CNC GRBL 6-Axis ESP32 WiFi Breakout Board USB Motion Controller

CNC GRBL 6-Axis Breakout Board — ESP32 WiFi 32-Bit Motion Controller

Take your CNC projects to the next level with this powerful 6-Axis GRBL Breakout Board built around the ESP32 32-bit dual-core processor. Running at up to 240 MHz and featuring built-in WiFi at 150 MHz, this motion control card brings professional-grade CNC performance to your DIY router, laser engraver, woodworking lathe, or robotic arm — all controllable from your phone or tablet.

Key Features

• ESP32 Core Processor: 32-bit dual-core CPU running up to 240 MHz for fast response and rock-solid stability.
• Built-in WiFi & Hotspot: Operate wirelessly from your smartphone or tablet; WiFi speed reaches 150 MHz.
• 6-Axis Simultaneous Control: Connect up to 6 stepper motors or servo motors for complex multi-axis linkage.
• USB Motion Card: Optimized power-selection circuit ensures USB and external power don't interfere — connecting external power automatically isolates USB for a more stable data connection.
• Wide Power Input (12–24V): Automatic protection circuit disconnects power if voltage exceeds 30V (max 36V), guarding against over-voltage and reverse-connection damage.
• Tool Setting & Homing: Supports tool-length setting, limit switches, and origin/home return operations.
• 4 Macro Buttons: One-key tool setting, homing, tool change, and engraving start — no software required for common operations.
• PWM Output: Adjustable-voltage PWM output port plus a 3-wire laser output and spindle/water-cooled output port.
• Broad Software Compatibility: Works with Candle, CNC3DCommander, LaserGRBL, LightBurn, bCNC, GRBL-Plotter, and other GRBL-compatible software.
• Multiple Protection Circuits: Anti-over-voltage and anti-reverse-connection circuits for longer board life and safer operation.

Frequently Asked Questions

Q: What software is compatible with this CNC GRBL 6-axis breakout board?

A: This ESP32-based GRBL motion controller is compatible with a wide range of popular CNC software, including Candle, CNC3DCommander, LaserGRBL, LightBurn, bCNC, and GRBL-Plotter. Any GRBL-compatible host software should work seamlessly over USB or WiFi.

Q: Can I control this CNC breakout board wirelessly from my phone or tablet?

A: Yes! The board features built-in ESP32 WiFi and can create its own hotspot, allowing you to control your CNC machine directly from a smartphone or tablet without needing a dedicated PC connection.

Q: How many motors can this 6-axis breakout board support?

A: The board supports up to 6 stepper motors or servo motors simultaneously, enabling complex 6-axis linkage operations ideal for CNC routers, engravers, lathes, and robotic arm systems.

Q: What is the recommended power supply voltage for this motion control card?

A: The board operates on 12–24V DC. It includes an automatic protection circuit that disconnects power if voltage exceeds 30V, with an absolute maximum of 36V. Always use a regulated, stable power supply within this range for safe operation.

Q: Is this CNC controller compatible with Mach3?

A: This board is a GRBL-based ESP32 controller and functions similarly to Mach3-style motion controllers in terms of capability. It is not natively Mach3 software-compatible, but it supports many of the same CNC operations through its compatible GRBL host software options.
