I spent some time last week getting the Chicago Public Library Innovation Lab set up with a special Shapeoko made by Edward Ford. It is fully enclosed with an integrated vacuum system, so it is both clean and quiet. It has a special spindle too, which makes it even quieter than the laser cutter air filter system!
The first job we ran on it after I fixed a couple calibration issues with it was a driftwood sign for a guy who wanted to make a number plate for his parents house for the holidays. Inexpensive but very thoughtful gift!
