Solved Duet3 + Pi DWC freezing
-
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. -
@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:
- Download and install this firmware build (upload on the System page, then confirm): https://chrishamm.io/Duet3Firmware_MB6HC.bin
- Download and install this DuetWebControl version: https://chrishamm.io/DuetWebControl-SBC.zip (upload on the System page as well)
- Stop DCS and DWS:
sudo systemctl stop duetcontrolserver sudo systemctl stop duetwebserver- Download+extract this ZIP file: https://chrishamm.io/DSF.zip
- Overwrite the files in /opt/dsf/bin
- Restart DWS and start DCS in debug mode:
sudo systemctl start duetwebserver sudo /opt/dsf/bin/DuetControlServer -l debug -rAnd check if the problem persists.

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 foundAnd 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 -
@Carlo Maybe you need to run
sudo chmod +x /opt/dsf/bin/DuetControlServerif 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.

@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!

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

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

CYour 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.

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

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

Does this have any meaning in the issues I'm having ?

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

So received my new Duet 3 yesterday so new board new cable new installation DuetPi
nothing else attached same issue works perfectly in stand alone and does everything in SBC mode but print ...If I use DuetPi it will start the print then head to the endstops but wont stop at them after a few seconds but if I build PiOs install DSF etc it heads the other way and ploughs in to the bed but at the same point everytime after a few seconds to the mm?
with the motors screeming and M122 shows no errors everything is peachy as far as the board is concerned ...Turns out its the purge line in my start code.. which works fine in standalone mode but not SBC SBC "worked" without it Huh? Quotes well A print
Is it the spacing of the lines printing at the moment so can't retry right now but like to know how it ends.
any ideas ?
; Draw arc to prime the nozzle between 6PM and 9PM on the bed edgeG1 X0 Y-175 Z0.25 F6000
G2 X-175 Y0 I0 J175 E30 F1500
G1 X-174.52
G3 X0 Y-174.52 I174.52 J0 E28 F1500
Cheers

@Carlo Interesting. I guess it doesn't like the arc.

@Carlo Can you please upload the full file?
