Well ive done a bit of reading and searching and I have a few questions. Excuse my ignorance, I dont know alot about CNC....yet. I want to build my own CNC plasma table to build some flat 3/16" steel parts for a company im starting up involving air suspension for vehicles. I would like to keep the table as simple as possible, and dont need it very big. A 4x4 table would be perfect. I have read a few things about 'Z-axis' and needing a voltage monitor height adjustment or something? Why is this needed? Could I make the table simply x & y axis's and have the Z axis as a mechanical adjustment for when I want to cut a different thickness material? As for the parts im cutting, they dont need that high of precision, it would just be nicer for cutting circle plates etc on a CNC rather than doing them by hand. Also, the electronics side of this project (servos, motors, computer boards, etc etc etc) is REALLY intimidating me. I dont know alot about the programming side of computers besides html work (which, lets face it, is fairly simple compared to this stuff haha). As for the table...I shouldnt have too big of a problem doing the physical side of the table. I can grind, drill, weld, and all that with no problems. Can someone give me a link of someone who has built a very basic table? Also, what should I expect this to cost me (not including the plasma i choose)? One last question, what is the most common method of triggering the hand held plasma torch. Id like to be able to not have to rewire it as I will be removing it at times to use by hand. Again, excuse any ignorances I have, the veteran's of the site are probably laughing at my stupidity...lol. Anyway, Thanks!
