This has given me some insights into extruded layered manufacture and also produced a lot of scrap !
There are some facts and figures in my blog for anyone who is interested :-
There are lots more things I want to try but I have to repair my extruder first :-

Moulded RP Parts (at last!)
We can supply individual parts or complete kits of Moulded RP parts and in the next day or two should have complete kits of all Hardware our target price is under £300 + vat for a complete kit including motors etc etc....
Please also note the Moulded parts also included the Pulleys which have been moulded in to the drive connectors this saves $83.70 (McMaster) and also means the Y motor shaft does not need cutting down, if only we could mould the timing belts!!!
Please browse around the web site www.bitsfrombytes.com we are working hard to improve the site so as well as a shop it will also be a useful source of information, any comments would be very well received.

Machinist Help Needed
Basically, I need to find a machinist, or someone who is willing to spend 10-20 hours every few weeks to make me the parts I need. Since the response on the extruder kits was so good, I'd like to do an order of 50 sets of machined parts, and if that goes well, many future orders to follow.
Here's what I need, specifically:
50 x PTFE thermal barrier
50 x Drive Screw Assembly (ideally, already soldered)
50 x Heater Barrel (made from 3/8" aluminum studding. i only need it cut + drilled, no assembly required)
What I do not need suppliers for are:
although, feel free to get quotes on those as well. i sure wouldn't mind having someone else make those instead of me.
More details are on the mechanical parts wiki page.
What I'm hoping the community can do is go out, scour the internet, and solicit quotes from people and then either post them back here, or email them to me directly at firstname.lastname@example.org. One of the awesome, new things about open source hardware is that with many eyes, we can find the best prices and then pass that on to everyone else!
If you ask for a quote, feel free to mention that it is for the RRRF, send them the website, and just generally be honest and up front. Ideally, I would like to find a company that is interested in making these for us, but I'd be willing to get them from the right person, so long as they will be reliable and prompt.
Thanks, and good luck!

DXF Commandline Tools
I'm wondering if anyone has any experience with commandline tools for working with DXF files. Specifically, I'm trying to create a 'build script' for the McWire Cartesian Bot design, which is all DXF files. I'd love to be able to automatically create SVG, PDF, PNG, or EPS files. Its pretty much a requirement that the tools be free, but I also might be open to low cost or shareware based tools if they are cheap.
Please post in the comments if you have any suggestions.
