Hello
I have been using co2 lasers for years now, I think my newest one is my forth. I have been able to problem solve most of my issues but have come across one that stumps me.

I did a run on engraving with the laser, and all was fine, but when I went to do the next batch of engraving it had no power. My tube had been losing a bit of power for awhile so I thought it was just done, so i replaced the tube. No power still. Replaced power supply still no go. I am using a
RDC644G-B (EC) controller and i see that I have a red light on 15 (GND) with 14 flashing. I have checked all my connections so I have no idea what I need to try next.
