![]() ![]() 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). ![]()
