如何查看 GCODE、GCO、NC、TAP 文件

Actual G-code behavior depends on the printer, CNC controller, and firmware. This viewer plots textual motion but cannot simulate machine dynamics or guarantee safety.

  1. Choose a .gcode/.nc/.tap file and select print or CNC mode.
  2. Review detected units, absolute/relative mode, bounds, and layer information.
  3. Scrub layers or play the path, distinguishing rapid from cutting/extrusion moves.
  4. Search homing, temperature, tool-change, and work-coordinate commands; correct the slicer or CAM source.

Kegunaannya

  • Quick preview without launching slicer or CAM
  • Layer/path checks for travel and bounds
  • The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.

Kompatibilitas dan batasan

  • Macros, subprograms, vendor extensions, and five-axis motion may be unsupported
  • Time estimates omit real acceleration, firmware planning, and tool changes
  • A preview cannot prove machine, fixture, or work-coordinate safety

Pertanyaan umum

Can it predict print time accurately?

Only roughly; firmware acceleration, flow limits, and machine state change actual time.

Why is the path outside the bed?

Check inch/mm units, G90/G91, work zero, and slicer bed dimensions.

Can I send this directly to a machine?

Do not run from a web preview alone; validate in the target controller and dry-run procedure.
