      Narbara -- I d say that may be problematic....unless he s using offset??? Oopsy, very neat machine though....would love to have one of those to play with.

          The answer is that this block in beech-wood was only a test on speeds,
          etc... to learn what the possibilities and limitations are of the beech-wood
          and to check the design and translation of every letter through the
          3-dimensional CNC software and how every letter survives the routing.

            Erik,
            Thank you for posting that video. Do you use the v-bit for all
            your cutting or do you start with end mills? Also what programs are
            you using? I have a friend that makes brass dies for foil printing
            and he uses ArtCAM. I've watched him program images and text a number
            of times and it seemed fairly simple. The cost of ArtCAM of course is
            a problem.
            I just acquired a piece of Corian after hearing from another
            artist that it prints well. Other than its cost it seems to be the
            perfect candidate since it's designed to be machinable. Here in North
            America it's only sold to authorized fabricators who don't normally
            sell it in sheet form. A laminate of 6mm Corian and MDF planed to
            type high could be the perfect match combined with CNC technology, no
            variation in qualities or grain to worry about. I see on Wikipedia
            that Corian has several competitors, who I'm guessing may be cheaper.
            I'm also experimenting with 3mm white styrene sheet laminated to MDF
            which is considerably less expensive.
            Keep us posted on your progress and thank you for the pictures and
            video, they have inspired me!

                Brian,

                I normally start with an end mill which works only in X & Y on a depth of
                for example 5mm and this one takes away most material and does first the
                rough work. In the last finishing step I use a 60 degree V-bits for all the
                edges and fine details and this one goes three dimensional X, Y & Z because
                you need the fragile sharp top of the V-bit to cut out the sharp edges and
                small details. I use several softwares including signmaking software very
                similar to ArtCam to finally come to a WinPC-NC file on which this
                CNC-router runs.

                Buying large panels of new Corian is indeed a problem but some authorized
                fabricators are selling their scrap on eBay at reduced prices and some less
                popular colors can go really cheap. In Europe there are some companies where
                you can order cut to size panels in all the different colors but this is
                still expensive. Another possibility could be 1 ¼" thick PVC which is used
                as a replacement for wood like this AZEK To Mill (ATM) which is made in
                sheet sizes of 4 ft x 8 ft:
                http://www.azek.com/viewProduct.php?id=12
                I don't know this ATM material here in Europe and haven't tested it but it
                looks interesting at first sight and is probably cheaper than Corian.

                Regards,
                Erik

                    themselves I think.

                    Erik, I was excited to see your post about this new material that was thick enough to be planed down to type high. The website showed what appeared to be a

                      Erik,
                      I was excited to see your post about this new material that was
                      thick enough to be planed down to type high. The website showed what
                      appeared to be a solid dense plastic, so I quickly found the
                      distributor and then a store that sold the product, but unfortunately
                      it's not suitable for printing. It's most common use is as a
                      replacement for lumber to make decks, one side is smooth while the
                      other side has a faux wood grain finish, however even the smooth side
                      is covered with very fine pits. It appears as though it's a mixture
                      of plastic and sawdust or some kind of filler to reduce costs, but it
                      was worth a try!

                        http://en.wikipedia.org/wiki/Polyoxymethylene

                        check out the part about machining.

                        It may be on the pricey side for large sheets though.
