@Hilbe, what OS do you use? The development snapshots linked above do have that issue on Linux (and possibly OSX).

I have tried this plugin on both MacOSX and Win10, and only on Win10 is G2/G3 code generated.

Did you try the version from the Marketplace, or the development snapshot I posted in this thread?

If the Marketplace version does not work on OSX, could you please share your cura.log?

[PricklyPear 3]

@ahoeben, I have the Marketplace version and I am running Cura 4.8.0.

On top of the settings, there is a search field. Do you see the settings if you type "Arc" there?

Thanks a lot for this nice plugin :-) I have a delta printer and this feature was deseperatly missing in Cura !

 

I noticed a small bug : if there are some unicode symbols in some comments (° in my case), the plugin failed to save the file with the following error :

Unable to write to file pied piano: 'ascii' codec can't encode character '\xb0' in position 43211162: ordinal not in range(12
8)

Removing the caracter solved the issue, so nothing critical, but it'd been nice to allow unicode comments anyway

Thanks for reporting. Fixed here:

I'm adding more logging to the plugin, so it will be easier to diagnose the reason why the plugin is not working.

Can I ask you to test a development snapshot?

[macmaddog 0]

Search was  the first thing  I do. There is noting showing .

 

[PricklyPear 3]

@macmaddog, have you checked that ArcWelder is installed in "Marketplace"? And that the tickbox is marked?

Yes, I would like to test a development snapshot. 

Where do I find the development snapshot? I have looked on GitHub but can't see anything.

I'll let you know when I make one, but that may not be until next year...

Hi, there is no G2/G3 in the gcode (and no reduction in gcode size) using the Marketplace version of the plugin on Cura 4.8.0, OS-X Big Sur 1.2 Beta (20D5029f).  I checked that ~/Library/Application Support/cura/4.8/plugins/ArcWelderPlugin/bin/osx/ArcWelder is 'chmod +x' and I can execute it from Terminal.

 

Also tried the dev version posted in an earlier comment (ArcWelderPlugin-v7.0.0-2020-11-30T10-46-32Z.curapackage), no difference (except I had to chmod+x the binary).

 

Attached 'tail' from cura.log during a slice--don't see anything in the log about Arc Welder other than the arc_welder settings being passed to CuraEngine.  Am I missing something?
 

I tried various settings including reducing 'Resolution' and disabling the Min Arc Segments (since I have Marlin 2.0), but no difference.

 

FWIW, the OctoPrint plugin works (proving the original gcode isn't faulty).

Here's my full cura.log, not just a snippet.

[ahoeben 1,808]

@davispw and @PricklyPear, here is a new development snapshot for you to try. I don't think it directly fixes your problem, but at least it should show more details about what is going wrong in the logs (so if you try it, a new Cura.log is appreciated).

 

@macmaddog, I really cannot help you without your log files. You can find cura.log via the Help -> Show configuration folder... menu-item.

[PricklyPear 3]

Thank you, @ahoeben, for developing this plugin.

I installed the latest development snapshot (v7.0.0-2021-01-05T11-45-39Z) and ran through a couple of stl files with ArcWelder activated. I was able to slice the files but when I tried to save the generated gcode, I received an error:

Exception: Unable to write to file Test prints for ArcWelder-Snake: Command '[<<snip>>]' returned non-zero exit status -11

So, no gcode file was available to review and I could not check if G2/G3 code was generated.

With ArcWelder option unchecked, normal gcode files were generated and the file could be saved.

AWplugin v7 cura.log

[ahoeben 1,808]

The processing does not happen until just before the gcode is saved to disk or printed. The plugin does not affect the actual slicing (which is also why the effect of the plugin will not be visible in the layerview).

 

The ArcWelder command returning an exit status of -11 means it encountered a "Segmentation vault" ("it crashed"). Hmm, I have no idea why it would crash. Let's see if pinging @FormerLurker works.

It always does 🙂

I've actually never received a segfault report for ArcWelder before.  However, I see in the log this is being generated from OSX, and I've never run on that OS before (I don't have access to it at all).  However, perhaps it could be executed from the command line with the following parameter:

--log-level=DEBUG

That should give me an idea where it is crashing at least.  The console output would need to be saved (how does one do output redirection in OSX?) and posted somewhere I can see it.

[ahoeben 1,808]

@PricklyPear could try disabling the ArcWelder setting in Cura to save a gcode file, and then manually launch the ArcWelder command from a terminal and copy/paste the output here:

 

/Users/iMac2011/Library/Application Support/cura/4.8/plugins/ArcWelderPlugin/ArcWelderPlugin/bin/osx/ArcWelder --log-level=DEBUG -m=1000000 -t=0.01 -r=0.05 -s=1.0 -a=12 path/to/file.gcode

Obviously, the path/to/file.gcode part should be replaced by a (relative or absolute) path to the saved gcode file.

@ahoeben and @FormerLurker, I have run the code through the terminal, as suggested, but I don't see any output file.

I had to modify the code slightly (added a "\" to remove space in the file path and I added an output file path):

/Users/iMac2011/Library/Application\ Support/cura/4.8/plugins/ArcWelderPlugin/ArcWelderPlugin/bin/osx/ArcWelder --log-level=DEBUG -m=1000000 -t=0.01 -r=0.05 -s=1.0 -a=12 /Users/iMac2011/Google\ Drive/3D\ printing\ stuff/Test\ Prints/ArcWelder-Snake.gcode /Users/iMac2011/Google\ Drive/3D\ printing\ stuff/Test\ Prints/AW-ArcWelder-Snake.gcode

 

The code seem to run without problem but the output was not generated. The terminal output is this:

The terminal did not display any debug info (maybe "segmentation fault"?) and I couldn't find the log file. If it exists, where do I find it? I looked near the ArcWelder plugin location.

[ahoeben 1,808]

I have created a new development snapshot which includes an OS X executable of the ArcWelder console application that I manually built on an OS X 10.12 virtual machine and which seems to work there.
