== a large CNC machine | == SHAPEOKO == | ||

there is a large CNC machine suitable for soft materials like soft wood and plastic (and possibly harder materials?) located under the table in the southwest corner of sudoroom. It's made of wood and acrylic, and the wood is painted white. Nicholas cleaned it really well but inside there was still a rats nest, and they had chewed through some of the wires. Presently the XYZ stuff is working fine with a 12V power supply, but the DC motor controller for the spindle is pretty dirty from rats and the wiring from the 48v power supply to it (and e-stop and speed control) are all disconnected right now. A bench power supply could operate the spindle very easily though. | |||
