Smoothieware

Smoothieware is working with LW4 but not recommended for fast raster engraving, as they don't support a decent streaming protocol with real time control!
Consider installing grbl-LPC on your smoothie compatible board for real fast raster engraving.

If you still want to use Smoothieware, you must install the latest firmware-cnc! Please check https://github.com/Smoothieware/Smoothieware/tree/edge/FirmwareBin for download and installation instructions.
