This is the brains of the controller, this plugs into board that nornally takes an 8 bit nano.  For the full controller you need Black-N-Blue 2.

32 bit Nano Black-N-Blue GRBL

SKU: 0001
  • This is the Worlds first and only Plug and Play 32 bit Grbl Nano. You replace your 8 bit nano on your Eleksmaker laser engraver for example.

    I designed this because I wanted to be able to do true greyscale and 8 bit processor cannot handle it. Also, I wanted to do faster, higher accuracy engravings.

    Copy your 8 bit Nano settings (steps/mm, accel, velocity, machine travel, directions, etc) to a text document.

    Just plug this in with the same orientation as your 8 bit Nano and paste those settings listed above into the 32 bit Nano and you can use your favorite software and gCode sending applications as before.

    Example engravings which are the laser burning the substrate which in this case is MDF, as the laser scans the image on the MDF, the controller is adjusting the laser power and creating a true greyscale image. You can engrave on MDF, wood, tiles, slate and many other substrates.  Also shown is a $1 mirror from the Dollar Tree.  The faint horizontal, wavy lines on the mirror are due to mirror coating (not the engraving).
