Athena II – 16K 8-Bit FPGA Board Installation

This guide walks you through the process of replacing the existing 3-bit FPGA board in your Athena II printer with the 16K 8-bit FPGA board.

The procedure involves removing the bottom cover of the printer to access the electronics compartment and carefully disconnecting and reconnecting several internal cables. No special tools are required beyond standard hex keys, and the upgrade can typically be completed in a short amount of time.

Before starting, make sure the printer is fully powered off and unplugged, and remove the resin vat and build plate from the print chamber to prevent spills or damage when the printer is placed on its side.
