3D printer controller (12V)

TIDA-00405

 
Overview

This design is a complete system for controlling a single extruder based 3-axis 3D printer. The system is managed by the MSP430F5529 LaunchPad and utilizes the DRV8846 for precision stepper motor control. The CSD18534Q5A is used as a low-side switch for warm bed heaters, extruder heaters, and cooling fans. The DRV5033 Hall sensor acts as a non-contact limit switch.

characteristic
  • ● Complete 3D printer controller including MCU, stepper driver, heater output, sensor input and SD card slot.
  • ● Use DRV8846 adaptive attenuation to achieve precise stepper motor current regulation
  • ● Hall sensor limit switches are not affected by contaminants and will never wear out
  • ● High current heater output from CSD18534Q5A with on-resistance as low as 7.8 mΩ
  • ● Powered by a single 12V power supply
  • ● The system has been fully tested and proven in practice
