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. 

Change the Rotary Dials Rotation Direction

+Ray Kholodovsky (Cohesion3D) In the config file under panel swap the encoder A and B pin #’s with each other.

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.
