      Super cool. Is there a way via parameters I can tell it which printer to upload to? Maybe I should just open the project 😃

          Yeah, you set the hostname in Preferences 🙂

              Once we start using firmware 1.19 and get FTP support again, perhaps scripting Transmit or something similar will be a better idea than using a dedicated app for uploading.

                Bear in mind that direct wifi printing comes with security implications. What facilities does S3D provide for authenticating access to the printer over WiFi?

                  I like the idea of some sort of file transfer script to the duet as a S3D post process, mainly to reduce the steps required…

                  I've come from smoothieboard, which at the time had problems with S3D.. so I'm used to annoying steps in the process, the smoothie/s3d issues is now comipletely fixed by the way, but what I used to have to do was:

                  • Slice in S3D, save to temp folder

                  • alt-tab to web site for S3D move cleanup process

                  • upload gcode file from temp folder

                  • Save processed file back to temp folder

                  • alt-tab to octoprint page

                  • upload gcode file from temp folder

                  • Hit print & watch

                  So I'm pretty used to multiple steps. but its better now, with my DUET my process is:

                  • Slice in S3D, save to temp folder

                  • alt-tab to DWC page

                  • upload gcode file from temp folder

                  • Hit print & watch

                  If I could have a S3D post process script that saved the file directly to the DUET, probably via FTP I assume would be easiest.. then it would save having to have a temp folder and the upload step.. it would end up:..

                  • Slice in S3D, (Post process script saves directly to DUET.. with option on what folder it saves to? )

                  • alt-tab to DWC page

                  • Hit print & watch

                    DC42… I have in mind more like the Octo/Repetier method. HTTP upload and control. There is an API key generated to keep it secure

                          I believe it can be done with the same manner. Will try when I get home.

                            Upvote. I put a feature request on the Slic3r Github to have a more generic 'send to printer' option like a command line, but emulating OctoPrint to receive gcode for printing might be a faster way to fitting in with more existing systems.

                                I am using windows, so not sure if this works for Mac or not.
                                You will need to download curl and have it in your system path
                                then put these in Post Processing > Additional terminal commands for post processing (Replace the IP with your Duet IP)

                                [c]curl –data-binary "@[output_filepath]" -X POST http://192.168.1.###/rr_upload?name=gcodes[output_filename].gcode
                                curl -G http://192.168.1.###/rr_gcode –data-urlencode "gcode=M32 [output_filename].gcode"[/c]

                                The file will be uploaded and printed upon saving the g-code
                                If you want to disable it, add 'rem' before each of the line to skip them

                                edit: use M32 instead of M23 M24

                                  It's probably easier to use [c]M32[/c] instead of [c]M23[/c] + [c]M24[/c].

                                      You are my hero! Works perfectly. I need to work on my upload speed or at least get it to do the upload in the background. a 30MB files takes a couple minutes to upload.

                                        The file will be uploaded and printed upon saving the g-code

                                        Note that this will only work if you have previously connected to DWC via your browser first. If you didn't connect to DWC since the last reset of your Duet, the first call to curl will silently fail with HTTP error 500, and the second one will start printing the old version of your gcode file if one was already there. If not, then nothing will happen.

                                        So there is no perfect solution yet… I wish we had an API key like octoprint so uploads would be secure and accepted with a single curl command.

                                        Cheers,
                                        Ben.

                                        EDIT: You can mitigate this somewhat by issuing an M30 beforehand to delete the existing file on the Duet, so if the upload fails then it won't try to print an outdated file. So the full block becomes:

                                        [c]curl -G http://192.168.1.###/rr_gcode –data-urlencode "gcode=M30 [output_filename].gcode"
                                        curl –data-binary "@[output_filepath]" -X POST http://192.168.1.###/rr_upload?name=gcodes[output_filename].gcode
                                        curl -G http://192.168.1.###/rr_gcode –data-urlencode "gcode=M32 [output_filename].gcode"
                                        [/c]

                                          Is there a way for it to work on files with spaces in them? I know the easy answer is to save without spaces, but sometimes I forget 😃

                                          Good call on the delete statement first!
