Here are some pictures of my build. I’m using LinuxCNC with a Mesa 7i96 and THCAD for internal THC. The water pans are made of aluminum. The computer is a Dell Optiplex 790. I have a latency error every once in a while so I’m not sure if it is well suited for CNC or if I just don’t have my settings quite right. I cut the cabinet out on the table itself. woohoo reprap!
I wish I would have made the tubing that the skate wheels ride on higher. The water tends to spray everywhere while cutting and I’m worried about it ruining the motors. The water gets. Really dirty and that splashes onto the tubes and threads.
Even though it’s not perfect I’ve been able to get a lot done.
The guys at the linuxcnc forums might be able to help you with your latency issues. There’s all kinds of tweaks you can make in the bios and kernel boot options and crap I have no clue about. I found I had to remove the pci wifi card to get decent latency.
How deep is your water pan? How much water do you usually put in it? Is any smoke or metal dust still escaping into the air? I haven’t made my pan yet but I get the impression there’s optimal levels to minimize splashing.
