One after another

Yep, one cube... err... not really a cube, after another. Trial and error it's a scientific approach, but AltLab cupcake can get on your nerves.

First of all, Violeta it's a kind of cupcake prototype with many and many hours of printing, so she can be a kind of moody and the standard setups on ReplicatorG doesn't apply to her, wich it's a kind of a bummer :p

Second, João Neves, Basílio and me, well... how should I put this, we are rookies on 3D printing matters, but very eager to take the bull by his horns :D

Now, yesterday at AltLab, we've started with a new ABS spool, a spool with some bad reviews from AltLab experts, they never got an usable print from it, so,with our natural stupidity we've engaged in empirical effort to calibrate the damn thing.

As you can see, after 4 hours of trials and errors we've give up and wen home... with a promise, let's investigate what is the correct way to calibrate it :)

Slice and dice it!

Before printing your "hot from the oven" 3D model, you'll need to convert it in a language comprehensible to your 3D printer. A 3D printer is a CNC machine with a extruder as printing tool, so the logical step was adopting the same programming language used in the CNC, which is GCode.
Basically it tells to the machine which dots should connect... yes, all machines work like games you have played as a kid :)
Well, after this brief explanation, let's take a look at Slic3r, it's just one of many STL-to-GCode translators developed for 3D printing. At first glance it seams more user friendly than Skeinforge, but lacking some options/features, but I guess the main reason is the development team behind Skeinforge is the same as ReplicatorG, the Makerbot creators!
So, why should I use Slic3r? Well, take a look at RichRap wrote an impressive, let's call an essay, about Slic3r, take a look at it!
