Hi. You can use the stepper motors from old printers to build a cnc/laser engraver. You could also use the chips from those printers but it would take a lot of work and I wouldn't recommend it at all for a beginner. I recommend you to do some research on arduinos and step-stick motor controllers to begin with. They're cheap and there's plenty of information online
Hi. You need a power adapter that outputs 5V. If you get one with 5V 1A or 2A it will do.
Hi. I do not now any company that does that although there are some, for sure. If you don't need a big resolution maybe 3D printing could work?

Hi. If you find a way to program the PIC18F4550 using the Arduino, then yes, you can. But I don't know any way of doing it.

Thanks! I never heard of the QFR frosty flake controller and just took a quick look. If it has at least one available pin it could be used to trigger the circuit to turn on/off the flash drive but it would still need the USB hub. Was nice to find that the developer of the QFR frosty flake was the guy who wrote the keyboard firmware that I used as inspiration to write my own :)
Hi. The Teensy also needs to be programmed but there are some projects online that may have the code available for you to download.
Hi! The weight of the Dremel is not the problem. The rods handle the weight just fine. The problem lies on the big forces applied to the end mill during machining.
Hello mbjrgk, thank you very much for your kind words. I'm glad it was useful for you :)
