Hey all, I am brand new tot his so please forgive me when I ask silly questions to first and foremost if I was to try to machine aluminium, what type of spindle am I looking at. I see the motors go from small up to 1,200 nm so was hoping someone could give me a tolerance to aim for. 2 I see 3/4/5 axis controllers. if I wanted to make a machine that rotates base on 2 axies ( so like record player and then back over top to front) and then have gantry move forward back, and then left to right and up down that makes 5 axes right? so what if I want eh spindle arm to move on another 2 axes AND have a second arm.... does that make it 9 axis? or is it only 5??? 3 someone will probably answer this with the above question but does the spindle arms use the same controller as the other axes? or is there a controller available to allow multiple heads doing different things so as to make a multipurpose machine 4 I see that Arduino is trying to make its imprint on the world. but the latency from computer to motor is hectic. is there an opensource micro controller that does not have this issue? 5 where can I find gcode makers for 5 axis (or 9.... ) machines? and as there are several types of 5 axis are they customisable to accommodate my set up 6 this will be the last question hopefully. what is the cheapest yet half decent cnc machine on the market. not the engraver ones. I am aiming for a build size of about 30cm cubed.
