Smoothieware

Smoothieware is working with LW4 but if fast raster engraving is important for you, we recommend replacing Smoothieware with grbl-LPC (https://github.com/cprezzi/grbl-LPC) which also runs on the LPC1769 based boards and performs much faster for laser raster applications..

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.
