Roland is a trusted name in vinyl cutters and makes the legendary Modela MDX40 PCB Mill. Their desktop CNC, the monoFab SRM-20, boasts accuracy comparable to other manufacturers. However, the user experience is where the monoFab really excels.

Lessons from 3D Printers

There are no fancy lights or features, but the thorough documentation means using the machine is very clear. The monoFab uses different software for 3D parts, 2D parts, and on-the-fly 2D operations, but they all share a user-friendly approach. Once tool paths are defined, clicking “cut” starts the job, just like clicking “print” in popular 3D printing software. You can tweak the parameters, but often the default settings are acceptable.

A Straightforward Machine

If you want a small CNC mill from a trusted brand that can ace small jobs with the user-friendly workflow of a 3D printer, the monoFab SRM-20 is for you.
