- The "Perfect Fit" Retrofit Direct Drop-In Replacement for M2/M3 Nano Boards. Engineered with the exact dimensions and hole spacing as standard M2 and M3 Nano boards, making the physical swap strictly "plug & play" for K40 upgrades. No drilling required. While standard speed is optimized for 0-500mm/s (typical for K40 mechanics), the board supports higher speeds if your frame allows, offering a flexible upgrade path.
- The "32-Bit" Core High-Performance 32-Bit GD32 Chipset & Stable Data. Powered by a 32-bit GD32 MCU with integrated A4988 drivers, this board processes G-code faster and smoother than 8-bit alternatives. It utilizes the CH341 communication chip and baud rate of 921,600, ensuring stable, high-speed data transmission without buffer lags or stuttering during complex engraving tasks.
- The "Smart Safety" Protocols Advanced Active Safety Features (Static Protection & Lid Check). Built for peace of mind. Features a "Static Laser Protection" system: if power >20% but the laser stops moving for 5 seconds, it auto-cuts the beam to prevent fires (time/power thresholds are adjustable or disable-able). Also includes ports for Lid Open Protection (stops laser when cover is lifted) and standard Water Protection, prioritizing user safety.
- The "Total Control" Config Fully Customizable Firmware Parameters. Unlock complete control over your machine's behavior. You can modify motor direction, define work area size (X/Y), adjust acceleration/speed limits, and calibrate steps/mm accuracy. It supports both mechanical and inductive limit switches (NO/NC) and allows fine-tuning of homing speed and pull-off distance to suit custom builds perfectly.
- The "Visual" Quality Precision PWM Grayscale & Adjustable Current. Achieve stunning photographic engravings with precise PWM laser control (0-100% power scaling). The board allows for adjustable motor current (run and hold current) directly via parameters, preventing skipped steps (layer shifting) while keeping motors cool. Perfect for users demanding high-detail output on wood and acrylic.
- The "Utility" Convenience User-Friendly Test Fire & EX3 Interface. Simplifies the focusing and alignment process with dedicated utility ports. Features an EX3 interface for adjustable Laser Spotting (Test Fire) power, allowing you to check beam position without burning your material. The "Axis Locking" feature holds the gantry firm during idle times to maintain absolute zero position.
