Power lost laser output

I hope anyone can help me.
The output of my laser lost his power after switching to Whisper. I know it is not related, but does anyone how to check or a solution? Also I changed to a new tube, but still to little power output.


there is a Test button on your laser power supply(LPS), see if you get full power out of your laser when you press that button. If you do, then your LPS and laser tube setup are fine and the problem might be in the control side of things( controller or software ).

PS, it is generally a good idea not to change a bunch of stuff all at once unless you are an expert at all parts being replaced. By expert I mean knowing and understand the inner workings of all changed items and anything else in the path along with their failure modes.
