PrusSlicer never finishes upload with PI4

[Stephen6309]

On my Duet 3 6HC+1LC+PI4 3.4.0rc1, same with proir versions, PrusaSlicer never finishes the upload using any of the upload options. The file does fully upload, but the process in the slicer never finishes. So, I have to cancel the upload to do anything else. PrusaSlicer versions: 3.4.0, and 3.4.1beta1, and SuperSlicer 2.4.58.0. PI4 powered by a Meanwell power supply.

In standalone mode, it works fine.

Deleting the printer and adding it again doesn't fix it. It been occuring for a while now. The test button finds the printer just fine.

Must be something on my pc, since I don't find on their github any issues reported for this. It really hasn't bothered me much, since it kinda worked.

[PetrKroupa]

@stephen6309 - Same in my setup. Two printers. 6HC+1LC + SBC pi4.

[bot]

PrusaSlicer handles the functions differently for DSF vs "RRF." I do not have an SBC to test. What is the way to do things with SBC vs standalone?

[chrishamm]

@stephen6309 @PetrKroupa I just tried this with PrusaSlicer 2.4.0 and the print started right after the upload. If you have SSH access to your machines, can you run

journalctl -u duetwebserver -f

and check what happens when you send a G-code job to your printer?

[PetrKroupa]

@chrishamm -

Run comand and start upload.

If I can test something else, let me know.

[chrishamm]

@petrkroupa I cannot spot anything obvious there, it seems PS is getting stuck at some point during the transfer. I cannot reproduce this problem either, I just tried to upload a 20MB file and it worked as expected. Are you using Windows?

@bot It's just a PUT request (e.g. PUT http://duet3/machine/file/gcodes/myFile.gcode) with the plain G-code file as the body content. I just noticed one potential problem in PrusaSlicer 2.4.0: When you upload a file to a subdirectory, it doesn't use a slash but a backslash in the upload request as the directory separator (at least on Windows). Can you confirm this?

[bot]

@chrishamm I was just taking a look to see what might be going wrong. You could be correct. It encodes the filename directly to the url.

	if (connectionType == ConnectionType::dsf) {
		return (boost::format("%1%machine/file/gcodes/%2%")
				% get_base_url()
				% Http::url_encode(filename)).str();

Which is called like this (filename is the first argument):

auto upload_cmd = get_upload_url(upload_data.upload_path.string(), connectionType);

Which, digging into it, seems to directly set the upload path as the filesystem directory. So, yeah, on WIndows it might have \ instead of /.

In the logs above, I did notice:

Feb 16 16:57:23 malej DuetWebServer[596]: DuetWebServer.Controllers.MachineController[0] [UploadFile Failed upload file gcodes/fixa_cidlo_0.2mm_PETG_malej_12h39m.gcode (resolved to /opt/dsf/sd/gcodes/fixa_cidlo_0.2mm_PETG_malej_12h39m.gcode) Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException: Unexpected end of request content.    at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.Http1ContentLengthMessageBody.ReadAsyncInternal(CancellationToken cancellationToken)    at System.Runtime.CompilerServices.PoolingAsyncValueTaskMethodBuilder`1.StateMachineBox`1.System.Threading.Tasks.Sources.IValueTaskSource<TResult>.GetResult(Int16 token)    at System.IO.Pipelines.PipeReader.CopyToAsyncCore[TStream](TStream destination, Func`4 writeAsync, CancellationToken cancellationToken)    at DuetWebServer.Controllers.MachineController.UploadFile(String filename, ISessionStorage sessionStorage) in /home/christian/Duet3D/DuetSoftwareFramework/src/DuetWebServer/Controllers/MachineController.cs:line 410

But I do not understand what it means exactly.

[chrishamm]

@bot Thanks for looking into it. Unexpected end of request content means the request was too short which can be expected when the HTTP request is cancelled. So nothing unusual in there AFAICS.

[bot]

@chrishamm

I think the filename argument ends up being different depending on where the upload is initiated from. There seeems to be a background process that will upload files at times, or prepare the data for upload at least.

@Stephen6309 Do you have background slicing/processing enabled in prusaslicer? I forget what the exact feature name is called. It's in the app preferences.

Anyways. It seems to me that the path is set by the user input of the upload dialog.

Plater.cpp Line 6310

    PrintHostSendDialog dlg(default_output_file, upload_job.printhost->get_post_upload_actions(), groups);
    if (dlg.ShowModal() == wxID_OK) {
        upload_job.upload_data.upload_path = dlg.filename();
        upload_job.upload_data.post_action = dlg.post_action();
        upload_job.upload_data.group       = dlg.group();

        p->export_gcode(fs::path(), false, std::move(upload_job));
    }
}

There is a note on the dialog to use forward slashes a directory separators.

[PetrKroupa]

@chrishamm - Yes, on windows. Today I discovered an interesting thing. I use the arc welder plugin in post-processing scripts. If I do not use it, the upload will go smoothly.

@Stephen6309 - Do you use ARC Welder too?

[chrishamm]

@petrkroupa That's the reason why it doesn't work. Perhaps PrusaSlicer doesn't wait for ArcWelder to finish or it attempts to use file information of the old unprocessed file before it sends it over to the Duet.

Either way this is no problem in DSF or RRF.

[PetrKroupa]

@chrishamm - I agree. I assume that @Stephen6309 will confirm that he also uses this plugin. That's probably why no one has solved it yet and had no problem with it. This combination is probably not very common.

Thanks for help.

[Stephen6309]

@petrkroupa Yes I use arcwelder. But this problem only occurs with the PI4.

[PetrKroupa]

@stephen6309 - I can't test that because both printers I have with RPi4. However, if without SBC it works ok then it will be something in DSF or RRF. What do you think @chrishamm ?

[chrishamm]

@petrkroupa I am not convinced this is a problem in DSF. If you can upload files as usual using the web interface and if it works from PrusaSlicer without ArcWelder, it's obvious that ArcWelder interferes somehow with the upload process.

[Stephen6309]

@chrishamm Upload fine in standalone mode using arcwelder. My Duet 3 Mini 5+ is in standalone mode and everything uploaded fine. When I had a problem on my 6HC, I set it up in standalone mode for troubleshooting and the uploads worked fine.

The only difference between the two, is the PI4.

[Stephen6309]

@chrishamm PrusaSlicer 2.4.1beta4, SBC mode never finshes upload.

[chrishamm]

@stephen6309 I cannot confirm that (this is without ArcWelder on Windows x64):

I just checked 2.4.1-b3 on Linux x64 and there it works with ArcWelder too.

[PetrKroupa]

@chrishamm Without an arc welder, it works on both my printers. Both 6HC + SBC. But not with ARCwelder. It always gets stuck at 96-97% depending on the file size.
I don't have a Linux PC to test it.

[Stephen6309]

@chrishamm Without arcwelder or the PI, it works fine. Just not working in SBC mode.
