Key Advantages of PLH3D Heads
- Industry-proven blue-laser architecture with compact, robust housings designed for CNC environments.
- Square or near-square beam shaping in XT-series for crisp rasters and uniform kerf across the cut.
- Wide control compatibility via PWM/TTL (0–24 V), easy wiring to popular CNC controllers.
- Air-assist nozzles and mounting ecosystem (LaserDock, dedicated mounts) streamline daily use.
Compatibility & Setup
PLH3D heads integrate with a wide range of CNC machines (including GRBL-based, Mach3/Mach4, and OEM controllers). When building your own set, remember to select the appropriate machine mount and signal cable. XT-series heads benefit from high-NA collimation and air assist; the LaserDock quick-release mount accelerates tool changes and storage.
