DXF for Laser

DXF for Laser

Mac OS, English

Hobbyist: Ross Korsky
Generates a Kerf (laser cut width) compensated DXF file to produce laser cut parts with dimensions that match your drawings geometry. Optionally generates a DXF with multiple layers as well.

General Usage Instructions

Find this add-in under the SKETCH menu as "Save DXF for Laser Cutting"

If you do not see this add-in under the SKETCH menu click: Scripts and Addins  >>>  Add-ins >>>  Select "DXF4Laser"  >>>  hit "Run"

Set your KERF width in the dialog and pick a plainer face of a body to generate a kerf compensated DXF file for. The higher your Kerf setting the tighter your parts will fit together. Using the 60W epilogue laser I have access to I use 0.20mm kerf for small designs I want to pound together cut from 5mm wood and go down to 0.10mm for larger works I want to be able to dry-fit and disassemble before gluing. 

The right kerf setting to use will vary by your material and laser settings. You can either experiment with various settings or cut a test pattern - e.g. cut 10x 5mm wide rectangles, set them side by side and measure the total width then calculate your kerf. I find it helpful to flip every other tile over as laser cuts always have a little bit of a taper to them and this helps average things out. Example: if your total width was 48.5mm then your ‘perfect fit’ kerf is (50 - 48.5) / 10 = 0.15mm

Additional Information

Known Issues

Non-manifold shapes (ones where cutouts share an edge - e.g. two square cutouts sharing a corner) are not supported.

If the top level componant is not the active componant and you are generating a DXF for a deeply nested, and transformed, componant the generated sketches will not correctly overlay the selected face.

Version History

Version Number Version Description

1.1.2

Negative kerf values should be well behaved again. - At some point the Fusion 360 API has started supporting negative offsets. This broke the use of negative kerf values by resulting in a double negative in most cases.
