Frequently asked questions

Last updated: August 2026

What is LatheDXF?

A free web tool that converts a 2D lathe profile DXF into G-code with zigzag roughing and a finish pass, aimed at single-tool wood lathes and Mach3-compatible controllers.

Is it free?

Yes. No account or subscription is required.

Is my DXF uploaded to your server?

No. Parsing and G-code generation run entirely in your browser. See our privacy policy.

Why does a sample profile appear on first load?

A demo profile (4KULP.dxf) loads automatically so you can see how the tool works. Upload your own DXF to replace it, then click Generate G-code.

Which DXF entities are supported?

LINE, ARC, LWPOLYLINE/POLYLINE (including bulge arcs), CIRCLE, ELLIPSE, and SPLINE profiles are tessellated into the toolpath. Very complex files may need simplification in CAD before import.

Should G-code X be radius or diameter?

Match your Mach3 (or controller) configuration. LatheDXF preview always uses radius internally; the export option only changes the numbers written in the G-code file.

What is “step down” and “finish allowance”?

Step down is how much material is removed per roughing level. Finish allowance is stock left on the profile for the final finishing pass.

Can I edit the G-code?

Yes. Edit text in the G-code panel and click Update preview. Double-click a line to toggle G0/G1 or change F values.

Is the output guaranteed to work on my machine?

No. Always verify, simulate, and test safely. Read our disclaimer and the usage guide.
