Congratulations on entering the great CNC hobby!
Most everybody on this forum has built some type of workbench for their X-Carve, from a basic table with 4 legs to a full cabinet to hold all the accessories with the X-Carve on top.
A lot of people have built a torsion tops for the bench
Others use a couple pieces of 3/4 plywood or even MDF.
Here is a good place to start looking at what other X-Carvers have built
If you have any questions during assembly or use of your X-Carve please feel free to ask the forum, I think you will find lots of knowledgeable people here that are able to help.
