You will need an editor if you want to review/edit the code. I personally use VS Code, but the stock “Notepad” is ok too (viewing only). Just be careful with what post processor you use (if any), and like others have recommended, simulate the code before you run it until you get comfortable.

You can use these to simulate the Gcode:

> **[NC Viewer // GCode Viewer and Machine Simulator](https://ncviewer.com/)**
>
> Powerful online GCode Viewer to simulate GCode files. NC Viewer is the best free gcode editor for verifying CNC and 3D printer files.

> **[Browser-based 3D Slicer](https://grid.space/kiri/?ver:3.7.1)**
>
> Kiri:Moto is a unique 3D slicer that runs entirely in browser and creates output for your favorite maker tools: 3D Printers, CNC Mills and Laser Cutters.

> **[FreeCAD: Your own 3D parametric modeler](https://www.freecadweb.org/)**
>
> FreeCAD, the open source 3D parametric modeler
