Symptom Axis jitter, abnormal noise during movement, axis stuck, servo alarm, positioning deviation, machine running out of sync.     Possible Causes Loose wiring or poor contact of servo power line, encoder cable. Servo driver overcurrent, overvoltage or overload protection triggered. Parameter mismatch between servo drive and motor. Mechanical resistance is too large, guide rail […]

Symptom Laser source alarm pops up, no laser output, intermittent light emission, laser power drops obviously, machine stops cutting suddenly.     Possible Causes Abnormal communication signal between laser source and control system. Over-temperature protection triggered due to poor heat dissipation of the laser source. Optical fiber damage, loose fiber connector or contaminated fiber end […]

Symptom Unstable cutting air pressure, pressure alarm, intermittent air output, no gas discharge, abnormally high gas consumption, and fluctuating cutting section quality.     Possible Causes Insufficient gas cylinder pressure, valves not fully opened, or improper switching of the cylinder manifold. Damaged pressure reducing valve, fatigued pressure regulating spring, resulting in continuous output pressure drift. […]

The machine bed is the base of the fiber laser cutter. A dirty or deformed bed directly affects cutting accuracy and workpiece flatness.     Daily Check Clear metal slag and scraps on the worktable after each batch cutting. Check support strips for burning damage or deformation. Confirm no leftover parts jammed in the bed […]

The chiller cools the laser source and cutting head. Overheating will trigger alarms, reduce laser output stability and even damage the laser.   Common Symptoms High temperature alarm pops up Unstable water temperature fluctuation Low water flow warning Water leakage   Possible Causes Dust clogging on condenser Insufficient or contaminated circulating water Water filter blocked […]
