Metal and nonmetal laser cutting machine no light solution
Metal and nonmetal laser cutting machine no light solution as follows:
1, Check whether the water cycle normal, let the water normal cycle, If flow protection is broken, you can use short water protection;
2, Point presetting, see whether the ammeter swing, if not swing, measured with a multimeter 220v into the laser power, supply has electricity but still no light, maybe power failure may need to be replaced;
3, Use ground GND ground line and water protection test weather water protection is bad, the + 5v and AIN shorting check output maximum power, if have light is potentiometer is broken, need replacement.
4, If walking program no light , online cards can be measured with a multimeter test 15 (H) or 16 (L) angle and the 14 corners have more than 3v DC voltage, if so, the card is normal, there is no possible card has the signal problem;
5, There have sound in power supply, usually the power connector is bad, re-welding or connection, then blown the dust inside the power supply.
