FreazyKam User Guide#

FreazyKam turns a drawing into G-code your CNC router can run. It works entirely in your browser — nothing is uploaded, nothing is installed, and your projects stay on your own machine.

This guide is task-first: each page walks a job from start to finish. For a plain list of everything the app can do, see the feature list.

Start here#

1. Quick Start — your first part Draw a coaster, pocket a recess in it, cut it out with holding tabs, simulate the job, and export G-code. About twenty minutes, and it touches every part of the app you will use on every job afterwards. The finished project is 01-circles.fkam.

Working in the app#


2. The canvas	Getting around, selecting, the Properties panel, transforms, groups, constraints, the pen tool, point editing, path tools, tracing a picture
3. Stock, origin and tools	Where zero is, which way the machine's axes run, the tool library, the two angle conventions, feeds and speeds
4. Operations	The shape of every operation form, pick order, Start height, the Objects strip and the Toolpaths list, regenerating

Cutting things out#


5. Cutting with an end mill	Profile and cut side, holding tabs, the five pocket strategies, trochoidal slotting, drilling, surfacing
6. V-carving and inlay	V-carve, photo V-carve, the geometry that makes an inlay seat, and fluting to a height profile you draw
7. 3D work	Importing an STL or a depth-map image, placing it, roughing and finishing a relief
8. Parametric parts	Gears, escapements, the clock designer, cams, cutting boards, track, joinery (box, finger joint, dovetail seam, bowtie), mazes, spirographs
9. Nesting	Packing parts onto a sheet, and leaving the offcut as one usable piece

Getting it to the machine#


10. Simulating and exporting	The simulator and its readouts, post-processor profiles, the G-code review
11. When something goes wrong	Open-path refusals, missing tools, stale operations, wrong size, wrong depth
12. Running the machine	Driving a FluidNC controller over WiFi: the one-time relay setup, homing and zeroing, jogging, the SD card, running and stopping a job

Help from an AI assistant#


13. Working with an AI assistant	Letting Claude or another MCP-capable assistant draw parts, make toolpaths and check the job for you: setup, what it can and can't do, undo, privacy

Boards that need more than one setup#


14. Double-sided and tiled jobs	Cutting both faces of a board on dowel pins, and cutting a board longer than the machine in tiles

Conventions used here#

Millimetres are the storage unit. The toolbar has a mm/inch toggle that changes what you see and type; it never changes what is stored. Switching units mid-project is safe, and a project saved in inches opens correctly for someone working in mm.
Stock is the material on the table. Point is a node on a path. Tool is a cutter in the library. The app uses these words consistently, and so does this guide.
Keyboard shortcuts are also listed in the app under the ? button, top right.
Screenshots are captured at a fixed viewport so they can be recaptured after a UI change and still line up. The rules are in images/README.md.
