Hot Wire CNC Foam Cutter Parts List

posted in: Products | 6

This list includes the parts required to build the USB or the Parallel Port versions of the CNC foam cutter. The USB version is my latest build and will be about 30% cheaper than the older parallel port version. Using the older parallel port version is probably the simplest and cheapest way to use Mach3 or LinuxCNC.

All the parts in a convenient PDF with clickable links

I haven’t included any eBay links because they go out of date too quickly but it’s worth a look.

As well as Amazon and AliExpress have some good deals, shipping can sometimes take a while and make sure you check the total price including that. Here’s the main CNC page for controllers and steppers http://s.click.aliexpress.com/e/bfoSYeqU

The eBook and videos have step by step instructions on how to build your own CNC foam cutter. There is a small charge for the plans.

Parallel Port Version

If you decide to build the parallel port version then use one of the controllers below. The NEMA17’s listed above can still be used. If you are building a larger machine then the NEMA23’s listed below may be a better choice

    Hi Keith,
    Would use the DevWing Foam ver2 or the DevCnc Foam 1, confused as to which option would serve to cut wings only.
    Regards,
    Mike

      Hi Mike
      Dev Wing Foam is the right application to cut wings. DevCNC Foam is the software that controls the foam cutter. It does the same job as the “Hot Wire CNC Controller” I use but it probably has a few more bells and whistle.
      Hope that helps

    Hi Keith
    Can’w insert a 5’th rotary axis to this good build , also can’w expand thé X and Y axis a bit more ?
    Thks and congratulations.

      Hi Said
      The firmware won’t support a 5’th axis. There is a 5 axis GRBL firmware but I haven’t tried that but then you would need a different controller software as well. Using Mach3 or LinuxCNC with TB6560 or TB6600 based controller may be a better option.
      The X and Y axis can be expanded as required but as you get bigger and heavier the NEMA17 may not have enough power. You would probably need NEMA23 which the RAMPS board and drivers are not really designed for, NEMA23 usually need a lot more current.
      Thanks for your kind comments

    Hello Keith,

    Drawer slides are 450/600mm full length or closed length ? 100% extension ?

    Best wishes,
    James

      Hi James
      It’s the closed length and 100% extension. I’ve only once or twice had them more than 60% extended. Using the closed length means the slides are better supported. If you used 600mm fully extended slides then it’s not as well supported but would probably still be OK.
      On swept wings, I rotate the wing to save foam and the slides don’t have to move as far out, I have a video here explaining it, Swept Wings

      Hope that helps
      Keith
