Question

CNC foam cutting machines


Got a few projects coming up that will require the use of a CN hot wire foam cutting machine. A quick search shows there's several types available, I was hoping for some recommendations.
Something that can cut tapered wing sections at a minimum, maybe one with another axis to it can do round objects.

Any suggestions please?

Here's a design thattakes inspiration from the DIY 3D printers universe (in fact most of the parts are 3D printed). It's designed to be modular and the drive system ensures a very good price - precision ratio.

I built this foam cutter using drawer slides and threaded rods: https://www.rcgroups.com/forums/show....php?t=1667186

Works very well.

There are a few builds here. Here is mine. https://www.rcgroups.com/forums/show...ht=foam+cutter
Movable towers are good because you can set them close to the wing span you are going to cut.

I might sell my new one.

My interest has gone elsewhere and I'm not interested in matching wages with Chinese workers.

Getting interested in doing this again.
Anyone know much about the machine on the lower half of this page? - http://www.rcfoamcutter.com/full.htm

They all seem fairly expensive for what you get. Just longer screw-jacks, etc, but the price goes waaay up.


Edit - Or any links to a complete kit?

And you can get here a good Usb controller: http://www.ideegeniali.it/shop/152-cobrausb.html

You can drive it with the freeware Theremino Cnc application or with my commercial devCnc Foam: http://www.devcad.com/eng/devcncfoam.asp
