Hello everyone,
do anyone know if mounting one of those chinese CO2 laser tube in a vertical position could be an issue? Would the water flow be OK?
I am in need of engraving a large panel so I want to mount the mirrors and the tube on my CNC machine and I was thinkin to put it underneath the machine and pointing it upwards, but I am concerned about the water flow since I never saw one of those tubes mounted like that.
anyone tried that?

Thanks for your help
