I have a 50W blue/gray with Ruida controller and Lightburn. Everything worked great right out of the box but now I have developed an issue I can’t resolve myself.
When I send a cut or engrave to the laser the mA meter is registering only about 5mA regardless of percentage I set either in the controller or in Lightburn. Is this the start of a power supply issue or is there something else I am missing? Tube is purple and has less than 20 hours on it.
Pulse gives full power - i.e. 60% on the controller and I am getting 19mA.
