DXF Plotter

Fast and easy to use DXF to GCode converter for laser and router CNC

This application helps users converting DXF files to GCode with minimal settings, fully configurable GCode commands format and fast spline to arc conversion.

It targets only laser and router CNC following every lines and arcs from DXF file with optional desired depth.

⚙ Features

• DXF support of line, arc, circle, polyline, spline
• Customizable GCode command format
• Saving current work to file
• Multi selected path setting edition
• Path offseting (Tool Compensation)
• Pocket generation with islands capabilities
• Multi passes with depth
• Scale and translate paths
• 3D path simulation of the file

Execution

Linux and Windows systems are supported.

Running from exe (Windows)

Download latest , extract it and run dxfplotter.exe

Running from AppImage (Linux)

Download latest and run:

chmod +x dxfplotter-*.AppImage
./dxfplotter-*.AppImage

🏗 Manual installation from source (Linux)

This project depends on Qt5, for debian like distribution following command install all dependencies:

sudo apt-get install qtbase5-dev

git submodule init
git submodule update

cmake -B build
cmake --build build -j $(nproc)

Usage example

Launch GUI

build$ ./dxfplotter

With a specified dxf file

build$ ./dxfplotter input.dxf

With a specified file and tool

build$ ./dxfplotter input.dxf -t "Mill 1mm"

Once opened, select path from left panel or from viewport and modify settings of selected path group or of single selected path.

Export with File->Export or Ctrl+E

✏ Configuration

Configuration settings are exposed in Configuration->Settings, the configuration is splitted in two:

• general settings aiming dxf importing or default values
• tools with settings such as radius and gcode formatting

📝 GCode format

Simple set of GCode command is used per tool:

Description	Default Command	Available Variables
Pre Cut	M4 S {S:.3f}	S
Post Cut	M5
Plane Fast Move	G0 X {X:.3f} Y {Y:.3f}	X Y
Plane Linear Move	G1 X {X:.3f} Y {Y:.3f} F {F:.3f}	F X Y
Depth Fast Move	G0 Z {Z:.3f}	Z
Depth Linear Move	G1 Z {Z:.3f}	F Z
CW Arc Move	G2 X {X:.3f} Y {Y:.3f} I {I:.3f} J {J:.3f} F {F:.3f}	F X Y I J
CCW Arc Move	G3 X {X:.3f} Y {Y:.3f} I {I:.3f} J {J:.3f} F {F:.3f}	F X Y I J

They can be customized from tool Settings panel Configuration->Settings->Tools->ToolName->Gcode or from dxfplotter/config.yml file in your applications configuration folder.

Variables provided in formatting are available with {#:nf} where # is one of the supported variables and n the float precision:

Name	Description
S	Laser intensity
F	Movement feedrate
X	Movement X axis target
Y	Movement Y axis target
Z	Movement Z axis target
I	Relative arc center absciss
J	Relative arc center ordinate

Properties S and F are exposed in path settings in UI.

3D simulation view

The following controls help you to navigate into the view:

Keys	Action
Middle click	Rotate around view center
Middle click + Shift	Translate view center
Wheel	Zoom

Ctrl key can be pressed to slow down motion.
