![]() ![]() Use cable that can take the current, and get shielded if you can afford it. Just gotta cut slower I guess Just a tip: wiring matters a lot. I've got a rather large CNC router based on roller chain and steppers and you really can't do anything once you lose a step because you don't know until the job is finished. The best thing I have seen with linux is the mesa FPGA cards: and the best with mach3 is the smoothstepper: I have one of those usb things you have linked to, never was able to get it working all that well (but I didn't try very hard tbh because the parallel port turned out to be fine) I am building a new 3 axis machine with servos/encoders/geckodrives and a smoothstepper. If you don't want that, you need to decide if you are going for linux CNC or mach3 as it changes things. As mentioned, parallel port is usually a pretty solid choice as most stuff supports it (and it's super cheap/free). They are a lot more complicated than you think I tinker a lot with diy cncs. Well, my first CNC was supposed to be 'just a tool'. ![]()
