DesktopFolder | Fast Bedrock Breaker - Proof of Concept (Minecraft 1.15.2) @DesktopFolder | Uploaded 4 years ago | Updated 2 hours ago
A flying machine that breaks a one-wide line of bedrock, with one bedrock being broken per 35 game ticks (or 1.75 seconds, at 20 tps).

Thanks to Totorewa and BattleFishMan for help with design.

Notes:

Although I'm pretty sure it's possible to move this machine back & over, I'm not sure how easy that would be or if it would be worth it to do so for this design versus a different one. Although Mojang has removed a lot of bedrock breaking technology, it seems like there are still a lot of approaches for doing so, and it stands to reason there's probably something better than this for making a 3-way breaker. At least this one is fast.

This setup is tested on Minecraft 1.15.2. It should work on any versions with honey blocks. I've also done minor testing rotating it around, which worked.
