The structure follows the same schemes Mecaduino mechanical system with raceways made of stainless steel and bearings supporting the various strands of hardened steel and rectified, with a double row of balls that ensure zero backlash besides great resistance wear.
The useful work surface is 297 mm in the Y-axis, 420 mm along the X axis and 80 mm in the Z axis in its basic configuration. This measure can be expanded by replacing the pillars by larger ones. This is done in seconds and the cost of the pillars is very low.
