Hey guys just a few thoughts here. I have a high speed cnc machining center (cnc mill) it has 16mm pitch ballscrews and weighs 6ton linuxcnc is awesome and does a great job controlling it. I make plastic injection molds and lots of 3d machining all the time. plus all the little jobs that a

Can you select, copy, and paste the code you see on screen to a text file? I don't know, I didn't try. Martin ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

How about HeeksCAD/CAM? https://sites.google.com/site/heekscad/ https://sites.google.com/site/heekscad/news/linuxversion The only difference between the free and paid version is the free version puts a note at the start of the G-Code it outputs, which can easily be removed with a text editor.

I'm not a professional draftsman.  I was initially intimidated by FreeCAD, as many people naturally are.  I knew when I was glomming parts together using geometric primitives that I wasn't doing *real* CAD, but that inelegant method allowed me to produce simple usable parts.  Some complex parts

In the meantime I've found that freecad treated my diameters as radii, so the posted image is too big by 2x for xy. Its a 50mm diameter pipe, 35mm long, with a 28mm diameter bore. Makes sense, but big dummy at work. :-) That's a lathe job surely? Why are you trying to mill it? Hope you
