I’ve had my home made CNC machine for more than a year now, and I built it originally to make things out of metal. But I never dared, since I didn’t find a good way to cool it. Now I realized that I could take a shelf from my kids IKEA furniture and put it under the metal to be routed, and submerse the metal in water. It worked great. Well, the gear is the wrong size… but the quality is excellent. I’m going to try to use the same mechanism to make a hot end for my next plastic printer.
