Before the machine
Most failed laser jobs fail in the file, not at the machine. These pages cover the design and file-preparation skills that decide whether a job runs at all — and they are the skills that transfer between every piece of software a program might use.
The core concepts
Vector and raster artwork — what is the difference?
Paths versus pixels, and which operations each one drives.
Vector cutting versus raster engraving
The same distinction from the machine’s side, for more advanced users.
What is laser kerf?
Why a part cut on the line is not the size of the line.
What file types do laser cutters use?
What the common formats do and do not preserve.
What is an SVG, and why is it useful?
An open, text-based vector format that behaves predictably.
Preparing a file that will run
How do strokes, fills, and colors map to operations?
The convention that tells the machine what to cut, score, and engrave.
Why convert text to paths?
The single most common reason a file opens wrong on another computer.
How do I keep a file at the correct size?
Unit and scale checks that catch a part built at the wrong size.
How should I prepare an image for engraving?
Getting a photograph to engrave as something other than a grey smear.
Why are duplicate lines and open paths a problem?
Two file faults that waste time, material, and add fire risk.
Before it goes to the machine
What should a teacher check before approving a file?
A short preflight a teacher can run during a class period.
What should a university preflight check?
The equivalent for a shared lab with many users and higher throughput.
What is a good first project?
Measuring, designing, and testing in one small, finishable job.
Where to go next
- Start here — what the machine does, if the vocabulary is new.
- Troubleshooting — when the file looked fine and the cut did not.
- Higher education — kerf measurement and press-fit tolerance in depth.
