Description

This design is a complete system for controlling 3-axis, single extruder-based 3D printers. 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 the hot bed heater, extruder heater, and cooling fan. The DRV5033  Hall Sensor acts as a contactless limit switch.

Features
  • Complete 3D printer controller with MCU, stepper drivers, heater outputs, sensor inputs, and SD card slot.
  • Precise stepper motor current regulation using DRV8846 adaptive decay
  • Hall sensor limit switches are immune to contaminants and never wear out
  • High-current heater outputs from the CSD18534Q5A with low 7.8 mΩ Rds(ON)
  • Powered from a single 12V supply
  • System has been fully tested and proven
