Laser not getting power
Posted: Mon Apr 18, 2022 6:24 am
I was cutting a sheet of acrylic last week and towards the end the laser kept powering on and off about every second, the meter would go from 30 to zero and back so I powered it off and restarted it. Finished the job and it worked fine the next day, Two days later I was trying to cut 8 acrylic sheets and after completing 5 of them the laser would not come on, even after restarts.
I did some troubleshooting over the weekend and here is what I know works - power strip to the plug is OK, power cords from strip to back of machine are good and working, Two new fuses, two new rocker switches (I've had the rockers go bad before). The controller rocker switch works fine and lights up when on, the menu is not reporting any errors, and the machine starts up normally.
The rocker switch for the laser doesn't light up when switched on and there is no power to the tube. I pulled the leads off the tube and reset them and added lots of silicone for insulation. The refrigeration unit is running as normal, water and air are as normal.
If the laser rocker switch doesn't light up is there something it goes to that might have burned out or have a bad connection? I'm pretty sure I have the new rocker wired up the same, but I got the controller switch wired up wrong before. I have more fuses so I could test that.
Any ideas as to what might be the problem so I can look at it?
