check laser engraver tube whether working.

do you have laser cutter engraver machine,if you have,and face some problem in laser tube,so you need to check whether the laser tube problem, how to check it, and follows information can help you know.

how to test the laser tube whether is ok working or damaged.

There maybe three reasons made the machine don’t work normally

1.Short circuit Pand G port of the Laser power.

2.If the first step not work, check the wire between laser power and laser tube, whether there is any broken

3.If still not work, press “Laser” key and connect the positive clip of the laser tube to the machine case. If there is sparks, the laser power is well, if no sparks, the laser power may get broken. 

also follows are laser engraver other maintain.

1 linear guide rail filling oil : Laser engraving machine used for some time , engraving, cutting smoke , dust, corrosive effect on the rails , so regular maintenance guide . Turn off the power of the laser engraving machine , with a clean soft cloth clean the rails , then drops on the rail on the oil, finished oil on rail rolling back and forth to let slide in it, make sure that oil from entering the block . On completion of the first fixed oil do not let slide rail rolling back and forth in it, then loaded on rail must first times , pay attention to the rail when installed , should all staples installed, maintained level with the slider at the belt fixed , then the lens installed , dimming about X whereabouts path is completed.

2 Focus Lens Wipe mirrors : laser engraving machine | Laser cutting machine after a period of use , smoke dust will adhere to the surface of the lens , the impact of carving, cutting depth , will also affect the engraving, cutting precision. Usually in about a week ( based on laser cutting machine | engraving machine uses frequency ) with anhydrous alcohol to three mirrors , a focusing mirror carefully wipe clean.

3 bearing oil : laser cutting machine uses a lot of bearing , in order to ensure good cutting, carving effect , some bearings require regular refueling ( except oil- bearing ) , with a clean soft cloth to wipe the surface dust on the bearings , using a needle to oil suction needle , then slowly injected with a needle bearing , while slowly rotating bearing grease can .

4 belt ( belt ) slack adjuster : laser cutting machine belt drive system has a number of articles , if the timing belt is too loose , it will appear engraving fonts ghosting , if the timing belt too tight will cause belt wear . After a period of time , adjust the belt tensioning screw , adjust the belt to the proper tension , engraving text does not appear ghosting, and laser engraving machine , laser cutting machine is running low noise is appropriate, or consult the manufacturer's technical staff.

Maintenance of the laser tube 5 : Laser engraving machine laser tube using circulating water is cooled down to long-term use , there exists some white tube scale , we can add a small amount of vinegar in the circulating water , in addition to the inner tube ditch off , then use clean water to wash and clean the laser tube inner loop , so the laser tube will be in the best working condition , life will be extended.
