Gantry style CNC mill

the machine:

Hi,

I am sure it's going to be a nice machine but based on my experience I'd suggest making some changes before it's too late.

My frame was originally similar to yours but I had to remove those wheels because of shaking caused by the G-forces. A fast machine with heavy gantry and Z movements will generate far too much shaking even if all the four wheels are locked. I changed my design, moved the wheels and the machine is now lowered to the floor on four wooden blocks, efficiently reducing vibrations and shaking. The wheels are still there but they don't touch the floor and gets lowered when the machine needs to be moved.

I assume your machine is going to be much faster than mine, considering you are using servos, so it would be a shame if you had to lower the speed and acceleration just to prevent the violent shake, so consider this before it is too late.
