GLCD panel Build

The panel and its shield is pretty straight forward to build and install.
  • Shield build
    • Install the missing pins 
    • Install the 5VDC regulator 
  • Plug the shield onto the smoothie
  • Install the 2 shield-to-panel cables making sure they are correctly connected
  • Check the configuration file to assure the panel is enabled and configured correctly
Make sure that you don't make these mistakes:

Configuration

At the time of this post I was running "firmware-cnc"
Enable the panel module and un-comment what is needed for this display.
Link is here: http://smoothieware.org/rrdglcdadapter look for the configuration setting for the GLCD. 

Ready to run, looks like this

Smoothieboard GLCD Shield

The display is connected to the Smoothieboard via this shield which plugs on top of Smoothie :

Note: Additional pins must be added to the Smoothie to accommodate the shield. Install pins in the RED circles.

Cable orientation. I labeled my shield and the cables so that they don't get reversed.
