Why ?

Why not ? More seriously, because I wanted an accurate and reliable machine. I am very happy with my Prusa I2, besides it's become a young mother. But it does not allow the speed and accuracy (expected) by his son.

Less specific

At the moment I can not find an alternative to the trinitylabs set : 10 start 25mm pitch fast lead screw and nut.

Half speed, 1/4 the price, but to short, 200mm : 10 threads per inch and has 5 starts, 2 turns per inch. http://buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi

If any one know any other providers, I would be happy to know.

Others way could also be considered, such as threadless ballscrews

To do? or not to do?

Better implementation of endstops.
Change the extruder for a geared version.
~~Change NEMA17 3.6 kg/cm by 4.8 kg/cm for X/Y~~ - Done!
~~Speeds and quality tests.~~ - Done...
Find less specific alternative lead screw.

Preparation of the base
Integration of the Y axis
First try to mount the Z axis. Not great, too flexible in the horizontal motion (X axis).
Second try, with a more rigid mounting.
After wiring
wooden plate (temporary)
Ready to print (again)
