A fast 3-way (or, if you prefer, N-wide 1-way) bedrock breaker for Minecraft versions 1.15.2 and 1.16.1. (To start this machine, refer to this video: youtube.com/watch?v=kgPYbadSzMw which also covers player loading.)

The 3-way TNT duper used in this machine was found to be inconsistent in some situations. An updated version with a TNT layout by Sarah has been created and appears to fix this bug while still being nondirectional. If you encounter any problems, please let me know.


1.13+ (honeyless) version: bilibili.com/video/BV1gK411N7nn

Update (August 2) Even 11.19 seems to have extremely rare issues with the TNT duper. Will investigate again in the future.

Updated litematics & world download zips (Version 11.19 - Uses Sarah's duper):

I've gone ahead and removed the links to the previous world download and litematics; if you for whatever reason need them, send me a message on discord.

This is a prototype of sorts, and while it is perfectly servicible for first-layer bedrock breaking, moving it down will require either breaking a larger area with the previous runs of the breaker, or using a more compact breaker for the bedrock that this machine can't break. As breaking bedrock is fairly expensive post-1.12, it's recommended to do the latter. (Alternatively, a stripped-down version of this machine could be used, and the pistons/slabs manually placed and moved)

I will make a more detailed explanation video for this machine in the future. However, this is essentially just a lot of slimeblocks, pistons, observers, and miscellaneous other blocks, arranged in a somewhat disturbing and appallingly inefficient pattern.

Regarding the necessity of using pistons as 'fuel' to break bedrock, although this is a somewhat frustrating change since 1.12, I don't think this should be a major concern for the kind of server that would be using a machine like this. If you're considering building this in singleplayer, however, or on a smaller server (or, really, any server without a couple witch farms) I would strongly recommend doing the math first. (To create a 300x300 perimeter, WITHOUT taking overhead into account, would require (300*300*5/(64*9)) = 781.25 stacks of redstone blocks (28.9 chests full!)

Common Questions (for video avoiders):
- Works for any bedrock layer.
- Requires (1) downwards facing piston and (1) stone slab (or equivalent) as input per bedrock broken, as is the norm in post-1.12 bedrock breaking. Pistons can be retrieved by player; I do not recommend attempting to retrieve the slabs.
- Is not directional (although I only tested in litematic direction & 90 degree rotation... works on my machine!)
- 36 game ticks per bedrock asymptotic (the rate improves the longer the machine is, with 36gt being the limit; however, this is already much faster than past 1.12 designs with just 20 blocks of length). (26gt while breaking bedrock, 10gt while returning)
- Yes, it is large, and has overhead each time it is moved down (but running this at y5 does not require bedrock to be broken, unlike my previously released 1-way design)
- Does not require blocks underneath the bedrock breaker. Does require slabs regardless of whether or not bedrock is underneath. Has sticky blocks at lowest level, so bedrock layer should be cleared of movable blocks.
- There should already exist suitable floor placer designs which could be used to place the pistons and slabs. If not, it should be possible to create a 2-high piston/slab floorplacer to create the 'carpet' required for this machine.

Uses the G4mespeed mod by G4me4u for smooth piston animations & slower camera movement in spectator mode. This only worked for 1 cut in the entire intro, unfortunately.
