Hi Everybody!
This morning, our laser engraver started acting peculiar and I figured I would ask the professionals for any help or advice! I have been a long time reader on this forum and really appreciate the help that all of you provide. My laser is only 4 months old from China. Has been working perfectly fine (besides the control switches burning out after the first week....). But yesterday when firing up the laser, sparks began to shoot out of the end cap on the left most side of the glass tube. We have changed the water, redid the grounding cables that go to both sides of the tube, and cleaned all of the small parts (which were covered in white/orangish dust). After doing all of this, we were able to get the laser to fire half way through the tube, but not all the way. After running for a few seconds, the flame shot out of the tube again. Have any of you had this problem? I'm wondering if it is something wrong with the power supply?
Here is a short video I took of the issue described above.

Again, thank you all so much for all of the help I've received just from reading your articles and posts, and I sincerely hope somebody else has had this problem and successfully solved it!
