I am resolve one problem with laser tube and after half hour I have new problem. Laser working on press test button but when start engraving( or cutting) no laser. I think that I have problem with pressure switch.
That part is connected with one "T" piece on water cooling pipe! When I start cooling laser, normally I heard "click" on that side on machine but now nothing? I try press manually switch but that is very hard - I don't know is it normally or not.
that part looks like :

Or is it possible that cooling system (and pump inside) do not working correct.
Or....
You can see how problem start ,I am engraving some bottles and see after 1 hour working, that part in other two picture is my part , and I think that is problem but...
IDEA ???
ASAP !?
