I bought 2014 my first printer and additional build some ultimaker clones. I liked the Ultimaker Clone, because the printer is nearly developed with custom parts that can be bought everywhere. What I liked is the small an clean SMD Ultimaker hardware, but I search for the possiblity to replace the Ultimaker electronic with the raspberry pi. With Octoprint there is the possibility to print directly but you still need the Ultimaker board or an Arduino with ramps. My goal is to reduce the electronic hardware only to the stepper and Heater electronic but at the minimum size as the Ultimaker Hardware do.
Is there a project or a possibility to use the raspberry as Mainboard and the IOs for the endstops and fans add only a SMD build PCB driver board to build the 3D printer electronic? The RAMPS board is cool but to chunky.
Then I have a printer with custom parts (such as aluminum profiles) , the Mainboard is the famous raspberry pi, the octopi sw and the only thing that isn't custom is the driver board.
Thanks a lot
