what is the most practical yet technically optimal suggestion for the base of the machine, the table or structure that the MPCNC will rest on? MDF, plywood, a timber frame, aluminium extruded profile frame, … ?
Of course, it depends, as always, on the demands and goals. This ranges, in my case, from 2D-milling of MDF, PVC, various woods and alumimium, 3D from polyurethane foam to wood, and moreover a somewhat open construction to also make mortises and tenons. 4D milling not excluded for the future.
I’ve seen many examples of your working machines, what would you reommend as an optimal solution, if there is any? Also keeping in mind that the leveling should be easy, and that a sacrificial board should be easily placed and replaced. -
Side-requests: The machine should be mobile, yet have a solid standing, maybe even stowable in an upright position. Oh yes, I opted for a 20" by 30" size.
Sorry for my non-native English terminology!
Thanks and cheers!
