yes, the work size i want is about 600X400mm only, i would use only for make exhaust flanges and some parts like that, not bigger parts really.

about plasma, i really dont care if cuts are slower, i just want to make my own parts and to get decent cuts , of course i want to build a "cheap" machine, not the cheapest and not the waste a lot of money in this first cnc plasma of course.. just i need to introduce in this work and learn how this work exactly. once i get this working , i think it should be easy to improve everything.
