Cura: master branch crash

[smartavionics]

Just updated uranium, cura & curaengine master branches and now I get this:

[smartavionics]

The crash is caused by something from fb87b73 to 01437b2 my guess is something in f48539c is causing the problem?

[LipuFei]

@smartavionics Is your currently active machine a single-extrusion machine? In this PR #2685, all machines will have >= 1 ExtruderStacks, even for single-extrusion machines. From the log, looks like single extrusion machines are not upgraded properly. (probably because you were running master?)

[smartavionics]

Hi, yes, it's a single extruder printer. Can I upgrade manually?

[LipuFei]

I'm not sure if the file upgrade works yet... I will get back to you later.

[smartavionics]

OK, no problem.

[LipuFei]

@smartavionics Could you try this?

1. Open your cura folder (should be ".local/share/cura") and find the machine file in the "machine_instances" folder.
2. Open the machine file and set "setting_version" to 3.
3. Start Cura again.

[smartavionics]

Great, that worked, I changed the setting_version on two of my printers (Kossel XL and Kossel Mini) and cura started up OK. Here's what came out on the terminal if you are interested:

[LipuFei]

There is still some problems in the version upgrade... Those version outdated warning messages shouldn't occur. If you don't mind, could you pack your cura directory and send it to me? Thanks in advance!

[LipuFei]

@smartavionics Ah, now I know... Could you also downgrade all the extruder files too? just like the machine files. They are in the "extruders" folder.

[smartavionics]

Here's my master config folder. It's probably a real mess because of all the upgrades/changes that have been made as the code evolves!

mb-cura-master.zip

[smartavionics]

I did downgrade the extruders as you requested. The archive contains the files after I had downgraded and then run cura.

[LipuFei]

@smartavionics Do you still see any of those "outdated" warning messages? They should be gone now.

[smartavionics]

Yes, the're still there. But they are not a recent thing, I have been seeing those messages for quite a while now (at least weeks).

[LipuFei]

Those were built-in "Not Supported" quality profiles, which are now removed. I will test with your config folder. Thanks.

[smartavionics]

Hmm, I just realised that what I did this morning (resetting setting_version to 3 and using your latest code) made all my existing profiles go away and also all the materials went away. So I have reverted back to what I know works.

[LipuFei]

Could you pack your currently working cura folder and send it to us? The previous package wasn't very useful...

[smartavionics]

Sure, do you mean the .local/cura folder or anything else?

[LipuFei]

That's the one :)

[smartavionics]

OK, here's an updated zip, it even has a log file in it that shows some errors.
mb-cura-master.zip

[smartavionics]

Hi, any thoughts on this? I am still rather stuck because I can't use an master branch rev that is after your branch was merged (f48539c). The problems I am seeing are that all of my existing profiles go away and if I try and select another printer, cura crashes with a whole bunch of empty dialogues appearing on the screen. So, I'm screwed, really.

[LipuFei]

Hi Mark, I have tried downgrading all the files in your cura folder and things seemed to be working. No file was lost after the upgrade. Could you try the same?

I have a script here which can downgrade all the setting_versions to 3:

#!/bin/sh

new_setting_version="3"
grep -r -n setting_version ./ | cut -d':' -f1 | xargs sed -i 's/setting_version = .*/setting_version = '"${new_setting_version}"'/g'

cd to your cura folder and run this script.

[smartavionics]

It's no good, I run your script (thanks for that) and I can see that the setting_version value has changed in the files but I am still getting this crash:

Here's the log file:

cura.log.zip

[LipuFei]

I noticed that you have some custom machine definitions. Could you send those to me too? Some changes might be needed.

[smartavionics]

Here they are...

mb-printer-defs.zip

[LipuFei]

Hi Mark, I have fixed the problem with your Kossel XL. You can use this cura folder package:
mb-master-fix_01.zip

Changes:

• Changed all setting_versions to 3
• Fixed the definition container in the Kossel XL stack

If you successfully start Cura, you will still have the problem of not seeing any custom quality profiles. We are working on this at the moment and will let you know when it's done.

[LipuFei]

One thing to add: your custom profiles are there, they are just not shown on the GUI.

[LipuFei]

Hi @smartavionics , could you pull the latest master of Cura and Uranium and test it out? It should work now.

[smartavionics]

Thanks, I think it is fixed now. I can start cura without it crashing and my profiles have reappeared and I can switch between printers OK.

[LipuFei]

@smartavionics FYI, there is still some issues with custom profiles... WIP

[smartavionics]

OK

[ChrisTerBeke]

Custom profiles were just fixed by https://github.com/Ultimaker/Cura/commit/0625d22e04e00e109ace8855074a3ab687746895. Would be great if you can try it out!

[smartavionics]

I tried that and as far as I can tell, it worked OK. I can see the machines and profiles and switch between them.

[ChrisTerBeke]

Re-opening as more people seem to have the error ValueError: max() arg is an empty sequence.

[Thisismydigitalself]

After having many issues with 3.1 I am now back on 3.0.4, but it wont open my saved projects which were probably created on 3.1. Not only that but suddenly my machine settings got reset and lost and now i don't have my printer settings anymore.

i don't know what to do. this is becoming a serious issue.

[fieldOfView]

Opening a 3.1 project in 3.0 sounds like a rather bad idea, with the potential to screw up your 3.0 configuration. Cura should have a safeguard against doing that.

[Thisismydigitalself]

Trust me to not wanting to be in this situation.
I am loosing time and money over this. my mistake for trying out 3.1 beta.
learned my lesson.

[ChrisTerBeke]

It won't indeed open a newer project file (we check versions). Beta's are absolutely meant as Beta. We always recommend using the Beta alongside the previous stable (those configs can live next to each other, no problem) and not using it for any serious work. That being said this Beta had a bit more issues that we'd like ourselves...

[Thisismydigitalself]

Just reinstalled 3.1 beta and unlike the released version of 3.1, the beta runs and opens both my printer settings and projects. I hope this information will help in releasing a hotfix or 3.2 soon cause 3.1B has lots of issues.

[filipgoc]

Cura should have a safeguard against doing that.

Right!

[drewoprea]

I'm getting crashes just like you ( smartavionics ) describe: "cura crashes with a whole bunch of empty dialogues appearing on the screen." It happens some of the time when cura tries slicing a model. I get either one or two empty dialogue boxes.
I'm running Ver 3.1.0 on linux
last thing that gets written to the console is:
file:///tmp/.mount_NqVsw3/usr/bin/resources/themes/cura-light/styles.qml:197:17: QML Item: Binding loop detected for property "width"
or:
file:///tmp/.mount_wzEPtT/usr/bin/qt/qml/QtQuick/Controls/TextField.qml:638:5: QML TextInputWithHandles: Binding loop detected for property "text"

Let me know if this looks like the same bug/behavior or if i should file separately.

[smartavionics]

Hello @drewoprea , I don't think those binding loop messages are necessarily bad because you get them anyway even when cura starts OK. Can you please find your cura.log file (probably in ~/.local/share/cura/3.1 or similar) and post that (or a link to a copy), then the devs can maybe see what's happening.

[ChrisTerBeke]

Binding loops are just QT detecting that a property is being set from multiple sources or many times, and then blocking that to prevent more issues. They're not nice (as they're warnings), but not critical either. The current ones we get we couldn't figure out yet (where the property set loop is coming from).

[drewoprea]

Here's cura.log
I've found that restarting my laptop fixes the crashes for a while.
Does this log get overwritten every time I run Cura? or is this log likely to contain the conditions surrounding my dozen or so crashes?

Thanks for the quick interest!
-Drew
cura.log

Hi, I took a quick look at the file, it's cumulative so it contains all your old crashes! I think the messages of interest look like this:

Looks like it is running out of memory?

That's possible, explains why rebooting fixes it, and suggests the few times I've had the laptop hang while working were also related. This condition persisted after i restarted Cura. Is it possible that there's memory not being freed on exit? or could this be off in python somewhere, i should go double check version and such?

[smartavionics]

When the process exits all the normal memory should get freed but what may be happening is that there is some memory associated with the graphics that is getting used up and it does not get freed when the process exits. I know that on a previous Linux machine (coincidentally, also a laptop) that after running for some time (weeks) various programs would exhibit graphical glitches and rebooting always sorted it out. In fact, possibly just restarting the X server was sufficient, not sure about that.

I think the original issue has been solved so closing...
