For a school project me and some other students were tasked with making and driving a CNC machine with our own hardware and software. I will only be posting the hardware here since that was my task.
I designed 3 PCB’s
-Powerboard
-microcontroller board
-stepper motor driver board
To keep the cost low the boards were max 100x100mm and were made modular and stackable with components spaced far enough apart so if any changes had to be made it could easily have been done without having to order a new board so we wouldn’t be short on time.
