About
Open any gcode file and see exactly what your 3D printer will print — before you start. Gcode Viewer renders the complete toolpath in 3D: rotate, zoom and pan the model, scrub through every layer, and measure real distances in millimetres.
WHAT YOU CAN DO
• Open gcode from your slicer, Files, iCloud or a share sheet
• View the print in 3D — top, front, side and ISO
• Scrub the layer slider to check the print builds correctly
• Measure distances and the print height
• See print time, filament weight and cost estimates
• Follow a running print layer by layer
Built for makers who want to check a file before committing filament and time.
