MKS SERVO57B

Features

Based on the open project of nano_stepper by Misfittech

To improve performance, Makerbase Team has made the following changes:

  • Ported the project to STMicroelectronics' 32-bit MCU, STM32F103CBT6 ARM 32-bit Cortex™-M3 CPU Core,72 MHz maximum frequency,20k RAM. 128k Flash
  • Changed the magnetic encoder to Allegro's A1333LLETR-T Contactless 0° to 360° angle sensor IC ,12bit
  • Ported the compilation platform from arduino to PlatformIO —— Convenient for STM32 MCU compilation
  • Change the socket with motherboard, now it can work with much 3D printer motherboards using MKS SV_EXT V1.1 by Makerbase

Firmware

This project support build and upload by platformio, you can use Atom or Code editor (need install platformio) build it or upload firmware. Please refer to the following method:

How to Build

Open platformio.ini file, set default_envs = mks_servo57b Other operations are the same as MKS SERVO42B(https://github.com/makerbase-mks/MKS-SERVO42B)
