Maybe a year or so ago I tried to use eMachineShop, after it was posted to slashdot. Unfortunately they don't accept standard CAD files like DXF, etc. You must use their proprietary software to design your part. The software claims to be able to import DXF, but when I tried it on an incredibly simple 2D shape I wanted to have laser or waterjet cut, it totally mangled my design. I still liked this whole idea they have of getting real time pricing, etc., so I took the time to work through their software and redesigned the part. After much trouble, I finally was able to get a price for the part, and it ended up being at least twice as expensive as the quotes I had received on the same part from a traditional machine shop. Perhaps other people have had better luck or things have changed in the last year. I personally don't relish the idea of spending a lot of time becoming an expert at a new CAD package that can only be used with one shop and lacks many useful features of a package like Autocad, only to be able to order overpriced parts. -Holly Jeremy Grosser wrote: > Hey, > I just got the September issue of Wired and read the article entitled > "The Dream Factory" about a company called eMachineShop that will > machine custom parts based on a CAD drawing submitted online.

Hello everyone, I often use lasercut acrylic to make custom cases too. In fact I had been putting together a tutorial on that for the web a few years ago but had never finished it off. This thread inspired me to complete the tutorial last week, which is now availble here: http://www.positron.org/projects/acrylic_cases/ In the Collection section, you can also see some of the cases I have done at E Ink for gumstix based electronics. Separately, I gave a paper at SID this year in Boston on a project which used a gumstix. If you want to read the pdf of it, you can get it here: http://www.positron.org/projects/A51/paper.shtml Enjoy, -Holly Nate W wrote: > www.pololu.com will laser-cut acrylic for reasonable rates.
