I operate a small making business out of Tampa, FL. I normally operate a 100W Chinese laser but a couple weeks ago it stopped mid-cut and I turned it off and then on, it came on for a few seconds, then flittered off again. I opened it up to find one of the nodes had melted away the shrink wrap and it had actually melted through the power switch.
I was able to find and replace the power switch but that didn’t work. I read some FAQs and it seemed like the next option was to replace the 24V power supply but that didn’t seem to help. I’m not getting the LED on the 24V power supply to light up at all on either supply. I’m a maker, not an electrician, so my knowledge on electrical systems is minimal. My next step is to either replace the main board/controller but that’s going to cost several hundred dollars.
I’m 3 weeks behind on my orders of covid facemasks because I can’t get my laser to work to cut the leather and it’s really hurting me. Can anyone offer some advice or troubleshooting steps so I can more accurately track what is actually wrong? I only have a pen tool that detects electricty (getting a multimeter tomorrow) but I can trace that when I turn on the switch and the various buttons that electricity is being delivered to the various items. I can tell for instance power is being delivered to the 24V power supply but there is no power coming out of it. The little green output LED doesn’t light up at all which leads me to believe the problem may be the controller since that’s where the 24V output goes directly to but I’m hoping I can confirm that before I go and spend $400+ on a repair that may or may not work.
Any help that you can offer would be greatly appreciated!
