I've built the box, using aluminum box corners and poly-skinned foam board. It's heavy, but should work ok. I haven't finished it yet, but the Y-Axis Servo/Wheel will project though the bottom of the front - mostly to save volume. I can get at the Z-axis and X-axis wheels with the front of the cabinet open. So the question is mounting the bed of the mill. I plan to use a misting coolant system. The base will be plywood with coating yet to be determined. I think I read that someone else had supported his mill on stand-offs to get the bed off the bottom of his cabinet maybe so it wouldn't sit in moist coolant. Obviously making little one inch high pads at each of the mounting holes would do the job. I'm assuming that this won't distort the bed and that there isn't any other downside of doing this that I haven't thought of. What do you think?
