Well we figured we'd take it easy right before spring break since we know everyone has tests coming up. I'm going to bring in my Funbox, Jason is talking about his cloud chamber, and I think they're going to try and bring everyone up to speed with the quadcopter. I'm not the biggest fan of doing something like this so early but whatever. I'm just going to try and polish the Funbox off a little and cut some smaller things on the laser cutter just to show it off.
We also just decided to redo our club poster so I'm thinking I might use the cutter to engrave a wood plaque for it.

you could laser engrave and use the 3d printer, kill 2 birds with one stone

I'd like to, we need to figure out who we have to talk to/bribe/intimidate to show us the ropes on the 3D printer and scanner. Until then I kind of want to design something with depth like the pic below. I'd still engrave this but I think a layer or two of depth (can't go too deep/thick this is going on a bulletin board) would look awesome and grab peoples attention.  |

that is pretty cool. I used the plasma cutter in highschool, we also had to set a kerf. I am assuming that this is the same way with the laser cutter. We can create a test piece and figure out the kerf width from that, then we plug the numbers into autodesk and it does the rest.

I can leave the wood in my truck and we can go get it when we need it. Ill try to get some feeler gauges in the morning so we can try to make some precision cuts. These cad drawings have a number of random holes in them, we need to test if that is going to reduce the strength or not. we also need to cut down a 5' by 5' square to fit into the laser cutter.

sites.normandale.edu/kevinlee/He has office hours 11-12 tomorrow, you interested in trying some cutting tomorrow? I was going to pickup some scrap wood and/or cardboard on my way to class tomorrow so I have some material to just experiment with, what thickness did you get?. Also do you remember the dimensions of inside the cutter/maximum board size that'll fit? Do you have feeler gauges? EDIT: Just reread your post where you said the thickness was 1/18th, lol.

the maximum size is 12" by 24". Josh has some foam board to experiment with but I kinda want to use my plywood. I am going to buy some feeler gauges on the way to school but I will also bring my file set and my caliper. I want to cut wood tomorrow so ill have all my tools with me this time.

Kevin said that he would be down there at 8, do we really want to get up that early? I think we should talk to the dean and have these laser cutter's moved to better places.

Yeah I'm going to skip it. I need to redo some Inkscape designs and get more material.
