I'm a journeyman machinist by trade. The Ecello is a nice heavy duty machine, emphasis on the heavy! To that point, please don't put it on wheels. I know the mobility is attractive, but the mill needs to be very accurately leveled to run right. I use a master precision level, accurate to .0002" in 10". like this:

If you put it on wheels, it will twist as you move it, and you will find it impossible to get a square, parallel cut.
That mill can do a huge amount of work, and you are in for many hours of fun learning to use it!
