Description

4 Axis DIY Hot wire CNC for RC Hobbyists, Aeromodellers and Designers.

Did you ever wonder, if you could convert thermocol, styrofoam, EPS, EPO, XPS foam available as packaging , or insulation, or in form of blocks or sheets into beautiful RC airplane wings ?

Or cut that custom airfoil that gives the best glide time for your college project ?

Or cut foam cores that could be used for Vacuum bagging and build that extra neat UAV Carbon fiber wing.

Or be a star amongst your local flying club to give out custom airfoils to fellow friends and fliers .

All electronics and hardware included. Only required is a computer with a parallel port running Windows 7/XP 32 Bit.

FAQs:

1. What is a 4 Axis Hot Wire CNC and what can it be used for ?

A Hot wire CNC uses a hot wire to cut foam, andthe wire is driven using stepper motors, which are driven by a computer.

End result ? You can cut any airfoil, or design, precisely and accurately. Does not require any templates, and the speed of the wire is maintained constant by the computer to the panels cut are absolutely professional.

2. Why so less, when other similar kits comes 4 times as much ?

Because, we have used many smart/innovative ways to reduce the costs:

-We have used mass produced drawer slides instead of expensive linear guides and rails ( which costs 10x as much.

-We have used a double nut mechanism that reduces the play and backlash, and yet is many times cheaper than a ball screw.

– We have used a unique interlocking design that makes the entire frame rigid, sturdy and durable.

3. What Softwares do I need to use this machine.

You will require Mach3 Software to run this machine. This can be downloaded from the Mach3 Website. In addition you will need a software like Profilii to generate the G-Codes, OR use our upcoming library to download/generate G-Codes for popular airfoils.

4. What Computer Hardware do i need to use this machine.

You will require a Personal Computer running Windows 7/XP 32Bit with a parallel port to operate this machine. This is a requirement of Mach3 software. Consult their website for more details.

5. I am new to CNC. How do i get started ?

Welcome to the enchanting world of CNC. You will remember the day when you will cut a piece of scrap foam to cut out a beautiful airfoil.

Start by watching our build videos to see how to assemble the kit.

Then Download/install Mach3 software, and watch their tutorials to understand the application.

Configure your machine with the instructions as given in the manual

Cut out a test airfoil, using our sample GCode

6. Why 4 Axis ?

One is a X-Y Axis and the other set is a Z-A Axis. This enables you to cut tapered wings, or wings where two different airfoils are used on the same panel on each side, This gives the ultimate flexibility in hot wire cutting.

A 3 Axis hot wire cutting machine will not let you cut tapered wings,

7. What Types of foam can be cut ?

This is easy. Anything that can be cut using a hot wire, can be cut using this CNC. The temperature of the wire and speed may need to be set differently, but all types of EPS, EPO, EPP, XPS etc foam can be easily cut.

8. Whats the durability of the machine

At Vortex-RC there have been days, where we have cut huge blocks of foam continuously for 12 hours a day using this CNC. Its has been two years since we have been using this CNC. and have cut over 500 panels, and hundreds of sheets using this CNC. If built and operated correctly, your CNC will cut thousands of airfoils easily.

9. Drawer Slides, threaded rods and a wooden frame ? Are these accurate enough ?

A Hot wire CNC is different from regular router/milling CNC. In a hot wire CNC, the wire does not touch the foam , and the foam is cut using the radiant heat of the wire. What this means is that during the cutting process there is wire little mechanical load on the frame of the machine. On the other hand a router/mill drags the bit across the part, wherein a lot of mechanical rigidity is required, which justifies use of mild steel, aluminium , cast iron frames.

To reduce the backlash in a threaded rod, we have used a double nut design. This nearly reduces all of the backlash/slop from the assembly.
