      Thanks for that as a start… Should be able look at it soon.... I read a thread here that slic3r supported duet again but that is maybe not in the PE branch. If I get the Perl script to work I'll post it....

        Slic3r has it, Slic3rPE does not (yet?).
        What are the main differences between the two anyway? Apart from PE being developed towards the Prusa machines.

          I doubt that this feature will be integrated into the prusa edition - the main audience of the software are users of prusa printers, which don't use Duet boards. 😕

            the PE version has a lot of improvements and has a higher development rate…so I would like to stick with that...but as said the perl script is an option i will investigate

              I thought so aswell, but Slic3r is actually updated regularly. Last update is from 26th feb.

                OK I found a solution. It is a bit of a hack where I use the ip address /url to determine whether to send it to an octopi or a duet
                my octopi has address octopi.local
                my duet has address hevo.local
                I needed to do this since the PE version doesn't have the member variables that the orginal slic3r has compiled in c++. And there is no host_type as in the code above. And I have no urge to compile it all ..
                it is a hack an I will need to change it for every new releae..however I'm so use with my octopi just to hit 'send to printer', that it is worth it for me.
                for windows you will need to change the file (1.39 as example)

                  I wonder if it would be possible to just do a pull request for Slic3r PE to take the Duet connectivity from the main Slic3r dev branch that already has it working.

                    It seems prusa hasn't merged that code from slic3r. I checked the source code of 1.39 and didn't find the changes in PE

                          It looks like it is this commit https://github.com/alexrj/Slic3r/commit/1c74067da09a9a23ce66227b55146af6182d747d, it should be possible to pull it in and build your 'own' slic3r version, but I guess that these are not the only changes needed. 5fbb245b9790193b6924735fd985dc3cd2350ee6 and 13f121e3d952cca33b1ee5fdd73c12d85bf54d0e also mention the duet.

                          Edit: As I said before, I doubt that this would get accepted 😕

                            Nice work, well done. (in lieu of a 'like' button for an individual post) 🙂

                              I don't think prusa will accept a pull request for this issue at the moment.
                              On github i found the following open issue https://github.com/prusa3d/Slic3r/issues/695, seems they will do some refactoring.

                              Today they committed a change which seems to be part of the refactoring.

                                We'll see if we get a response to the most recently opened issue on Github https://github.com/prusa3d/Slic3r/issues/935. I'm not too hopeful that the Prusa version will ever add in support for the Duet. I ended up making a post processing script that uploads the gcode file. The script is basically just the perl code that slic3r usually uses to upload files.

                                #!/usr/bin/perl -i
                                
                                use strict;
                                use warnings;
                                use LWP::UserAgent;
                                use File::Slurp;
                                use File::Basename;
                                
                                # Set up filepath and filename
                                my $filepath = $ARGV[0];
                                $filepath =~ tr|\\|/|;
                                my $filename = basename($filepath);
                                
                                my $ua = LWP::UserAgent->new;
                                my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
                                my $t = sprintf("%4d-%02d-%02dT%02d:%02d:%02d",$year+1900,$mon+1,$mday,$hour,$min,$sec);
                                
                                my $server_endpoint = "http://192.168.X.XX/rr_upload?name=gcodes/$filename&time=$t";
                                my $req = HTTP::Request->new(POST => $server_endpoint);
                                my $data_file = read_file( $filepath, { binmode => ':raw' } );
                                $req->content($data_file);
                                 
                                my $resp = $ua->request($req);
                                
                                if ($resp->is_success) { 
                                    my $message = $resp->decoded_content;
                                    print "Received reply: $message\n";
                                }else {  
                                    print "HTTP POST error code: ", $resp->code, "\n";
                                    print "HTTP POST error message: ", $resp->message, "\n";   
                                }
                                

                                You'll have to put the address of your Duet where the "XXX" are in the $server_endpoint var. I run all my post processing scripts from a windows bat file which looks sort of like this at the end:

                                pause
                                perl "C:\Program Files\Slic3r\uploadgcodefile.pl" %1
                                del /f %1 
                                pause
                                

                                The bat file uploads the gcode file and then deletes it. The first pause allows me to close the command window to cancel the upload/delete command. The last pause allows me to verify the upload worked.

                                This process definitely isn't perfect, but is easier than manually uploading files.

                                  Hi,

                                  I've added the option for sending G-Codes to Duet and already created a pull request for it (https://github.com/prusa3d/Slic3r/pull/1051)
                                  Let's see if Prusa will overtake it into their repo.

                                  If someone is interested in testing it can be cloned from https://github.com/mloidl/Slic3r/tree/duet

                                  Best regards,
                                  Martin

                                        @mloidl thanks for the work! great to see it was accepted!

                                        If it's not too much trouble, do you think you could post a release already built with the commit?

                                          @mordekain I have not yet tried to build a release for another pc than mine. I'll try to create a linux appimage for testing. I'm not able to provide a windows or mac executable.
                                          On the other hand i assume prusa will release another beta or release candiate soon (current beta was released 19 days ago)
