G-code generation - PyCAM and OpenSCAM

PyCAM

Install and open PyCAM. Open DXF file.

Remove unused tools, set your tool diameted – 3mm in this case.

Leave only Engraving proces.

Set Max. Step Down = how much material – 0,5mm in this case will be removed in one pass

Engrave Offset = Tool Diameter/2 – 1,5mm in my case because tool was 3mm

Set lower margin for x,y - 5mm

Set upper margin for x,y – size of outside dimentions + 5mm

5mm because cutting tool has 3mm, so 2mm as buffer.

Set Lower Z=-3 – material thikness in my case was 3mm

„Move model” Lower Z=-3 – material thikness

Model Extension – enable supports

Press „To Origin”

Press „Shift”

Press „Generate All”

Press „Export All”
