BCN3DSigma-ProGen

Profile Generator for Simplify3D, Cura & Cura 2 slicing softwares. Specifically designed for the BCN3D Sigma.

The official code behind the Sigma ProGen web interface. It generates profiles according to hotends, filaments and qualities defined in resources folder.

Requirements

  • Python 2.7 installed.
  • resources folder with at least one hotend in hotends folder, one filament in filaments and one quality preset in quality. The included one comes with all hotends, filaments and qualities we have tested.

Usage

Clone/download the repository in your computer:

git clone https://github.com/BCN3D/BCN3DSigma-Profile-Generator

Decompress it if you need to, open a terminal, go to the directory and call the script:

python progen.py

Will ask for a functionality:

  1. Profile for Simplify3D: Will ask for left Hotend, left loaded Filament, right Hotend and right loaded Filament. Then will generate the fff profile file.

  2. Profile for Cura: Same as 1, now for Cura (will ask for Quality at the end).

  3. Profile for Cura 2 [Beta]: Asks nothig. Generates all the files to add the Sigma to Cura 2 and, if Cura 2 is already installed, copies all the files to the right places.

  4. Experimental features: Some experimental extra features.

  5. Exit: Quit the program.

In order to add, remove or change a hotend, filament or quality preconfiguration edit the files in Profiles Data folder.

Fast mode (No GUI)

To generate a profile without entering the GUI.

Simplify3D: call the script and insert 4 valid parameters:

python progen.py LHotend RHotend LFilament RFilament --software

Cura: call the script and insert 5 valid parameters:

python progen.py LHotend RHotend LFilament RFilament Quality --software

Cura 2: Still not available.

Valid parameters for Hotends are filenames in /resources/hotends or 'None' if not mounted. Valid parameters for Fiaments are filenames in /resources/filaments or 'None' if empty. Valid parameters for Quality are filenames in /resources/quality. Examples:

python progen.py "0.4 - Brass" "0.4 - Brass" "Colorfila PLA" "Colorfila PLA" --simplify3d

Generates the file BCN3D Sigma - 0.4 Left (PLA Colorfila), 0.4 Right (PLA Colorfila).fff

python progen.py "0.4 - Brass" "0.4 - Brass" "Colorfila PLA" "Colorfila PLA" "Standard" --cura

Generates the file BCN3D Sigma - 0.4 Left (PLA Colorfila), 0.4 Right (PLA Colorfila) - Standard.ini
