Changes

So, there have been some changes. Instead of a Makerbot Cupcake, we will build a RapMan 3.1 from BitsFromBytes. It's bigger, badder and, as far as we've heard, a bit more reliable and precise. It's been ordered, and now we'll have to wait a few weeks for the machine to arrive, before we can start playing. 
One of the drawbacks of the RapMan is that it doesn't have a heated build platform (unless we make it ourselves), so warping could become a problem for us. Some research into potential solutions lead us to some special PLA material from a german company called Orbi-Tech, that is said to be warp-free, so we also ordered a load of that to test it.
Until we get all our stuff, here's a picture of the Rapman from their website.
