Another Cad tool software is DevFoam, that combines both the drawing and the G-Code generation. More recommended ones include Instant Engineer 14, which can be purchased online for few dollars, DesignCAD, AutoCAD and TurboCAD. There are various CAD files in the market. It is a modeling tool used to design curves and figures in 2 dimensional space (2D) or curves, surfaces and objects in three-dimensional space (3D). Running the machine with the software to execute the desired shape.Īny Cad tool, such as Auto Cad or Corel Draw can be used for drawing the shape, as long as the file can be saved in a DXF format. The towers can move in an X-Axis (right-left) and a Y-Axis (up-down).Ĭutting the foam is done in 3 basic steps:ģ. The machine consists of a wire running between 2 towers, which is heated via hot wire power supply, thus melting and China cutting the foam into the desired shape. Maybe they'd put a system with this together for you.What Software to Use When Operating a CNC Hot Wire Foam Cutting Machine?Ī CNC hot wire foam cutter is a computer controlled machine used for mainly China cutting Polystyrene foam (also known as EPS foam) and similar materials, such as polypropylene (Known as EPP) and polyethylene (known as PE). DESKCNC CONTROLLER CODEIs this because the controller takes G code and doesn't give you step and direction access? In which case, what about this widget: I take it you don't want one of the Microproto CNC Taigs? These motors are interesting: allegedly high spec, but no proper data sheet: DESKCNC CONTROLLER DRIVERThere's plenty to consider in trying to choose optimum motors - torque and inertia, inductance and rated voltage & current along with desired speed, acceleration and driver budget. This in the UK is fine for low speed work, but really won't match any of the others for high speed stuff (the drive voltage isn't high enough to overcome the motor's inductance quickly). Gecko drives are well respected, but they're very expensive (you'd need one of these per axis ) and again they don't come with a power supply and are probably overkill unless you're going for really high torque motors. DESKCNC CONTROLLER FREEWhat's the catch? Xylotex can't export to the EU because of the RoSH regulations (they're not lead free yet, maybe the US will catch up eventually.). ![]() A great drive is under development by a guy called Kreutz on CNCzone, but it isn't a packaged unit with a power supply. Similarly the drive isn't the highest performance, but it seems competent. The motors aren't the most powerful around, but there's a trade-off: larger motors have more low-speed torque, but also more inertia, which can reduce acceleration. I've had a look around, and the simplest option seems to be the 3-axis kit from Xylotex (or 4axis if you want room for expansion) The controller takes G-code and generates all the pulses itself, thus removing the possibility of improving this crappy interface.Īlso, there's this guy who's built one in his New York apartment For example, rather than sending the signal, "pulse now", it sends the signal "pulse when your clock reaches time XXX ms" The pulses are all generated by the computer, but their precise timing is delivered by the controller. The pulses need to be delivered real-time from the computer's parallel port - in which case it needs to run DOS or realtime linuxcnc. Stepper motors have a lot of drawbacks, but would be suitable for the Mark 1 version just to get something working. There is an importer in Birmingham Motors The leading component appears to be which is also available as part of the package. ![]()
