Hi everyone, so im thinking on building a big sphinx. I love the design with the c-beam actuators. I want to build a big machine, but im concerned that it may start flexing when milling aluminium. How big can you go before c-beam starts flexing? I was thinking 1500mm length c-beams for both X and Y axis (not sure whats the real working area). Is this something ok for aluminium? Any other tip regarding building a big machine? Your advice is really appreciated, regards.
