#Deskcnc tutorial softwareKCAM - same as above - generic CNC router software - will do nice PCB boards as well 5. Mach3 is a generic CNC router software will work with the package below, but you need to be able to generate 4 axis g code. GMFC - needs a timer module - without the timer the package below will not work 3. FoamWorks software will work with the electronics in the package below - has CAD capabilities as well 2. The following can be found in the drawer section, you will need two 16" drawer slides The Home Depot Catalog number for 24" slides made by Liberty 7-81266-18070-4 There are a few software out there that will run the machine - some need special hardware - we spent months testing and evaluating many of these software and hardware. Any vibration of the posts will result in vibrations on the wire resulting in "waves" or not smooth cut of the foam. The posts can be found at the fence section at Home Depot You can replace these posts by any other post as long as you are able to keep them from vibrating during the cut. If building a hot wire CNC foam cutter for props, crowns, moldings You would probably want to go with a 4' x 4' (X x Y) EPS Foam billets are usually 3' x 4' x 8' or 4' x 4' x 8' XPS foam comes in sheets of about 4' x 8' x (1" or 2" or 3" thick) If building a CNC foam cutter to cut Polyurethane foam - FORGET IT Polyurethane foam should not be cut with hot wire, but a blade or a saw There are CNC foam cutters for Polyurethane that work similar to a band saw But use a abrasive wire instead of a saw - click here for more information In this section we will build the two Y posts or towers (Y axis). We started out building a machine to cut wing cores, but soon after we discovered a huge interest in the machine for other industries - like moldings, architectures, surfboards, Logos, props, packaging Willow Sills, Casings, Wainscoat, Fascia, Crown, Parapets, Wallcaps, Pediments, Quatrefoils, Columns If you are building the CNC foam cutter for RC wings, then you would probably need 10" max travel on the Y towers. Some surfboards are up to 12 feet in length, the only way to cut these boards would be a belt driven or chain driven mechanism I will try to cover this topic in the future with a sample machine and pictures. An example of a machine larger then 8 foot would be a surfboard foam cutter. Belt driven machines are usually 8' and longer but require the use of micro-stepping. Another way is to move to a chain or belt driven design. One way to overcome this problem is to move to a larger diameter lead screw. The problem with a long lead screw is that because it its own mass, it will "wobble" in higher speeds. Keep in mind that for longer travel you will need a longer lead screw. The design can be modified to almost any size. The first prototype was made out of wood, but didn't look "professional" enough, so I decided to go with a more robust design made of steel. Most parts can be found in your local hardware store, like Home Depot.
