About this document

Atmega GRBL CNC Controller Schematic by anhxco is a document available to read on EtoBox.

This document provides a schematic for a 3D printer controller board. The board uses four DRV8811 motor driver ICs to control the stepper motors for the X, Y, Z and extruder axes. An ATmega328P microcontroller controls the board and communicates with a connected PC over USB via an FT232RL USB-UART bridge chip. The board also includes connections for endstops, an EEPROM, LEDs, pots, connectors and other components required to operate the 3D printer.
