two CAM-like plugins, and other stuff
 
|
Hallo people,
i am new on this list. Since 10 years i worked with qcad. Some days ago i tried librecad, and now it is my working platform. By profession i'm a CNC programmer for milling machines. The "list entities" -plugin give me the idea of writing my own plugins, usable like a simple CAM. The first experiment write lines for milling contours, and the second creates bore hole patterns. See https://github.com/DietmarK/librecad for more details. The code is not professional, but it works for me. The generated CNC-code is for Heidenhain-NC. It can be modified for other NC's, such as G-code. For a better work with librecad i added some modifications to the code, see readme-librecad-modified-sources. Try it out! I hope it is helpful.

Dietmar,
that's pretty cool! I started my own CAM plugins for profiling and pocketing, but didn't had time to finnish that myself. There is some new light though since a Libreary is in development that allows for doing that. note to myself, may be it's a good idea to start a LibreCAD plugins project where people can submit code? And may be a way for plugin naming… just some random thoughts. Ries On Jan 20, 2012, at 2:16 PM, DietmarKuehn [via LibreCAD] wrote: Hallo people, |

Hi Dietmar,
Just one comment: It seems that you have being modifying the rs_grid part, where improvement is needed, as shown here: http://sourceforge.net/tracker/index.php?func=detail&aid=3437105&group_id=342582&atid=1433847 Thanks, Dongxu On Fri, Jan 20, 2012 at 2:16 PM, DietmarKuehn [via LibreCAD] <[hidden email]> wrote: Hallo people, -- Dongxu Li, Ph.D. |

Hello Dietmar,
Yours changes in doc_plugin_interface.cpp and plugins/document_interface.h are Ok Only one thing, I changed the line 102 for: REVERSED=291 /*!< bool: true if arc is reversed (clockwise) */ to maintain the "dxf like" and I send a pull request and these lines are part of master source |

Hallo Ries,
i am happy about Your response. But I am not suitable for leading a project, i am a absolute beginner in programming with QT. It was a big work for me to create an account on github today, it takes many hours. Some years ago i wrote something in C (an simulation for CNC-milling programs) and in PHP, but with C++ i'm not so familiar. You can see it in my code. But i am disposed to collaborate in such a projekt. Excuse my bad english, i have forgotten most of them in last 40 years. An other thing: it would make me happy, if someone could add some of my suggestions in the main code. It would release me from changing the code manually after every git clone.

Hallo Dongxu,
i modified the grid spacing from 1-10-100-1000 to 1-2-5-10-20-50 . This behavior should be switchable in the settings menu, for users that dont like it. I need it for creating start and end-points for milling contours and so one. It should go automatically, depending on zoom, not by user settings. please look at my code pieces and try it out.

Dietmar,
I was actually thinking of having some for of a plugin structure within LibreCAD on github where people can send and merge there code. This way, when persons clone LibreCAD they will automatically get all available plugins everybody wrote…. random thoughts :) Ries On Jan 20, 2012, at 3:06 PM, DietmarKuehn [via LibreCAD] wrote: Hallo Ries, |

hallo Rallaz,
thank you. i have another question: how can i report a bug, when i found it in newest github-version? I have never maked a bug report. Pease help me. Dietmar Am 20.01.2012 21:04, schrieb Rallaz [via LibreCAD]: Hello Dietmar, |

Ries,
it's a good idea. But i think, somebody has to overwork my code, i'm not a professional.

Don't feel like you can not contribute because you are not a professional, I think very few who contribute are professional coders but knowledgeable users like you! Here's where you can submit bugs and feature requests: http://sourceforge.net/tracker/?group_id=342582 |

Here's some recent progress with my openvoronoi-project. It can now
take points and line-segments (simple polygons with islands) as input. It can produce an approximate medial-axis (for v-carving), as well as interior and exterior offsets. http://www.anderswallin.net/2012/01/emc2-filters/ this is under very active development so things crash easily and APIs can and will change abruptly without notice. I can help if someone wants to write a plugin to librecad for this, but it's unlikely I can do this on my own (unless you provide very easy examples+tutorials!) Anders |

High priority for me now are moving the blog and translation server over to the LibreCAD server and create the wiki system for LibreCAD. please…stay tuned :) Ries

Hi guys,
I am interesting in can do a software cam based in LibreCAD. I have a cnc Laser run under LinuxCNC. Is posible to adapt LibreCAD to generate G-Code of cutting and engraver for LinuxCNC? Thanks |

Through the plugin interface some basic CAM functionalities and G-Code generation should be perfectly possible. On Jul 18, 2012, at 10:29 AM, diegoroman17_2 [via LibreCAD] wrote: Hi guys, |

How I can use this plugin?I control the power laser with velocity spidle commands. Is it posible with the plugin?

Ries,
Do you have any code for the CAM work that you have done? I am currently looking at how to impliment such a plugin and i would like to see / use anything you have so far. Thanks, Dubstar_04 |

Hey,
I did some initial work overhere : https://github.com/LibreCAM/LibreCAM The current status is that some dialogs are working, but non of the CAM functions are implemented. However, it does give you an idea how plugins in LibreCAD works. Ries On Dec 6, 2012, at 7:58 AM, Dubstar_04 [via LibreCAD] wrote: Ries, |

Take a look at the gallery: https://picasaweb.google.com/106188605401091280402/OpenVoronoiExamples There's been some interest in using openvoronoi from dxf2gcode ( a simple 2D/2.5D g-code generator), freecad (a 3D parametric CAD modeler), slic3r (a 3d-printer g-code generator), pycam, and so on. I hope to improve openvoronoi (there are corner-cases that cause crashes), and support some of these GUIs/Applications eventually. If there's someone who is familiar with the LibreCAD geometry data representation and with the cam-plugin and GUI APIs then I can help with the openvoronoi integration. Note that openvoronoi requires an input format similar to PSLG described here: https://www.cs.cmu.edu/~quake/triangle.defs.html Anders |

Hi Anders,
I have been looking at your library with the intention of using it in a CAM plugin. I use HeeksCAD (CNC mill) and Slic3r (reprap) at the moment but i would like to use LibreCAD more for my CNC work. I have only started looking at LibreCAD this week but i should be able to get a plugin GUI and CAM framework drafted up in the next few weeks. I would really like it if you could help me use your library in LibreCAD and get a working cam plugin. Once i have the GUI close and the CAM framework drafted together i will post here and hopefully we can move forward together. Do you have any documentation i could look at in the meantime? Examples using openvoronoi with C++ would be great. Thanks, Dubstar_04 |

So is there a functional CAM plugin for LibreCAD?
