I need some help here. I was doing some test on a bottle and suddenly the laser start to act funny, not engraving continuously, then is stopped fireing.
See the attached images and videos.
The power supply looks alright inside but the power led flashes.
The tube is about 3-4 months old but i didn’t used it to much.
PSU, TUBE? …I will change the water today to take one off the list
