Hello everyone, I am planning to build my first CNC ATC, and after many hours of internet research i am confident that can be done, i just need a little(or more) guidance. So, minim working dimensions that I need is 2100x2900 mm, so is quite big. I will use it just for melamine and MDF. For the parts, will be bought from China, 9KW spindle, cnc controller, 1KW servo motors and drivers. ( is that to much? ) And my questions at the moment are : What is the best material for the frame? rectangular steel or Vslot aluminium? ( I was thinking at something like 150x150 or 200x200 bars). Of course if steel is a better solution will be welded and cut by a professional locals but I still don't think will get perfect precision . I am interested on how can I get best precision Also, I have in mind all the mechanism, and what I need to know is, with the CNC controller, will I be able to make commands on how and where machine needs to go to change tools or is a complicated code writing? ( not expecting to be easy but I have little knowledge.
