Klipper crashes with converted file

[DroneMang]

Hi,

I have been using arcwelder for some time and overall I would say I have had no issues, this converted file crashes the printer, causing Klipper to give an MCU shutdown, timer too close.

Here is the unconverted file and converted.

I use SolidWorks for my CAD, and when I export I use the very highest resolution settings, makes large STL/3MF files, but works well usually, perhaps I need a more coarse file? I am using Simplify3D for the slicer.

Also, I have this set in Klipper:

[gcode_arcs] resolution: 0.05 # 1.0 default

File.zip

I will take a look. Whay version are you running?

Of arcwelder? Whatever the newest that octoprint updates to, looks like 1.0.0+u.bb71e8f? I have arcwelder set to the stable release channel, I'll try dev later and recompile.

I just looked at the .aw file in S3D, I didn't see any issues. The crash happens right at the start of the print, Klipper says timer too close.

Thanks!

Ok, so I've been researching the error you observed, and it seems like it's typically a communication problem. Obviously you're not having this trouble on other files, so perhaps something else is going on? Can you take a look at the terminal output when you are trying to print that file? Maybe that will be illuminating.

If I select dev from within octoprint, will it use the 1.0.1rc1.dev2 version or do I need to manually install that?

[FormerLurker]

You would have to paste in an archive url. I can send the most recent link when i get back.

However, if you have time, see if you can replicate the error and capture the terminal output (the octoprint terminal tab). 100 lines or so should be plenty

Also, the printhead never moves from where it homes, it seems like the print starts, the START_PRINT script runs and then whatever those few commands are what make it fail.

Where should I install python 3 from? I have your command from your documentation, but there is an Octoprint link as well: https://octoprint.org/blog/2020/09/10/upgrade-to-py3/

I think I am going to install the new OctoPi image 0.18.0 RC2, which should have python 3 on it, will this be sufficient for ArcWelder?

[FormerLurker]

I think you will still need to upgrade to python 3. You can use the script you linked to. Best to run that befort installing any plugins (less to go wrong then). The command I gave installs the development tools, but the script may install that too (i suspect it does). If you can install arc welder after the upgrade, then you don't have to run the command i gave.

Also, I still need to look into your terminal log. Not been able to work on this at all since my last message, but will have time Friday at the latest. I also forgot to send you the latest install url, so here it is:

https://github.com/FormerLurker/ArcWelderPlugin/archive/cb5e62706269bce0333017d095ace93ba815535e.zip

Install via the plugin manager (get more->from url...)

I can't seem to figure this out. Looking at some other klipper issues now, so maybe it will help. Just wanted to let you know it hasn't fallen off my radar.
