Convert STL to DXF?

Mostly Printed CNC - MPCNC Advice
1

Anyone have any tricks for converting an STL to a DXF?

Modeled something in Fusion, but everything is flat parts that I can cut with the MPCNC. Since some of the parts are cloned objects with small edits, or extruded cuts through multiple objects, I can’t use the sketches for everything.

It is some manual work but this is how I would do it using a different program. I use Onshape.com but the concept is the same.

 

 

Update: I should add. The “Sketch” he makes first is the same thing as a DXF file.

I use this site to convert STLs to DXF

You may have to register to use it but it works well.

OpenScad, free and lightweight.

Example code, just copypaste between lines:

projection(cut=false)
{
import(“C:/Users/jk/Desktop/vehkeita/Garmin2.stl”);
}

After rendering (f6) choose “Export” from “File” menu and then “Export as DXF…” for system dialogue for save file.

Tinkercad will do it too, in the export menu.

Ah! Life happened, forgot I posted this, and must have missed the email.

Thanks for the suggestions, all!

Well done Aaron, Thank you for your input. I have been trying to find a way to get some huge (484mm x 484mm x 25mm) 3d printer parts into cad to be able to cut them on the MPCNC as they continue to warp on the 3d printer. Even breaking the parts down, the outsides are warping even on Blue tape. I have the blue tape down so well, it actually lifted my magnetic plate up. PETG - Maybe I must move it from the garage where there is less draught.

Any way, I imported the part into Tinkercad and exported as SVG which Qcad has no problem opening. I then use the imported shapes to make into circles etc for Etlcam.

I hope this helps others out.
