Generating G-code

This is the full CAM loop: define stock, choose toolpaths, verify the cut in simulation, and export controller-ready G-code.

Before you start

1
Set up stock and origin
In the Manufacture workspace, define the stock block around your part and set the work coordinate origin where the machine will be zeroed.
2
Face and rough
Add a facing operation to clean the top, then an adaptive clearing toolpath to remove the bulk of the material efficiently.
3
Finish to size
Add contour and pocket finishing passes so walls and floors come out at their final dimensions and surface finish.
Tip: Roughing removes material fast; finishing makes it accurate. Keep them as separate operations.
4
Simulate the cut
Run the stock simulation to watch the part emerge. Look for gouges, collisions, or uncut regions and fix the offending operation before going further.
5
Post and export
Select the post-processor for your controller and export the G-code. This is the same verified program the simulation just validated — ready to load on the machine.

Verified, controller-ready 3-axis G-code produced entirely inside HelioCad.
