From one fixed length to any length
A fabricator's cutting machine could only do one thing: cut to a fixed length. Every job that needed a different length meant re-planning the layout and swapping material — time lost before a single cut was made.
At a glance
- The machine went from fixed-length only to cutting variable lengths on its own.
- A crop-mark sensor tells the cutter exactly where to cut.
- Saves the prep time and the material swaps that every length change used to cost.
The situation
The client's machine cut to one fixed length and nothing else. So producing anything with varying lengths meant working around it — plotting how to lay everything out to fit the fixed cut, and changing material every time a job called for a different length. The machine dictated how they produced, rather than the other way round.
What we did
We added crop-mark sensing to the machine. A sensor detects the printed crop marks, so the cutter knows exactly where each piece ends and cuts variable lengths automatically — no fixed-length workaround, no re-planning each layout. We built it with an Arduino reading the sensor, a custom HMI for the operator, and the control logic in C++.
What changed
The machine now cuts whatever length the job needs, reading the marks instead of being told one length. The prep time that went into plotting layouts to fit a fixed cut is saved, and so is the swap time lost to changing material for every different length — production stops bending around the machine's one trick.
Why it worked
This is the kind of work we come from: getting a real machine on the floor to do more by adding the right sensing and control, instead of replacing it. A sensor and some control logic turned a single-purpose cutter into a flexible one.
A machine that only does one thing?
Often the fix is the right sensing and control — not a new machine.
