5 Layers of the 1 Overhead Lossless Bedrock Breaker with Integrated Piston Placers and Conveyors

Features:

• Only 1 hopper line
• Only 2 preplaced rows of pistons per breaker
• No downtime caused by breakers waiting on the piston line to be placed
• Very cheap piston conveyors

To spawn the bots run:

/player _b-1 spawn at (1 block above minecart) facing 45.0 -44.0
/player _b-1 mount
/player _b-1 use interval 1

It is recommended that you give each bot a stack of pistons beforehand. This provides a buffer against junk items which are collected by the hopper minecarts and could end up in the bot's hand. This is most common on the first layer where there are blocks in between the bedrock.

The breakers are not weather proof and not liquid proof to liquids on the edges. You will have to remove these before the breakers reach them.
