From the project
32-bit 3D Printer controller board using STM32F407 and replaceable TMC2660/2209 stepper drivers.
PrntrBoard V2 ====================== PrntrBoard V2 is the next iteration of my 3D printer controller design. The V1 was very good, except it had one major drawback - the stepper drivers were soldered on the board which would make the design expensive. This V2 design has 6 replaceable motor drivers. While traditional RAMPS based boards use pin headers to house the driver boards, I'm using PCIe 1x slots. This design has several advantages: + the driver PCB layout can be more flexible as there are fewer constraints on the driver board dimensions + drivers are placed vertically on the board which…
