From the project
A fully custom 3D Printer controller board based on an stm32f7 controller with TMC2209 stepper drivers
This Repo contains the design files for a fully custom 3D printer controller board. It is equipped with an STM32F7 Controller and uses custom-made TMC2209 Driver PCBs (also included in the Repo). The PCB was designed for using JLCPCBs Assembly service, so most of the SMD parts can directly be assembled by them. The Controller PCB is a two layer board, which makes production for hobby projects more affordable.
