Flashing in laser tube

I’ve never seen it before, so I’m not sure what is causing it, but I am seeing flashes in my laser tube as the laser is cutting. What should I do to fix it?

When it’s not running a job?

This is during an engrave. But I’ve never actually seen the laser tube light up when engraving or cutting.

Let support take a look at it…but there’s usually a little purple flashy light happening at the ends when a job runs. Maybe if the tube is dirty it would reflect along the length.

That’s the actual laser beam at I’m guessing full power?

I have watched mine for years, and that looks like normal operation during a cut or full power engrave. I’ll bet that now that you have noticed it, you can’t un-see it! :no_mouth:

Support will probably have a look at your logs to be sure.

Completely normal at a high power. It’s hard to see at low power but still happens.

Hello @zoramite,
