I will try to outline the differences in the future.

would be nice to get a encrypted gcode option for firmware so authors can get paid for their 3d prints easier.

Great Peice of hardware, can be purchased on ebay for under 60 dollars

  • ramps 10 dollars
  • arduino mega
  • 5 axis support


  • Ramps-FD   Geetech    $39
  • arduino uno – $10
  • 5 stepstick drivers $10
  • 6 axis support

I was able to get mine going with marlin4due without too much hastle, the ribbon connectors were upside down for the LCD so cut off the nobs and rotate them till you get backlight when arduino is powered on.
