FDM 3D printer motherbords based on STM32F407VG/STM32F103RE This projects contains design of motherbords for FDM 3d printers. Where 3 variants of its:

  1. Mobula Ray. This motherbords based on STM32F407VG microcontroller. Motherbords contains:
  • 6 stepper motors drivers TMC2224 (same as TMC2208) controlled by UART. Microsteps, stepper are current controlled by firmware.
  • 6 PWM output - Heatbed, 3 x heaters, 2 controlled fans
  • 4 temperature inputs
  • 6 inputs for XMIN, XMAX, YMIN, YMAX, ZMIN, ZMAX
  • 3 inputs for filament detectors
  • BlTouch connector
  • onboard WiFi
  • connector for external GSM module
  • connectors SPI/I2C/UART interfaces
  • EXT1/EXT2 connectrs for displays/external SD card
  • SWD connector
  • USB-B
  • micro SD
  • switch after end of print output
  • connectors for 9 programmable pins
  • board size 150 x 120 mm
