Solved Duet3 + Pi DWC freezing

[chrishamm]

@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.

@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.

Cheers

@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.

[Carlo]

@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.

[Carlo]

@chrishamm

Hi Chris,

It was not possible to just reload the page as gcode files would not start it would heat as expected but on initial movement would then try to home and not recognize the endstops so I installed DSF etc from a standalone raspbian install which has fixed the freezing but not the unable to print with the same issues as above also cannot use the webcam in DWC as it causes DWC to restart with out displaying error on each attempt though I can view the Pi cam from the web browser.
This is on 3.1.1 as per apt get.

Cheers

@Carlo

Hi Chris DC,

Any update on a fix for this minor issue ?

Cheers

this minor issue ?

Sorry what's the minor remaining issue in a nut shell?

[Carlo]

@Phaedrux

That when G-code is loaded it results in unexpected movement at the start of a print like the nozzle being plowed in to the bed or homed with the carriages crashing at the end stops and without the Pi files print as expected.

Cheers
C

[Carlo]

@Phaedrux

Does this have any meaning in the issues I'm having ?
7/14/2020, 2:05:13 PM Warning: Firmware halted
7/14/2020, 2:05:13 PM Warning: Lost connection to Duet (Timeout while waiting for transfer ready pin)

Exactly the same issue with 2off Pi4b 1off Pi3b+ at the same point always
