RestoreRapids

RestoreRapids is a small Windows GUI app that fixes missing rapid moves in Fusion 360 generated G-code. This tool was created as a work-around for the limitations of the free version of Fusion 360. It scans for retracts to a safe Z height and then ensures the next XY travel move is a rapid G0 when it is not already explicit or modal.

How it works

• Reads the input G-code file line by line.
• Strips comments for parsing so comment text does not affect detection.
• Detects a retract line that includes a Z word at the configured safe height within a configurable tolerance.
• After a safe-Z retract, the next XY move line without an explicit G word is modified:
  • If motion mode is already G0, the line is left alone.
  • Otherwise, G0 is prefixed to force a rapid move.
• Writes the updated output file and reports how many rapid moves were inserted.

Explicit G words on the next line (such as G0, G1, G2, or G3) are respected and will not be overridden.

Usage

1. Download the latest release: download.
2. Run restorerapidmoves.pyw or the downloaded .exe.
3. Browse to select your input G-code file.
4. Choose an output file location (auto-filled by default).
5. Set your Safe Z height (mm).
6. Set the Z match tolerance (mm) if needed.
7. Click "Fix G-code".

The updated file is written to the output path and the app displays the number of inserted rapid moves.

Inputs

• Input G-code file (.nc, .gcode, .tap, or any file).
• Safe Z height (mm).
• Z match tolerance (mm).

Output

• A new G-code file with G0 inserted immediately after safe-Z retracts when the next XY move does not already use a rapid motion.
