Ive been a member of cnczone forums, but in the past I got suggestion to go with Wade o design as it was easy. I tried to build the machine first, but didn't get that 9 inches tube in the market. Some has advised me here to get from Industry but this costs too much. Can somebody guide me in building this also I want to place 4th axis too. Purpose of the machine is for building some parts and mould dies for my end use. I am ok with the size of Wade o design, but looking to go with u type tube and this would be my first build. I am reading here blackbox, but is this available in India?
