Viewers: G-code & side profiles

cncfoam.com gives you several floating windows to inspect a cut. They are draggable, resizable, and toggled in Settings → Tool interface.

The G-code viewer

Shows the exact commands being generated, colour-coded by type:

• Green — G0 rapid (non-cutting) moves.
• Blue — G1 cutting moves.
• Red — M8 hot-wire on.
• Dim — M9 hot-wire off and comments.

The active line highlights as the animation plays, and a 📋 Copy button puts the whole program on your clipboard. It is the quickest way to sanity-check what the machine will receive.

X/Y and U/V block-side views

Two 2D windows show the wire trace on each tower:

• X/Y — the left tower profile.
• U/V — the right tower profile.

Each has a toggle between two modes:

• Plane mode — the bare wire endpoint trace at the tower plane.
• Block-side mode — the cut interpolated to the actual material face, framed to the block, so it matches what you see carved on the 3D block face.

On a morph the two views differ (as they should — each end cuts a different profile). They draw progressively as the cut plays, and a red dot marks the live wire position.

Reset view

Reset view (Home/F) snaps the camera and every floating window back to its default position and size — handy after you have dragged things around.
