yes, the xcarve was nice but took up a big corner of my garage and honestly I wasn't cutting stuff near 1m x 1m and the ~400 x 400mm of the 4040 pro is more reasonable. It's stable (rigid) but not extremely so. You will not be able to make cuts as deep as you want, and aluminum will be challenging. But it's great for carving up a hunk of figured maple into art, as well as many other workflows.

There are things like the MPCNC ,and building your own design with OpenBuilds, but I don't recommend them unless designing, building, and maintaining is what you want to spend your time doing.
