Not really an update but I have a good finding that I would like to share.
A friend of mine gave me three of those aluminium beams that he found as reinforcements in a box that had inside a big ladder !
It is like early Christmas, how can I use them at my build ?
First think that came to my mind is to cut the small square tube, the one that is weld perpendicular to the long one and use it as base for the motors and cut longitudinal the long part ,and use it as a support to L beam of Y axis?
Any thoughts ?
