I was running a job like I always do and then laser stopped halfway through. I have my water chiller running and air assist on. I tried to pulse the laser through the controller HMI and it wouldn’t fire. So I pulled the side panel and tried to pulse the laser with the test button and that wouldn’t fire either. The power supply makes a sporadic electrical arcing type noise although it is faint.
This is a 50w chinese ebay machine. Blue and white. It has 364 hours of job operating time and 150 hours of ‘laser on’ time. Tube is old as it sat in an air conditioned house for a few years before I started using it.
Should I replace the tube and the power supply? Or is there another avenue I should be looking for an error. No connection problems with the computer and the HMI seems to be behaving normally.
