• If you have a Smoothieware based controller, but performance on Raster is choking you with stuttering moves: This is a known issue.
  We recommend switching to grbl-LPC which runs on LPC based boards like Smoothieboard, Cohesion3d, MKS SBase, Azteeg for now, as this performs much faster for laser applications.
• Marlin an Repetier are partly supported and need some specal settings in LW4 because they need laser power commands on separate lines.
• For Marlin >=2.0.6 you should activate the marlin config option #define GCODE_MOTION_MODES and use the gcode generator default insted of marlin.
