Come on, admit it. You have done it. We did it.You know-you are real Make sure that the plastic stock you found around the hackerspace is acrylic, right? You dial in the settings, load the design, set the focus and press the small green “Start” button. When you rush to the red “Stop” button, a lot of black smoke, fire, and general adverse reactions follow, then lift the lid to figure out how you will clean the button.
That is not acrylic. That is polycarbonate.
What you need is the latest gadget from MIT: SensiCut: Intelligent laser cutting system, which can automatically detect different materials.
This technology uses so-called “speckle imaging,” in which the material irradiated by the laser will produce a unique pattern of reflection points, or speckles enter the camera. By using a large number of samples to train a deep neural model, it was found that up to 30 types of materials can be detected with 98% accuracy.
The pre-baked model runs on Raspberry PI Zero and comes with an off-the-shelf camera powered by a mobile power supply. This allows the entire assembly to be simply placed on the existing laser cutting head without wiring.
Even if you are an experienced laser cutting machine user with good inventory control, this is definitely worth your peace of mind.More detailed instructions and more videos can be found in the following ways Read the full text. I hope they will release the system as open source one day in the near future. If not, then, you know what to do 🙂
