I tried Lightburn with my laser 50W (RDC644XG) the laser head moves but the laser beam does not light up.
Could be anything. If you want to know if it is LightBurn then attach the file. It may be something as simple as the power settings.
I have two of these controllers that I test with regularly, so I’m going to have to wholeheartedly disagree with you. In fact, the 6442G was the first controller LightBurn supported.
As Joseph suggests, you likely have a setting wrong. Min Power being set too low for your machine would be my first guess.
I can also vouch that Lightburn works. I just installed an RDC6445G and have no issues. For my 90W tube 12% is about the minimum it will fire at.
Is this a new setup?
