Pronterface window question I switched to a Raspberry Pi 3 to use with (Linux) Pronterface for my 3D printer. 

This Pi 3 has a 3.5" 320x480 LCD display. When Pronterface is loaded, only part of its window can be seen and some of the UI elements are unreachable. I have the Pronterface source code from GitHub. 

Where do I start to shrink the app window?
You can change your Pi's resolution using raspi-config or the Raspberry Pi Configuration app. 

To use raspi-config, access Terminal and run raspi-config. Then navigate to Advanced Options &gt; Resolution. 

If you'd rather use the GUI, open the Raspberry Pi Configuration app and select Resolution from the resultant dialog. This may help with the rendering issues.
