Hi!! I´m Carlos from Portugal, i was a owner of a Shapeoko 2 CNC but i sell it because i´m going to work to another country in France, now i want something more strong where i can use to machining Aluminium and plywood, i´m looking for something like 1000mm/1000mm in x/y but i would like a great accuracy. So i´m looking in openBuilds, i planning to design my own CNC based in the others one you have here. I have some ideias to share with you and discuss: - Controller using GRBL or Tinyg because i want to use chilipeppr. - All motors Nema 23 - Z axis 250mm with new C-beam with 8mm acme leadscrew - for X and dual Y: i´m not sure in what to do, if i go to timing belt like i have in my shapeoko or if i use rack&pinion to get more rigidity but i want to keep good accuracy?what is your opinion? This is my first doubts i have before starting my design.
