CAD FILE TO CNC
DXF to G-code converter online for CNC routers
GcodAi helps you convert DXF to G-code for CNC router work: upload your CAD file, set the bit, depth, feed rate and spindle speed, and check the 2D preview before downloading the .nc file.
Prepare your DXF file before converting
Your DXF should be clean 2D geometry with no hidden layers or unnecessary duplicate lines. For lettering, convert the text to outlines first, and check that the units are millimeters so the size comes out exactly right.
Close your paths
Contour work should use closed paths so the software can clearly read the part boundary.
Check the scale
Verify the real size in mm so the file doesn't come out larger or smaller than the actual job.
What DXF to G-code is good for
Acrylic signs
MDF woodwork
2D patterns
Line work from CAD
Profile cutting parts
Batch production of repeat parts
