Over the last few days, I built a CoreXZ machine based on the Voron Switchwire.

I chose a CoreXZ design because I want to place most parts of the machine underwater for noise and fume reduction. The motors that I'm using are IP65 rated. So they are safe from water splashing and condensation, but can also not be permanently placed underwater. By using the CoreXZ design I can place the motors at the top of the machine to keep them out of the water. Another reason for choosing this design is the L shape of standard handheld plasma torches. By mounting the torch in a vertical orientation with the grip pointing to the top and by moving the torch in the X and Z direction, the torch does not reach outside the machine dimensions in the X (and Y) axis and so the water container has to be only large enough to fit the machine into it.

For now, I'm using two 90l buckets stacked on top of each other.

Cutting takes place underwater, so the hot metal particles from cutting should cool down very fast before they can damage the plastic bucket. I will still keep an eye on it and maybe build a metal inlet for protection.
