files from /boot to /opt/dsf/sd or if the intention was to symlink from /opt/dsf/sd/sys to /boot/sys etc or what but seems it still needs some work whatever the intention.

edit seems there is a config option to choose the sd directory and its still "BaseDirectory": "/opt/dsf/sd" on the 2020-08-22-DuetPi-lite.img image.

incidentally if anyone wanna poke the image from windows before writing it to a card or something, qemu is your friend.

@bearer Windows10 with WSL2 is also an option: https://devblogs.microsoft.com/commandline/access-linux-filesystems-in-windows-and-wsl-2/

haven't tried, but hear good things. i used quemu because i wanted run the image to look for symlinks or overlays etc at runtime.

(hm, come to think of it, qemu is a good way to put ssh keys into image for headless and passwordless installs, mess with static ip setting and so on)

[Tinchus]

@Phaedrux makes sense but it is not working. go to "SYSTEM" and there I can see the config files. I uploaded my files using the UPLOAD SYSTEM FILES button, and after that did a reboot as requested. ANd the duet still is booting from some config file that is not the one being shown in the DUET CONTROL PANEL

[A Former User]

sounds unlikely, what is the output if you run the gcode M98 P"config.g" ?

[Tinchus]

@bearer it reports some errors:


Im trying to SSH to the raspi, but default user pi, passed raspberry is not working, has it been changed?

[A Former User]

Please try uploading picture again, or better, copy/paste the text.

As for ssh, no, its still the default pi / raspberry for the images i have tried at least.

@bearer I uloaded the config.g file using the interface. Something is going wrong there because Im receiving errors. I fixed most of them, but for example Im getting:
M307: error bad model parameters

But this is the same config I was using and printing with with my previous duet3/octoprint.
What is the meaning of this error?
The only M307 commands I have in my config.g is:
M307 H0 B1 S1.00 ; enable bang-bang mode for the chamber heater and set PWM limit
M307 H1 B0 S1.00 ; disable bang-bang mode for heater 1 and set PWM limit
M307 H2 B0 S1.00 ; disable bang-bang mode for heater 2 and set PWM limit

And all heaters were working ok.

[A Former User]

Hard to say without seeing the config file tbh.

But if you can fix the errors you're clearly editing the correct file no?

@Tinchus said in migrate config.g:

M350 X16 Y16 Z32 E16:16 I1 ; configure microstepping with interpolation
; M92 X160.32 Y160.32 Z3200.00:3200.00 E827.22 set steps per mm
M92 X80.16 Y80.16 Z3200.00 E428.25:428.25 ; set steps per mm

there is no point going for x32 interpolation on the z axis
x16 is more than fine.

even without interpolation you are at 0.01mm per step

The only M307 commands I have in my config.g is:

Do you also have a config-override.g present with M307 commands in it?

@Tinchus said in migrate config.g:

M501 ; load saved parameters from non-volatile memory

You can an M501 command at the end of config.g, which loads config-override.g, perhaps it's from an older version though?

Are you able to edit the config.g now? or are you still having problems with that?

Can you tell us what point you're currently at?

[Tinchus]

@Phaedrux yes, I found these lines in config-override:

M307 H0 A26.3 C284.7 D3.5 S1.00 V23.9 B0
M307 H1 A657.9 C255.6 D5.8 S0.95 V23.9 B0
M307 H2 A340.0 C140.0 D5.5 S1.00 V0.0 B0

I guess they were created after automatic tunning of heaters
Im able to edit config.g directly from the duet web control.
My actual state is kind of bad. Im getting many different errors, it is a mess actually. Im updating all software from scratch to be sure there is nothing corrupt.
My question is: my config.g file was working ok with duet3+octoprint. I was printing with on problems.
The config.g file I trying to use with duet web control is the same file, I uploaded it from the interface, why Im having these problems?

This is what I did:
.- my duet came with an SD card, that is the one Im using.
.- I updated the firmware to 3.1.1 using the windows USB connection method
.- I connected the ribbon cable.
.- Then I ran the sudo aptget update instructions I found in duet website tutorial, no errors reported.
Is this OK? do I need to update DWC too?

For example, my Z motors are not moving at all with the DWC, there was no problem with them using the same config.g and octoprint
Ideas?

[Phaedrux]

Can you please send M122 in the gcode console and post the results?

I suggest getting a fresh image of DuetPi from here and reflashing your Pi SD card.

Then doing a sudo apt update sudo apt upgrade
