Great, that seems to work. Thanks

You're welcome. That's what's a forum for

@MoS-tekknix:

@sungod3k:

I ran the original and the autouploaded file through notepad++s compare tool and they matched 100%

Uhm, thats interesting.

Can you try this one, i'm using and change the IP to your DuetWifi/Ethernet IP?

[[language]]
curl -F "file=@[output_filepath]" "http://192.168.178.144/rr_upload?name=gcodes/[output_filename].gcode"

That is working even if the Printer is currently busy.

This script
curl -F "file=@[output_filepath]" "http://192.168.x.x/rr_upload?name=gcodes/[output_filename].gcode"
uploads the file correctly, but the print doesn't start…

Am I missing something?

[dc42]

You need to send a separate command to print the file.

[tychop]

Yes, I figured that could be the issue, however, I couldn't find anything here https://github.com/chrishamm/DuetWebControl…

Is there a command to print? Where can I look for it?

I can see

[[language]]
function startUpload(type, files, fromCallback) {

```in the javascript, but am clueless how to specify 'print' as the type to upload gcode & start the print

[dc42]

Use the rr_gcode command to send M32 "filename.gcode".

[tychop]

Yep, Got it

This works:
curl -F "file=@[output_filepath]" "http://192.168.x.x/rr_upload?name=0%3A%2Fgcodes%2F[output_filename].gcode"
curl "http://192.168.x.x/rr_gcode?gcode=M32 0%3A%2Fgcodes%2F[output_filename].gcode"

Many thanks !!

[dc42]

You will need to enclose the filename in double quotes when sending it if you want it to work on filenames with ( or ) or ; in the name.

Hi all:

curl –data-binary "@[output_filepath]" "http://192.168.x.x/rr_upload?name=gcodes/[output_filename].gcode"

–data-binary don't losse the NewLine or CarriageReturns as -d do.
and don't add extra data to the gcode file as -F do.

Regards.

The best that worked for me is:

curl --data-binary "@[output_filepath]" "http://192.168..XX.XX/rr_upload?name=gcodes%2F[output_filename].gcode"

curl "http://192.168.XX.XX/rr_gcode?gcode=M32 [output_filename].gcode"

But there are still some problems...

1. If you have a Space in the name, the file is only saved as the first part til the space (e.g. Test file.gcode is saved as Test.gcode)
2. Special Characters (e.g. äöü) aren't saved properly
3. Is there a possibility to delete the file on the local computer after uploading it to the duet? Couldn't find any solution...

greetings kuhni

@dc42

hmm, i guess this is a stupid question, but I am unclear

1. where to put these lovely scripts to load the file.

Content-Disposition: form-data; name="file"; filename="curl_test.gcode"
Content-Type: application/octet-stream

@dc42
I'm currently implementing the G-Code upload for Slic3rPE and struggeling with the same problem mentioned by @BrianHanifin .
Some parts of the HTTP-Header are saved in the G-Code after upload when uploading the G-Code using form_add of libcurl.
Is it somehow possible to support forms in the firmware?

Thanks,
Best regards

HI,

I have just installed a Duet Wifi and running well...However, I cant work out how to get the slicer to control bed temp. Simplify3D wants tools and laser to be indicated as T0 to T5, and Duet indicates bed as 'B' .... Yes, I can and do control bed temp manually prior to printing, but I want it auto controlled by g-code.

Could the gurus here help please ?

Thanks

[OBELIKS]

I think you are overthinking it. Do you have multiple beds?
If not, default setting in S3D is OK, it will output M140 S70 to set bed temperature to 70°C, and that works with Duet

In case anyone's interested... here's how I print from Linux...

#!/usr/bin/env bash
echo "$(date) $@" >> /var/log/pp.log
printit() {
   set +xe
   op="$1"
   of=$(basename "$op")
   ncftpput -t 5 duet0 /gcodes/ "$op" || ncftpput -t 5 -v duet0 /gcodes/ "$op"
#  I do the ncftpput again if the first one fails as it does sometimes.
   fn=$(python -c "import urllib ; print(urllib.urlencode({'gcode': 'M32 \"$of\"'}))")
   echo $fn
   curl "http://duet0/rr_gcode?$fn"
   echo "Done"
}

printit "$@" 2>&1 >> /var/log/pp.log

save that someplace and make it executable. You do need ncftpput (part of ncftp package), curl and python (both of which are standard). There are no issues with spaces in the filename BTW.

In Simplify3D Process, Scripts, Post Processing put something like...

/bin/bash /data1/3d/duet/pp.sh "[output_filepath]"

substituting "/data1/3d/duet/pp.sh" with wherever you put the script.
All you have to do now is 'Save Toolpaths To Disk" and the file should transfer and start printing after the save is complete.

I have also had good luck printing directly from Simplify3D.
Like others have said, you need to set "M555 P2" at the end of your config.g to turn on Marlin emulation and you also have to set "Hardware Flow Control" in the firmware Communications settings.

If I didn't have the PanelDue 7i, I'd print directly. I'm not overly fond of having to switch desktop windows around to start the print.

I've cobbled up a quick powershell script for the purpose when I got my Duet. It watches a folder for new/changed .gcode files and offers to upload them.

# adjust these to your values
$folder = "e:\3dprint\gcodes"
$filter = "*.gcode"
$Global:baseUri = "http://duet3d.local/rr_upload?name=gcodes/"

	
Add-Type -AssemblyName PresentationCore,PresentationFramework
$Global:lastPath = ''
$Global:lastTime = Get-Date

$Watcher = New-Object IO.FileSystemWatcher $folder, $filter -Property @{ 
    IncludeSubdirectories = $false
    NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'
}

$changeAction = [scriptblock]::Create('
    $path = $Event.SourceEventArgs.FullPath
    $name = $Event.SourceEventArgs.Name
    $timeGenerated = $Event.TimeGenerated

    # usually multile change events are triggered when a file is written, no need to spam those
    if ($Global:lastPath -ne $path -or ($Global:lastTime - $timeGenerated).TotalSeconds -lt -10) {

        $Global:lastPath = $path;
        $Global:lastTime = $timeGenerated
        $msgBoxResult =  [System.Windows.MessageBox]::Show(("Upload `"{0}`" to the printer?" -f $Event.SourceEventArgs.Name),"GCode Upload","YesNo","Question")

        switch  ($msgBoxResult) {
            "Yes" {
                try {
                    Invoke-WebRequest -Uri ("{0}{1}" -f $baseUri, $name) -Method Post -InFile $path 
                } catch {
                }
            }
            "No" {
            }
        }
        }
')

$onChanged = Register-ObjectEvent $Watcher Changed -SourceIdentifier FileChanged -Action $changeAction

# prevent the console from closing
while (1) {
    sleep 2
}

Save somewhere with .ps1 extension and edit line 2-4 to match your settings. To run it rightclick the file -> "Run with PowerShell" and leave the powershell window open. To trigger the upload question just save your gcode file into the folder you specified in line 2.

For anyone still looking through this thread, the following S3D script will upload the file to your printer (with a timestamp) and tell it to start printing that file much like Slic3r would do:

curl  -F "file=@[output_filepath]" "http://XXX.XXX.XXX.XXX/rr_upload?name=gcodes/[output_filename].gcode&time=YYY"
curl "http://XXX.XXX.XXX.XXX/rr_gcode?gcode=M32[output_filename].gcode"

Copy and paste into "Additional terminal commands for post processing" under the Scripts tab and replace XXX.XXX.XXX.XXX with your printer's IP address or hostname if applicable. As mentioned above, DWC will throw a couple of errors but doesn't seem to impact the print in any way. Happy printing!

[dc42]

You may wish to add the following line at the end:

curl "http://XXX.XXX.XXX.XXX/rr_disconnect"

This will avoid RRF buffering up messages that S3D isn't going to fetch.

I have try pathio alpha/beta versions and have Duet integration, to upload files, and they do not add any header to gcode file uploaded.

[mwolter]

Worked on this for a while and was able to resolve the issue where file names are truncated if the name contains a space.

Basically all it does is replace spaces in the file name with %20, a simple form of URL Encode. It also uses --data-binary and does not add any extra text to the Gcode like the -F option does. Paste this into the 'Additional terminal commands for post processing' on the Scripts tab of Simplify 3d... don't forget to change the IP address. I'm sure there's a more elegant way but this works on a Mac.

bash -c "echo 'http://xxx.xxx.xxx.xxx/rr_upload?name=gcodes/[output_filename].gcode' | sed 's/ /%20/g' | curl --data-binary '@[output_filepath]' $(</dev/stdin)";

Hello, sry for bumping this thread, but just wanted to say thank you for this. Been wanting this 'feature' for awhile now, and just found this thread and got it working! WOOT!

But I do get a error when starting the file. Is there a way to eliminate the error? Thanks!

My script is as follows:
curl -F "file=@[output_filepath]" "http://192.168.0.10/rr_upload?name=gcodes/[output_filename].gcode&time=YYY" ; uploads file to printer
; curl "http://192.168.0.10/rr_gcode?gcode=M32[output_filename].gcode" ; Starts the file printing
curl "http://192.168.0.10/rr_disconnect" ; Not sure what this one does
