I'm not a part of the Makers group, but I have followed since you guys<br>
were meeting in each other's residences. I'm curious about the laser<br>
cutter. Will it cut fiberglass, carbon fiber, and/or kevlar cloth?<br>
Not cloth with resin, just the raw cloth.<br>
Now that the shop is so close to my house, I have been seriously<br>
considering joining your band of Makers in hopes of learning more ways<br>
to create/destroy stuff.<br>
