![]() What makes a hot wire CNC cutter particularly accurate is that the foam is cut using a hot wire that can move vertically, horizontally, and at various angles that flawlessly remove the unwanted foam with incredible precision. Hot wire CNC cutters are controlled by computer programs that can accurately replicate the shapes and design of the model uploaded to the software. These days, CNC wire foam cutters are able to design and make these increasingly complicated designs come to life. The machining industry is constantly evolving to keep up with the creativity and needs of its clients. If you are looking for custom-cut foam fabrication then look no further than PFI Advanced Equipment Manufacturing. Thus, the ability to transform these raw materials – whether it’s plastic metal or foam – can be affected by the quality and caliber of the equipment used to cut, shape, bend or manipulate the raw materials. On the face of it Foamworks and CADWorks for <$100 the pair looks the cheaper option and will get you working faster from DXF files.but if you ever want to build a non-foam CNC machine you'll need MACH3 later.In the machining industry, the key to success is being able to make unique, customizable parts or pieces from raw materials that are individually designed to serve a specific purpose in the manufactured product. However knowing G-code isnt essential if you are going from CAD/DXF via a CAM package. On the other hand, MACH3 allows manual input of simple G-code as its human readable, whereas DAT looks less suitable for that. The difference is that while CADworks simply has to convert DXF to DAT for an essentially zero width cutter, DXF to G-code generally requires complex calculation to work out the offsets for varying tool diameters and to deal with complex z-axis movement for pockets and raised sections (not really appropriate for hot-wire). ![]() To get to G-code from DXF requires a CAM program, and there are many available but there are few good cheap ones. ![]() Mach3 is more expensive and its input data format is G-code, but its free without limitation for small project files of <500 lines of G-code. Its main limitation would appear to be that natively it can only cut wing sections as its input data format for other shapes is a DAT file which needs their CADWorks product (also $49) to convert DXF files from standard drawing packages.įoamworks is in some ways simpler than Mach3, mainly because hotwire doesnt need the same control complexity as a rotating cutter. Foamworks is a proprietary CNC control software (but cheap at $49) which controls a CNC hotwire cutter (up to 4 axis). ![]()
