G-code Viewer
Preview G-code extrusion layers, travel moves, speeds and estimated toolpath bounds before printing.
Workflow type: Interactive print-path viewer. Status: Functional. Expected result: Interactive viewer. Available action: Open print-path viewer.
What this 3D tool provides
Open G-code online to preview extrusion layers, travel moves, available speeds and estimated bounds before sending a job to a printer.
- G-code Viewer brings G-code input and an interactive inspection result into one review sequence.
- Use the before-and-after labels for orientation, then confirm the selected file with the result guidance and format notes below.
- Accepted input: G-code (.gcode, .gco, .gc).
- Available controls: Color mode, Show travel moves.
- Review the loaded layers, extrusion and travel paths, available speeds and estimated bounds. This viewer does not create printer-ready G-code.
How to use G-code Viewer
- Choose a supported file — Choose G-code (.gcode, .gco, .gc) from your device.
- Review settings — Review the available controls: Color mode, Show travel moves.
- Inspect the result — Orbit, zoom and inspect the loaded 3D data and its reported details.
Preview and result review
A spiral vase toolpath makes walls, travel moves and layer progression immediately readable.
- Before example: A spiral vase G-code file ready for print-path inspection
- After example: The same spiral vase shown as a colored layer-by-layer toolpath preview
Interactive print-path view: Review the loaded layers, extrusion and travel paths, available speeds and estimated bounds. This viewer does not create printer-ready G-code.

Frequently asked questions
What does G-code Viewer do?
It draws the toolpath by layer and distinguishes extrusion, travel and available speed information.
Which files does G-code Viewer support?
.gcode, .gco and .gc text files with supported motion commands can be previewed.
Is my 3D file uploaded?
Supported file contents stay on this device while the selected tool runs; site analytics and the assistant are separate. The selected file is not uploaded for the supported processing workflow.
What should I review after using G-code Viewer?
Always review printer profile, material, temperatures, limits, start and end commands in your slicer and printer software before printing.
