Do you want to not only engrave but also precisely cut with your Mr Beam? Then you need the right foundation: a clean cutting file.
Especially at the beginning, the topic might seem a bit complicated – but don't worry! With a few basic rules, it's quite simple.
In this tutorial, I'll show you step-by-step how to create a perfect cutting file for the Mr Beam – so your laser does exactly what you want.
Why is a good cutting file so important?
When laser cutting, your Mr Beam doesn't work like a printer with surfaces, but precisely follows the lines of your file.
This means: Only lines are cut – everything else is engraved. Of course, you can also move all cutting lines to engraving in the Mr Beam software, but this blog post will explicitly focus on how to create a clean cutting file.
So, if your file is not cleanly structured, problems can quickly arise: incomplete cuts, double lines, or unclean results.
Material for your laser design
- Mr Beam Lasercutter
- Design software (e.g., Inkscape, Illustrator, or CorelDraw)
- A vector file (SVG or DXF)
- Optional: Image file (PNG/JPG) for vectorization

Create design – Vector instead of image
The most important difference when lasering: There are two types of files.
- Vector graphics consist of lines and are perfect for cutting
- Pixel graphics consist of pixels and are only suitable for engraving
For cutting projects, you therefore always need a vector file.
You can either draw your design yourself or import an image and then vectorize it. Even purchased files, for example from Etsy, should be checked in a graphics program beforehand so that they can be cut cleanly later.

Use colors effectively
A very helpful trick in file preparation is working with colors. Because if the contour and surface have the same color, you quickly lose track of what should be cut and what should be engraved later.
Even if this post is about cutting files, this way of working is still worthwhile: Create your cutting contours in red, for example, and possible engraving elements in black. This keeps your design clear – especially if you add more elements later or combine different work steps.
The practical thing about BeamOS: The Mr Beam software automatically recognizes different colors in a file. This allows you to assign different jobs and even your own parameters to individual colors later, or to omit something. In our couch bar example, individual areas could be omitted thanks to the colors.
Tip: In BeamOS you can always split the file by line colors and shapes!

Prepare design – how to make your file laser-ready
Before you upload your file to the Mr Beam, you should definitely check it.
The laser will later follow your lines exactly – so they must be cleanly created.
- All lines should be connected
- Avoid duplicate lines
- Make sure there are no open paths
- Overlaps should be removed
Important: Every line will be cut – even if it is present twice.
The right settings in your design software
For your Mr Beam to recognize what needs to be cut, you should prepare your design correctly.
- Do not use fill
- Activate contour
- Set line thickness
It's important to know for the Mr Beam: The line thickness in your vector file does not matter for the cut. Unlike many other laser cutters, the lines do not have to be hair-thin to be cut. The only decisive factor is that a contour is set at all.
The laser itself will always cut with its actual beam strength – regardless of how thick the line is represented in your file.
Area vs. contour – the decisive difference
For your design to actually be cut later, one thing is particularly important: elements that are to be cut need a set contour, but no set area.
When cutting, the laser follows the vector lines. An area, on the other hand, is interpreted by the software as an engraving.
So, if you are working in Illustrator, Inkscape or another vector program, you should check for each object whether only the contour is active. This is precisely the basis for a clean cutting file.
Check file – the most important step
A simple trick helps you avoid errors:
Switch to outline mode in your software.
Here you see exactly what the laser will later recognize – namely only the lines.
If your design looks clean here, you're on the right track.
Setting size and position correctly
Make sure to create your design in the correct size. If you plan to cut your design from an A3 sheet, it is recommended to create the file directly in A3 as well.
It is best to work directly in millimeters and adapt your workspace to the Mr Beam.
This way, you avoid surprises later during cutting.
Export file and upload to BeamOS
Export your finished design as an SVG file and then upload it to BeamOS.
There, you can precisely place your design on the material using the camera preview.
Then select the appropriate material profile and start the laser.
If you have worked with colors, you can also assign the individual colored elements to different jobs in BeamOS. This is particularly practical if you later want to combine engraving and cutting elements in one file.
Avoiding typical beginner mistakes
- Using pixel graphics instead of vector graphics
- Duplicate lines in the design
- Open or unconnected paths
- Too many small details and anchor points
- Using set area instead of set contour
Tips for perfect cutting results
- Keep your design as simple as possible
- Test your settings on scrap material first
- Reduce unnecessary details
- Work with clear, clean lines
- Use colors in the file for better overview
- Check every object for contour and fill before exporting
The result: Clean cuts with your Mr Beam
If your file is prepared correctly, your Mr Beam will cut precisely and reliably.
The edges will be clean, the material will not be unnecessarily stressed, and your project will look exactly as you planned it.

Conclusion: The perfect cutting file is no coincidence
A good cutting file is created through preparation and a few important basic rules.
If you work with vector graphics, create your lines cleanly, use colors effectively for orientation, and check your design for contour and fill before exporting, nothing stands in the way of your next laser project.
I wish you a lot of fun experimenting and successful projects with your Mr Beam!
