On this page we post pictures on machines
people built based on our design with their improvements
Here is a design based on the Foamlinx FC2912.
This is a low cost version of it - with a turn-key solution under $900 (computer
and software not included)
For more information please visit www.rcfoamcutter.com
if you are interested in sharing your information, please send us pictures of
your machine and we will
post them here.
Machine built by Vern - Notice the XPS pink
foam in the back made by Owens Corning
XPS Foam - the pink stuff
A great idea low cost coupling
Motor coupler
Nice cut !!
Stepper motor driver board with a fan
Some more great ideas from Vern -
Stepper motor driver with heat sinks
Motor coupler
Linear slide
Machine built by Rick Hallett

Cutter made by Ron Kruse
Nice surfboards in the background - are they made out of EPS foam or
Polyurethane ?
Some picture from people who purchased our new machines

A FC2913 automatic CNC hot wire foam cutter machine in Taiwan
Some very nice improvements done on our machines (thanks !!!)

Hot wire foam cutter cutting Coroplast
Another great idea: a simple tensioning mechanism - the
springs weight does not effect the actual cut.
Reduces wire vibration
Machine that Andrew Donatelli built
Stepper motor driver (old version) made by 8Linx
Motor coupler
Here is an XY plotter/cutter based
on the linear slides used in the foam cutter
In the future we plan to mount Laser Cutter
Notice the new stepper motor driver which can support up to 4 unipolar motors.
It is designed to work with most CNC software. The one shown above is from www.kellyware.com
Same table with a Dremil mounted -
Notice that the Dremil Z movement is not controlled by the PC (at the moment)
Over the years (about 6 years) we have moved on to larger
machine. As shown in the pictures below
This machine which we custom made for a customer can hold up to 7 hot wires and
will cut two
block as once. The machine is 8' x 5' x 10' (X, Y, Wire length).
The Drive mechanism is a bit different then in all the other
machines. In this machine we used a chain
to drive the X axis. The use of a chain will enable us to have a X axis as long
as we want.
With a lead screw or an ACME screw we would be limited to 6 to 7' and would have
to go a
lager diameter of a lead screw in order to overcome the wobbling and the
vibration caused by the
long lead screw.
