I'm in, and have a friend off the list who is also in.<br><br>The biggest issue is sourcing the very specific parts that are usually purchased from mcmaster in the states. Options would be to get a trusted third party in the states to re-ship the parts for us, or alternately we source the parts in Canada.<br>

Sorry everyone, the original link was here:<br><br><a href="http://hackaday.com/2010/06/21/100-cnc-mill/" target="_blank">http://hackaday.com/2010/06/21/100-cnc-mill/</a><br><br>and via the comments there was this updated version:<br>

<a href="http://makeyourbot.org/mantis9-1" target="_blank">http://makeyourbot.org/mantis9-1</a><br><br>That one has enough details to actually consider building it. There's some improvements I would want to do (especially replacing the epoxy with a clamp as mentioned in the hackaday comments)<br>

Let me keep looking, I swear I had found a version of this CNC with much more detailed build instructions from start to finish.. The link I gave earlier might not have been the exact one that had enough instructions I felt comfortable that I could complete it from start to finish.<br>

<div>At the very least I would assume it does not include the interface circuit (which at it's simplest if it's using a parallel port and EMC2 to drive it. Cheap 3 axis stepper boards on ebay are still going to run you a couple hundred... Although 3x pololus with direct interface to parallel port would only cost about $40 plus shipping, and would easily drive a small scale 3 axis CNC, depending on how well the mechanics work.<div>

Motors are included in the $100, but it assumes that you have a computer with a real parallel port available for driving the stepper motors. So any old pentium-era desktop would suffice.<div><div></div><div><br>

Hi folk,<br><br>After makerbot & CNC conversations taking place on the list I figure this would be a worthy proposal.<br><br>I ran across a CNC build that is the simplest I have ever seen: <a href="http://fab.cba.mit.edu/classes/MIT/863.09/people/dcarr/final/final.html" target="_blank">http://fab.cba.mit.edu/classes/MIT/863.09/people/dcarr/final/final.html</a> . There is a BOM on there, it's only around 20 parts.<br>
<br>Is there anyone interested in doing a group parts buy/build of this CNC? It's not huge, it won't do everything, but if you're like me you'd probably love a little CNC.<br><br>There's about 20 parts and it costs under $100 to build. If we had a group I'm sure the price will go down and so will the complexity.<br>
<br>Anybody interested?<br><font color="#888888"><br>Tom<br><br><br><br>
