I made this 3D printer in Spring-Summer 2015, the main feature of this project is its anti-wobble system, it consists in the separation of Y and Z axis from Z screws, Y axis can moves freely on Z axis, because it's leaning on Z screws.
This innovation avoids the transmission of Z screws wobble to Z axis.
This printer has no XZ dimension limits (X structure limits Y dimension to 20cm, it's poorly designed ).
Extruder mount can be replaced with a PRUSA
(Tolerance is always 0,5mm)
