Re: Raspberry Pi based 4 axis controller - 9 years ago
Quotemrwolfe Not bad ideas. There are 2 spare pins ATM that could be used as select lines. Taking this idea to its logical conclusion, you could multiplex all of the motor control lines e.g Common Step, Direction, plus 7 enable lines for 7 motor channels. Only problem is that only one motor can be driven at a time. Another possibility is to have seperate X and Y channels with all the others muby mrvn - General
Re: Raspberry Pi based 4 axis controller - 9 years ago
Hi, I'm toying with the idea of building a 3D printer that has a graphical display for more options on what to display, networking to avoid the hassle with usb sticks or sd cards, live video so I can watch the printing while I'm cooking in the kitchen and maybe include the slicer. A Raspberry Pi might provide all that. Quotemrwolfe Extra pins are an issue because the GPIO only has 21 pins plusby mrvn - General
