Solved Duet3 + Pi DWC freezing

[jay_s_uk]

@Carlo

I could reload it but none of the buttons did anything.
Seems to be something locking the daemon file up and killing the pi side of things.

[Carlo]

@jay_s_uk
Yeah if I reloaded it worked as normal until cal or uploading gcode and the circle continued.

[Carlo]

Hi,
Connected to pi via desktop Chrome browser/and Pi screen
Still having this issue after update to 3.1.0 via apt-get
Also now get this error and constant network drops?
5/16/2020, 3:10:10 PM Failed to get file list (don't get this error on the Pi only over network)
Target drive is unmounted

No files show in system via web browser but are there on Pi screen
And still freezes after G32 or uploading gcode files may be more this is as far as I have gone on both Pi and web browser.

Cheers
C

@Carlo Can you confirm that you are on RRF 3.1.0? I haven't been able to reproduce it since that version. If it happens again, please run M122 from a serial monitor connected to the Duet 3, M122 "DSF" via the web interface, and post the outputs here.

The outputs of sudo ls -lR /opt/dsf/sd and sudo journalctl -u duetcontrolserver -e may be interesting, too (executed from a Linux terminal).

Hi Chris,

I have just installed a new image of duetpi and its the same issue file name 2020-05-15-DuetPi.img.

5/16/2020, 4:21:26 PM M122 "DSF"
=== Duet Control Server ===
Duet Control Server v3.1.0
Code buffer space: 4096
Configured SPI speed: 8000000 Hz
Full transfers per second: 31.0

duetcontrol to follow

cheers

@Carlo Thanks, that's all looking good. I am a bit puzzled why DWC shows the first volume as not mounted. May you share the output of http://duet3/machine/status too? In most browsers, you can switch to raw view somewhere at the top, which makes copy&paste easier.

Please post those outputs only after a freeze has occurred and before a (firmware) reset.

[Carlo]

@chrishamm

Hope this right

Sorry Chris I'm not sure I made this clear it freezes every time also sometimes when it echoes to the console DWC loses connection and needs me to reload the page not restart the system also I have reinstalled a number of times with the DuetPi image on brand new Sandisk Ultra SD cards always the same problem.
Just want to make sure I have given you as clear an understanding of the issue I'm having as my failing faculties possible can.

@Carlo

To rule the Pi out I swapped out the Pi4 for Pi 3B+ but has made no difference exactly the same ?
Thought it may help.

[chrishamm]

@Carlo I tried your config.g+bed.g on my test board and I haven't been able to provoke a freeze/crash using our latest builds. Can you please do the following:

1. Download and install this firmware build (upload on the System page, then confirm): https://chrishamm.io/Duet3Firmware_MB6HC.bin
2. Download and install this DuetWebControl version: https://chrishamm.io/DuetWebControl-SBC.zip (upload on the System page as well)
3. Stop DCS and DWS:

sudo systemctl stop duetcontrolserver
sudo systemctl stop duetwebserver

4. Download+extract this ZIP file: https://chrishamm.io/DSF.zip
5. Overwrite the files in /opt/dsf/bin
6. Restart DWS and start DCS in debug mode:

sudo systemctl start duetwebserver
sudo /opt/dsf/bin/DuetControlServer -l debug -r

And check if the problem persists.

[Carlo]

@chrishamm

Hi Chris,

All done as above however the last command returns:
pi@duet3:~ $ sudo /opt/dsf/bin/DuetControlServer -l debug -r
sudo: /opt/dsf/bin/DuetControlServer: command not found

And error in browser unable to connect to duet3 DCS is not started
I've redone it twice same result overwrote in Bin directory twice with the 10 file in the zip

[chrishamm]

@Carlo Maybe you need to run sudo chmod +x /opt/dsf/bin/DuetControlServer if you deleted it before.

Unfortunately I've found another issue which I am still debugging. I'll post an update here when I've fixed that.

[Carlo]

@chrishamm said in Duet3 + Pi DWC freezing:

sudo chmod +x /opt/dsf/bin/DuetControlServer

That fixed it ..as in its not freezing now

Thanks Really Appreciate Your Help!

C

[Carlo]

@Carlo
Sorry Chris I spoke to soon doing it is again

[chrishamm]

@Carlo I've been able to reproduce it and will come up with a fix shortly. In the meantime, reloading DWC when it freezes should solve your problem.

@chrishamm

Hi Chris
That's great
I don't want it to seem I'm hassling you I'm not as the standalone works fine my issue is a when ever just thought the feedback could help in general.

Thanks

Your feedback is indeed helpful. We are preparing a 3.1.1 release and it's good to get fixes for other significant bugs into it.
