DCS Crash with 3.01-R10 / DWC 2.1.5 / DSF 2.1.1

@Garfield Wow. There is somehting going on in your environment. I can't reproduce either the M950 or config-override.g issues.

Probably a good idea to just go back to a "stable" build and wait for things to shake out a bit more. Thanks for trying anyway.

Garfield

@gtj0 I wish I knew how to just get back to a base I can trust at this stage, was fine at RC6 but it seems that even that is busted now on my box.

I've firmware erased and tried all manner of 'stuff' now, if I comment out certain lines in config.g things keep running ...

Going to blow this back to the stable release but it has problems that I couldn't live with (some of which centred on the PINDA), I also had homing issues - hence I was into the RC's - seems like something is buried in there that erase and re-imaging isn't clearing ...

gtj0

@Garfield Yeah it's frustrating I know. You may want to create an issue in the DSF GitHub repo with that crash anyway. If not, would you mind if I opened an issue on your behalf?

Garfield

Absolutely no issue at all with you adding - I suppose I should create a GIT account .... even then though I need to be sure my own incompetence isn't the cause before logging anything - so I'll still run it by here.

@Garfield https://github.com/chrishamm/DuetSoftwareFramework/issues/128

It looks like that crash is in filament monitor code. With your config.g, maybe I can reproduce it later today.

Need some place I can send you a complete copy of my backup files (they're over 5 meg)

Here are the logs from tonights blood pressure testing ... if you need more please scream before I wipe this thing again ....

haha, lets see if anything catches fire first - and i suspect you need that beer more than me atm.

Could really do with that 'version compatibility' matrix ....

Your wish, and all that. See https://forum.duet3d.com/topic/15928/new-tool-duet-v3-xx-rcx-to-apt-dsf-2-x-x-version-mapping for more info.

Meanwhile a couple of examples:

./DuetVersionsAll.sh
Expect this to take several seconds per line of output.

@Garfield I can reproduce your crash. It's the M591 command for the filament sensor. I'll add more info to the GitHub issue.

Danal

Data Point: 2.5 hour print successful, nothing else running on the Pi, most of the time disconnected from DWC.

Edit. Several more data points:

It crashed just sitting there. I only noticed after I clicked the "jobs" tab in DWC, and the file listing was blank, this was maybe an hour after the print mentioned above finished. Eventually got a "Error retrieving file list" pop up. Existing SSH session was dead. New SSH session will not connect.

I had done a "emergency stop" about an hour before the above. DWC did reconnect after that, in fact I homed the printer. Of course, that would not affect SSH, and it did not at that time.

So... No way in... Power cycle coming up.

Power cycle #1 did not bring it back. Absolutely nothing on DWC and SSH won't connect, IP of Pi does not respond to ping. HDMI and USB console shows Chromium with DWC up, but will not show, nor move, a mouse cursor. Totally hung, even on the hardware console. (The HDMI/USB was "hot plugged" after boot; this has always worked in the past.)

But interesting that it booted to Chromium and DWC before it hung. The green popup "Connected to..." was still there. It should have timed out and gone away.

Power Cycle #2 worked. DWC and SSH fine. Going to start another print.

@Danal
Yup, that sounds in-line with the sort of things I'm seeing. I wonder if your first failed power cycle was temperature related? The first time I left the crash unnoticed it cooked the Pis CPU - I noticed the smell of something warm before realising it had all crashed. After this it took a couple of resets to get things to boot normally again.
I've had occasions where it'll boot and I can SSH in with a couple of simultaneous sessions but as soon as I click connect on the DWC session on the Pi (chrome and DWC auto-load on boot), then it'll cause the crash sometimes.

Which filament sensor do you use? I have a laser one that I disconnected a few versions back as it caused another bug and because I never managed to get useful data from it. I might try re-connecting to see if it's the same bug I was seeing before as the current descriptions sound very similar.

Garfield

I use the Duet magnetic one, has worked pretty well up till now although the data reported wasn't always 'accurate'

Danal

Data point: Printing for 4.5 hours as I type this.

Filament Sensor: None.

Also, not that it should make any difference, it is a toolchanger.

chrishamm

@ChrisP Thanks for reporting this, I've been able to reproduce it and it looks like this is related to CPUSchedulingPolicy=fifo. Once that line is removed from /usr/lib/systemd/system/duetcontrolserver.service and the Pi is restarted, the problem does not seem to occur any more. So I'll remove that particular line in the next version again.

@Garfield I could reproduce your problem, too, and it will be fixed in the next DSF version. This error won't occur again in future versions. Sorry for the inconvenience.

I'm happy to help but please keep in mind that the unstable package feed is primarily for testing purposes and that bugs can occur - even though I perfectly understand they can be quite annoying. So thanks again to everyone testing it and reporting issues.

Garfield

No complaints here, apology not needed, got into the RC stream, knew the risks, happy to help diagnose and fix.

I started work on a test plan but it is kind of hard to know what to test beyond normal user interraction, when things blow up as a result of previously functional code it is hard to know how to report it, harder to know the information needed to assist in the debug / analysis / remediation.

I find it frustrating and interesting - just sometimes it is more frustration - and even then more frustration at a lack of ability to trace through the fault.

Blunt question - Is it possible to seperate the apps such that loss of DCS does not prevent access to the web console, yes I know information won't be updating but a big red status flag 'No DCS Communication' or similar could be added. Make it possible to access diagnostic logs and still be able to edit .g files from the web gui. Possibly have some 'macro' to collect basic diagnostic information for submission.

I'm not a linux fan, I don't fully understand the code, I'm trying to understand, sometimes the frustration hits the keyboard.

You want me to do some tests just reach out, I think I'm getting pretty good at switching versions in and out, which is a big thank you to all that have stepped in and helped.

chrishamm

I have just released DSF 2.1.2 which fixes both issues reported by @Garfield and @ChrisP. Please let me know if you notice any other problems.

Garfield

Other 'problems' - well not a problem but how can I get 'All' my fans to display - and I do mean all not just those allocated to a tool.

My MCU fan will not appear, the thermostatic doesn't (would be nice to have that up there with adjustable on / off thresholds).

Hows that for off topic
