K40 Repair - No output to mirrors - Laser tube cut a hole in water hose near tube?
I got a strange one here I would appreciate if anyone could chime in if they seen something like this or have a idea what to look for to find the exact problem to repair.
My k40 has worked for a year fine since I got it. I use it sparingly but never had a issue. I have a water pump going to a chiller that has always worked fine. Started working on something a few days ago, and I cut for 20 minutes without trouble. Then I noticed the last cutting out mid cut and I was looking for a issue. I was checking water flow and it did seem like one hose may of been slightly kinked. When I unkinked it and got full flow back water outlet stream was very hot, so I thought maybe the tube overheated. I left it off for awhile giving it time to cool. Made sure water flow was good and cool before trying again and I could not get any output from my laser on the material and immediately had water everywhere. I quickly powered all down and found that some how the tube, in the back housing, cut a hole through the water hose. Very strange to me, but I could see the laser tube was not outputting through the tube now and just lighting up at the beginning of the laser.
After cleaning, drying, and replacing house I tried the laser a few more times on very low settings and I have no output to material, but almost instantly I had a new pinhole size hole in the new hose next to the tube in the back. So somehow at least a partial laser must be coming out of the side of my tube hitting the waterline next to it. Very strange so I wanted to see if anyone has seen something like this, and if my tube is fried or if their is a possible cause I could look for.
