|Laser power supply switch is not on
|The laser pressure threshold is too small
|Increase the laser pressure threshold
|The potentiometer knob is screwed to the minimum value.
|The current is too small, increase the current
|The water pump is turned off (water protection automatically opens).
|Turn on the water pump
|Bent water hose or blockage because of dirty water (water protection automatically opens).
|Check the water hose or water pump, to ensure clean and unblocked circulating water.
|The switch is not turned to the laser mode.
|Turn the switch to laser mode
|Damaged or aging laser tube.
|Replace the laser tube
|Loose wires of the laser tube.
|Ensure all wiring is ok. No wire coming out.
|Damaged laser power supply (indicator of the laser power supply doesn’t light)
|Replace the laser power supply
|Water protection device doesn’t work
|Replace the water protection device
2. Distinct fusing edging during laser cutting.
|The laser pressure threshold is too large (the starting point is burnt)
|Decrease the laser pressure threshold
|The output laser power is too large
|Decrease the laser current
|The cutting speed is too slow
|Increase the cutting speed
3. Weak laser cutting ability.
|The service life of the laser tube is over
|Check the color of the light beam in the laser tube. White light beam indicates laser tube should be replaced; violet color indicates the service life of the tube is not over yet.
|Any dirty lens of the three reflexes can affect laser energy. Check and clean the reflex lens and focus lens.
|If focal length is not proper, laser energy is decreased.
|Water temperature is too high
|The water container mustn’t less than 25Liter. If water is not enough, the water temperature rises easily. When water temperature rises, the laser energy is decreased.
|Speed excessively fast
|Decrease the speed properly
4. Carriage is sluggish or fails to rise.
|The switch is not turned to the plotter mode.
|Turn the switch to plotter mode
|Damaged elastic piece under the carriage cover
|Replace the elastic piece
|Burnt drive coil
|Replace the drive coil
5. Poor cutting effect or skipping cutting.
|Uneven surface of the white strip
|Flatten the bar or replace it.
|The knife holder is clamped too high
|Adjust it to proper position
|The carriage hits with some object under the bottom.
|Clear off the object.
|There is foreign matter on the guide rail
|Clean the guide rail with machine oil
|Blocked knife tip
|Clear off the foreign matter
6. The material is not driven correctly or there is abnormal noise when the machine is running.
|The material is jammed
|Check for abnormal material which makes the material jammed
|Wrong location of the pinch roller
|Check and adjust the location of the pinch roller
|Worn or damaged rubber of the wheel
|Replace the rubber
7. Machine can not receive the command from the host computer.
|Error of USB driver
|The off-line key might be pressed by some object
|Remove the possible object that might hit the off-line key
|Origin isn’t set up after off-line
|Press the origin key
|Baud rate setup error
|Transmission rate is 9600
|Streaming control setup Error
