Installed an upgrade on the new printer. The Panda Touch is a touchscreen upgrade that provides extra functionality. The Panra Touch allows you to change filament and make other changes to the configuration of the printer without having to use the app on your phone or tablet. It allows you to control multiple printers from the one screen. It also allows direct printing from USB thumb drive. All in all it doesn't provide a lot of extra functionality, but it does look cool. I printed a bracket that mounts it next to the factory screen.
