Hello, my name is Mariano and i'm planning to buy c-beam bundle machine kit as this is my first attempt in this kind of machines and i'm living in Argentina, where separate parts are not easy/cheap to get. My question is, if I buy c-beam machine bundle including 3 Nema 23 stepper motors, costing us$ 565.- what other thing would be necessary to buy? Stepper motor drivers? Power supply? Parallel port breakoutbox? What do you recommend? I mean for receiving everything to start working as soon as i received my package. Now, refering to software, i know you recommend Sketchup free for designing. What other software is necessary to communicate with motors? And for obtaining GCode? I plan to make PCB circuit boards, what is the best free software?. Very IMPORTANT I use Linux OS, any recommendations? I really appreciate your help, i am completely new and excited t start working.
