Common problem of laser engraving machine have?

Takeaway: laser engraving machine excitation bald head out the possibility of the main light, common problems of laser switch did not open. With laser switch button on the panel, press down to open, pop-up to close. The light path. In the light path slants the magnitude of the larger case also can appear such problem ( The light slants to the lens outside) 。 About the adjustment of the light path has talked about before, in the not much said, adjust to the interpretation of in front of the reference. Press operation panel test observation ammeter status: no current: check whether the laser power supply is switched on, the high tension line is loose or fall off, signal wire is loose; There are current: check whether the lens is broken, the light path is serious deviation. Check whether the water circulation system is not normal drainage systems: check whether the water cooling machine is no electricity or damage; Water: check whether the water inlet and outlet or a water pipe burst. Able to some introspection, sending data don't shine, Check the computer Settings is correct) Damage of laser power: to the laser power supply, and see if the fan run normally, if not normal operation, the laser power supply problems. This is just need a change of power supply. Whether to provide signal detection, first MPC6535 interface card, at the time of continuous make laser light, use multimeter ( The positive on the high level input signal of the multimeter on one foot, the cathode on 4 feet on the ground) , test the high level input signal is 1 foot and laser control signal 3 feet, take a look at the voltage on the multimeter, if the voltage is far less than 3 v, the MPC6535 boards cannot provide the signal. Above if no problem, can detect the water line, take 3 feet and 4 feet short, open and see if there is a laser output ( Now open the laser, must open the water-cooled machine, to laser tube cooling, otherwise it will damage the laser tube) Signal lines, and if so, then water-cooled machine has a problem, check whether the water line can have poor contact. If none of the above problems, and then check whether laser cable socket under the good contact. The definition of the power cable of each Angle: ( A common power supply more than 100 w laser tube) 1 feet for 5 v output power, the output current of 20 ma; 2 feet for H ( TH) The input signal, the switch control of light, the high level ( 3 v) When the light, low level ( 0. 3 v) When no light; Three feet of L ( TL） The input signal, the switch control of light, the high level ( 3 v) When the light, low level ( 0. 3 v) When no light; Four feet of P ( WP） The input signal, the switch control of light, the high level ( 3 v) When the light, low level ( 0. 3 v) When no light; 5 feet to G signal, this Angle must be connected to laser machine chassis panel, in the land of; 6 foot as IN the input signal, the control end of the laser power, can be 0 5 v analog signal control, also can use 5 v for the amplitude of the PWM signal control; Whether to provide signal detection, first MPC6535 interface card, at the time of continuous make laser light, use multimeter ( The positive on the high level input signal of the multimeter 2 feet, and negative in 5 feet on the ground) , test the high level input signal is 2 feet and laser control signal 4 feet, take a look at the voltage on the multimeter, if the voltage is far less than 3 v, the MPC6535 boards cannot provide the signal. Above if no problem, can detect the water line, take 4 feet and five feet short, open and see if there is a laser output ( Now open the laser, must open the water-cooled machine, to laser tube cooling, otherwise it will damage the laser tube) Signal lines, and if so, then water-cooled machine has a problem, check whether the water line can have poor contact. If none of the above problems, and then check whether laser cable socket under the good contact.
