32bits is the future of 3D printing.
The latest marlin had ported to stm32 board,everything works, stable and smooth,have BLTouch,etc.
1)Use the easiest IDE tool that I developped for Marlin STM32 instead of arduino IDE;
2)source code link:https://github.com/hackaday3D/marlin_stm32
3)Integrated 5 silent stepper drivers TMC2208,control it through uart.
4)Auto controlled Fan on big cooling fins shell,prevent fan from pulling in dust to motherboard directly.
5)with board monitor temperature sensor, software can control the Fan automatically and protect printed model as stepper driver will reboot while over temperature.
6)lower price than any other 32bit motherboard, almost the same as the 8bit board.
