I am running a Ramps 1.4 with an updated alter of Laser Marlin. I will need a G-Code Streaming program for the full gray scale images. All of the streamers are made for GRBL. Are there any of the streamers that will work with Marlins? Why is everything made for GRBL when GRBL is soooo limited? I am trying to avoid having to use GRBL on my Ramps board if at all possible.
