True wifi printing

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

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.

@Jackal:

You mean start printing?
I believe it can be done with the same manner. Will try when I get home.

Looking forward to this!

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].

Thanks for the heads up, I just put in the first one I found on the wiki

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.

[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

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issuing an M30 beforehand to delete the existing file on the Duet, so if the upload fails then it won't try to print an outdated file.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!
