Use Luban for CNC Cutting (vs CNC 3D milling)

Snapmaker Luban

Hello - New to Luban and the forum.

I am looking for the ability to cut vector shapes from flat material using the CNC function. This would be similar to the laser cutting function but with a CNC tip and a kerf definition based on the tool width. This function would be something similar to the program SheetCAM.

The current Luban CNC function assumes a carving function and does a raster scan in 3D space. This creates a rastered line edge and lots of extra cutting time and wasted loose chip material, especially for larger areas.

Before I go check into purchasing SheetCAM, I thought I’d check to see if there is a close approximation in Luban.

Found my own answer. I imported a 3d shape file and so the software assumed a 3D shape. If I import a DXF file, it assumes a 2D shape and offers a vector process that mills the outline.

Hi bhorski, I just got around to trying the same exercise with FreeCAD and Luban on a Debian based setup. Your solution worked a charm, thanks for the info.
