yorikvanhavre commented on 29 Dec 2014 I'm not sure how this should be done? Isn't it better to have a special pre_ script that maps all A values to Y? |

sliptonic commented on 29 Dec 2014 No, that would undo what we're trying to do. Gcoderipper is easy to install and can be downloaded here: http://www.scorchworks.com/ It's the program running in the middle of the image above. It has a number of interesting features for working with paths. In this case, it's taking a 2D path in XYZ and mapping the Y axis moves onto A axis with a given diameter. This effectively 'wraps' the engraving around the cylinder. However, if I import that path into FreeCAD, it doesn't look like the wrapped cylinder since no A moves are shown. Somehow, GcodeRipper addresses this with the ISO views. |

yorikvanhavre commented on 29 Dec 2014 I can't make the g-code ripper program display the same thing as in your screenshot with the file linked above... It keeps telling me "Aborting G-Code Reading: A Codes are not supported". Is there any other option to configure? Anyway it is still not clear to me what we need to achieve, if it is not mapping the A values to X or Y? |

yorikvanhavre commented on 11 Apr 2015 This is not that easy... It really involves building a complex, new display mode to show/map the paths on a cylinder... I suggest we leave that for after the merge |
