I have a CO2 laser that has to be water cooled. I have a setup with a water tank then it goes through an aquarium water chiller then through the laser tube. It works great but it’s upstairs in the house.
I looked at those spindles but I’m going to put the xcarve in the garage / wood shop and it get’s below freezing here.
The garage is insulated and I do have a natural gas heater in there but I don’t want to run it all the time just to keep my spindle from freezing.
If I lived in a warmer climate, I would go with the water cooled spindle also.
