Simplify3D and OctoPrint


I’ve just purchased a license for S3D and I’m starting to learn it/configure it for my Velleman k8200 printer. I’ve been running Slic3r previously and that slicing tool has a great integration to OctoPrint and I’ve not found anyone that has proposed a simple way to send the gcode output from S3D to OctoPrint so I’ve solved it fairly easily by simply issuing a curl command.

Go to Edit Process Settings and select the Scripts tab and enter the following statement

curl -H "X-Api-Key: 185A556C8F684E20AAB85F2D867F2791" -F "select=false" -F "print=false" -F "file=@[output_filepath]" ""
  • Change to your own API-key
  • Modify the URL (and if you want to save it to your sdcard change the URL to …/api/files/sdcard)
  • If you want the uploaded file to become selected upon upload change select=false to select=true
  • If you want it to start printing upon upload change print=false to print=true
