LUCCA A53 Mini / DP / Vivaldi: Accessing the Main Computer (CPU)

Instructions for how to access, remove, and open the main CPU on any La Spaziale S1 machine. This includes the Lucca A53 and Vivaldi II models.

You'll need:

- Phillips Screw driver

Keep scrolling to the end of the article for updates to post-2021 S1 machines.

First, you'll need to remove the panels from your machine.

Locate the CPU attached to the right side of the machine.

Remove the three screws fastening the CPU onto the frame of the machine. 

Remove the heating triac from the top of the CPU, pushing it off to the side. 

Pull the CPU box out through the back of the machine, careful to put all pressure on the casing of the box. It will require some wiggling and pulling wires aside, but it will pull out! 

Once out, you can remove the three screws holding the outer box casing together. 

Open up the CPU like so, and inspect your wiring, removing it if need be. 

UPDATE: Post-2022 Lucca A53 and Vivaldi II machines now feature an updated Universal S1 Main Computer equipped with Bluetooth functionality. Below you'll find photos showing what that board looks like and how to set it up.
