The First Project cut With the Mark III CNC July 24, 2009

Just before baby arrived several weeks ago, I successfully cut my first real project. And it only took 2 tries!

This is a trivet, in other words a thing to put a hot pot on. The design is a hilbert curve, actually 4 hilbert curves connected to make the one continuous line. The wood is cherry. I really like cherry because of how well it sands to a glossy finish.

A couple things I learned. If you cut cherry too slowly, it burns your bit. I think I can still smell the smoke in the basement. Also if you have 2 programs, one to cut the curve and one to cut the outside perimeter, and in between you change the bit and accidentally move the alignment, it, looks like this:

This is also how it looks before you give it a quick sanding.

Nice! As for the one due to misalignment, could you maybe cut off the edges to make it match?
