Documentation 3D Files

Introduction

  The My-Neon is a 50W CO2 laser cutting and engraving machine, featuring an expanded 620 x 400 mm workspace and powered by the cutting-edge MKS LS ESP32 PRO controller. Designed for Makers, prototyping workshops, and small businesses, it combines high performance with effortless integration—offering 100% compatibility with industry-standard software like LightBurn and LaserGRBL.

Equipped with an integrated liquid cooling system (2.5L capacity), a dedicated high-pressure air assist compressor for char-free cuts, and a magnetic door interlock for active safety, the My-Neon operates on 220V while staying true to the My Machines 100% Open-Source philosophy.

Open Compatibility (LightBurn & LaserGRBL)

Plug, play, and create immediately. Native support for the most popular laser control software on the market ensures a smooth, restriction-free workflow for both beginners and professionals.

Clean Cuts with True Air Assist

Forget tiny plastic fans. The My-Neon includes a dedicated high-pressure air compressor, effectively clearing debris and smoke away from the laser path for flawless, char-free edges.

Thermal Stability & Active Safety

Built-in liquid cooling with a 2.5L reservoir protects the 50W laser tube and extends its lifespan. Includes a magnetic door sensor (Interlock) that instantly disables the laser beam if the lid is opened during operation.

Key Features

  You didn’t come this far to stop

Work Area & Design

F​eatures a generous 620 x 400 mm cutting bed, giving you plenty of room for professional projects. The machine is built into a fully enclosed cabinet with an integrated exhaust fan and a magnetic door sensor (Interlock) that immediately halts operations if opened, ensuring maximum workshop safety.

Laser Module

Powered by a robust 50W CO2 glass laser tube. It features an integrated 2.5L liquid cooling system to maintain optimal temperatures during long jobs, plus a dedicated high-pressure air compressor (True Air Assist) that blasts away debris for clean, char-free edges.


Control & Connectivity

Driven by the high-speed 32-bit MKS LS ESP32 PRO control board. Enjoy plug-and-play native compatibility with industry standards like LightBurn and LaserGRBL. Connect effortlessly via USB or go fully wireless using the built-in WiFi and GRBL Web UI.

Materials Supported

Easily slice through MDF, plywood, and acrylic up to 8mm, or cut softer materials like EVA foam up to 20mm. Switch to engraving mode for high-resolution, permanent marking on wood, glass, leather, stone, ceramics, and anodized metals.

The Brains of the My-Neon: MKS LS ESP32 PRO

At the core of the My-Neon lies the 32-bit MKS LS ESP32 PRO control board, specifically designed for digital laser fabrication.

  • High-Speed Processing: Powered by the dual-core ESP32 microcontroller, it delivers lightning-fast trajectory processing, eliminating stutters or pauses during complex, high-resolution engravings.
  • Built-in Wireless Connectivity: The integrated WiFi module allows you to send files, monitor job status, and adjust settings directly via your web browser or local network.
  • Flexible Open-Source Firmware: Built on an open architecture, granting you full freedom to recalibrate, update firmware, and customize stepper motor acceleration parameters.
