RepStrap: bigger parts...

I am finally starting to work on my projects again. I have taken an extended break from it all in order to spend more time with my wife between her classes. After returning to my projects the first challenge that I attempted to conquer was a common warping issue when printing ABS plastic. It wasn't really an issue when printing corner brackets and motor couplings. However, bigger pieces like the x carriage were near impossible. Luckily the solution was handed to me by nophead. It is clearly described in his Thoughts on rafts entry. After taking his suggestions into account I was finally able to print the x-carriage. Here are some pictures.
