3D Printer & CNC Mainboards – Auscom

Upgrade or replace the brain of your 3D printer or CNC machine with Auscom’s range of high-performance mainboards.
These controller boards (or motherboards) handle all system coordination — from motion control to temperature regulation and communication between drivers, sensors, and motors.

What Are Mainboards?

A mainboard is the central control hub of your machine.
In 3D printers, it manages extrusion, heating, and motor control for precise layer-by-layer printing.
In CNC systems, it interprets G-code commands to move the toolhead with accuracy — whether milling, engraving, or cutting.

3D Printer Mainboards

  • Creality Boards: Compatible with Ender and CR-series printers. Available in 8-bit and 32-bit silent upgrade versions.
  • BIGTREETECH (BTT): SKR Mini, SKR Pico, and SKR E3 series boards that support Marlin and Klipper firmware for advanced motion control.
  • MKS Boards: Makerbase mainboards with excellent reliability and compatibility across open-source platforms.
  • 32-bit Upgrade Boards: Boost performance, reduce noise, and enable modern firmware features such as auto-bed leveling and silent-stepper technology.

CNC Mainboards & GRBL Controllers

  • GRBL Controller Boards: Designed for CNC routers, laser engravers, and milling machines using the GRBL open-source motion control platform.
  • Arduino-Based CNC Shields: Easy-to-use shields that combine with microcontrollers for DIY or educational CNC projects.

FAQs

What does a mainboard do in a 3D printer or CNC machine?
It acts as the control center, coordinating the motors, temperature sensors, and user interface while processing G-code instructions.

Can I use a 3D printer mainboard for a CNC machine?
Some mainboards support multiple firmware types (e.g. Marlin or GRBL), making them adaptable for both 3D printing and CNC control.

What is GRBL?
GRBL is an open-source firmware that interprets G-code and controls the motion of CNC machines such as routers, mills, and engravers.

Do you stock 32-bit mainboards?
Yes — Auscom offers advanced 32-bit mainboards for both 3D printers and CNC machines, providing smoother motion, quieter operation, and enhanced precision.
