Although testing while attached to the benchtop worked initially, we knew eventually we'd need a real bed. Today we made some more progressing in finalizing one. I am very happy with the rigidity of the machine, it is pretty bombproof in this config. Getting some 3/4MDF for the bed which will then have 1/8" galvanized steel on top for a firm surface to magnetically attach board holders, strip feeders, trays, etc in whatever config I need. Left plenty of extrusion exposed all the way around to attach feeders we well.
