K40 Stpped working,Please help to diagnose what's wrong
Hey guys
I'm quite new in lasers, for now pushing all of china sh**
I have a problem suddenly while working on project one of my laser controller board capasitors blew up , and laser went weaker and weaker till it had no beam at all.
I've fixed board, but the laser is still not responsive, amp meter does not show any life, mirrors and cooling system works fine, power supply to board and 0 to 5 V controll silgnal comes out of board. On max power I can see only small light on one end of laser tube.
My gues is that ether the tube is broken or Flyback transformer is damaged.
Could anyone help to make shure which one is dead?
P.S. power dimmer works fine. I have noticed that tube has somthing like a crack, but not shure if CO2 has leaked.
I've attached video of how laser is working.
