I use open source FreeCAD for gcode generation. Estlcam is easy to use but not free like FreeCAD. Here is a short step-by-step description of the process of converting line art in InkScape to gcode generated by FreeCAD: 1. In Inkscape, all paths need to be closed, FreeCAD with throw an error otherwise. Also, set the position of the object you wish to mill to 0, 0 before exporting. 2. Export Inkscape drawings to dxf - don’t use svg because FreeCAD doesn’t convert the dimensions correctly. 3. In the FreeCAD draft tool, select all elements in the drawing from the model tab on the left and upgrade them to faces by applying the modification/upgrade menu item twice. 4. Convert the faces to a sketch with the modification/convert to sketch menu item. 5. Switch to the part design tool and select the sketch from the model tree on the left and create a body for the sketch by applying the partdesign/create a body menu item. 6. Switch to the part tool and select the part/extrude menu item. 7. Provide details on the material thickness into the data entry form. 8. Switch to the path tool and create a job from the path/job tool. 9. A form will appear to select the object you just created for to generate the paths. 10. In the job data tabs select one of the available milling tools, such as 1/8 in milling bit. 11. Select the profile operation from the path/profile menu. 12. Enter values for path final depth and step down in the profile parameters depths tab. 1 to 2 mm step down is usually good. 13. If you want to add hold-down tabs select path/path dressup/tag menu. 14. Finally, select path/post process menu to generate the gcode. On Thu, Feb 20, 2025 at 3:41 AM Jake Watters via sudo-discuss < sudo-discuss(a)sudoroom.org&gt; wrote:
