K40 not firing with the test button - Lasers - Maker Forums

Good morning all, first time poster here. I’m having some troubles with my k40 laser cutter. Long story short: it will not fire the laser on either the test switch button or the button on the power supply. I contacted Vevor, who sold it to me, and they very kindly sent out a new power supply and laser tube for me under warranty on the assumption that it would be one of these two items that was faulty, but I am still without a laser. There is also no sign of life in the analogue current indicato
