Viki 2.0 Installation

Upgrade your Viki LCD Controller to the newer Viki 2.0 LCD and enjoy tetherless printing without a USB-to-computer connection. The Viki 2.0 LCD provides improved visual indication of print status, including temperature and peripheral activity, and features a new black faceplate and dual-color LED ring around the knob.

You can order a full Viki 2.0 kit, or the LCD panel only. The Viki Holder model is available for download here if you wish to print it yourself.

Note: The kit option is required if upgrading from a Viki 1.0 and includes a 3D printed enclosure, wiring harness and mounting hardware that easily attaches to your Gigabot frame. The Viki 2.0 LCD is only compatible with Gigabots equipped with Azteeg 2.0.

Tools Needed: 

• Philips head screwdriver
• 5.5 mm wrench or pliers
• 2mm Allen key
• 3mm Allen key
• Heliostat

Important Safety Information: Disconnect your Gigabot from power and make sure it is turned off during the installation process!
