In the laser processing world, precision and speed are non-negotiable. Whether you’re cutting intricate patterns or marking at high speed, the performance of your galvo controller, laser cutting controller, and scan head plays a decisive role in the final outcome. This article dives into how these three components work together to deliver unmatched control and results in laser machines.
What Is a Galvo Controller?
A galvo controller is a critical component in laser systems that control the movements of galvo motors in a scan head. These galvo motors use mirrors to deflect laser beams at ultra-fast speeds across X and Y axes, enabling non-contact marking or cutting.
Galvo controllers communicate with laser control software like EZCAD, ensuring that laser pulses are synchronized with motion to achieve accurate output. A high-performance galvo controller offers features like:
-
Ultra-low latency signal transmission
-
High scanning precision
-
Real-time temperature monitoring
-
Support for 2D and 3D laser applications
Understanding Laser Cutting Controllers
The laser cutting controller is the brain of a laser cutting system. It manages the interaction between the laser source, motion system, and user interface. Controllers like JCZ’s LMC or DLC series are widely adopted in fiber and CO₂ laser systems due to their powerful processing capabilities and compatibility with industrial standards.
Key functions include:
-
Controlling laser power, frequency, and pulse width
-
Synchronizing axis movement with laser output
-
Supporting vector and raster cutting
-
Custom parameter settings for various materials (metal, acrylic, leather, etc.)
A robust laser cutting controller ensures smooth cutting paths, sharp corners, and optimized speed without sacrificing accuracy.
The Role of the Scan Head in Laser Systems
The scan head houses the galvo motors and mirrors that direct the laser beam. The speed and accuracy of the scan head directly impact the marking or cutting quality. Combined with a responsive galvo controller, modern scan heads can achieve speeds up to 10,000 mm/s while maintaining micron-level accuracy.
Features of high-end scan heads include:
-
Air or water cooling for stable performance
-
Anti-reflection coated mirrors
-
Dustproof and vibration-resistant housing
-
Wide field marking area options (e.g., 70x70mm to 300x300mm)
When paired with the right galvo and laser controller, the scan head becomes the execution engine of high-speed, high-precision laser work.
Integration Benefits
Integrating a high-quality galvo controller, laser cutting controller, and scan head provides:
-
Faster processing speeds
-
Higher accuracy on complex geometries
-
Improved compatibility with various laser types (fiber, UV, CO₂)
-
Long-term system stability with fewer calibration needs
This combination is ideal for applications like metal engraving, PCB marking, QR code laser etching, and high-precision cutting.

FAQ: Galvo and Laser Controllers
Q1: What’s the difference between a galvo controller and a laser controller?
A galvo controller handles mirror movement; a laser controller manages laser pulses and system logic.
Q2: Can I use any scan head with my galvo controller?
Not always. The scan head must be compatible with the voltage and signal type of the galvo controller.
Q3: Is a 3D scan head necessary for laser marking?
Not for flat surfaces, but for objects with height variation or curved geometry, a 3D scan head is recommended.
Q4: How often do galvo controllers need maintenance?
Minimal maintenance is required, but calibration and firmware updates are recommended annually.
Q5: Can the same controller be used for both cutting and marking?
Yes, many industrial controllers like LMCV4 and DLC2 support both functions through software configuration.
