What it does#

The Kerf Mill saws wood. A log goes in; planks and Sawdust come out. It gets more planks from a log than the crafting grid does, and the sawdust is a bonus that burns as fuel.

A worked example: one Oak Log becomes six Oak Planks and some sawdust, against four planks from the crafting grid.

Building it#

Kerf MillCrafting Table

Using it#

Put logs in the input slot. Planks collect in the output slot and sawdust in the byproduct slot. The example shows a Kerf Mill with a Manifold fitted, so it saws three stacks at once.

Every log works#

You do not need a recipe for each kind of wood. When the game loads, Enthalpy looks at every item tagged as a log and finds the planks its crafting recipe makes. The mill then saws that log into one and a half times as many planks, plus one sawdust. Modded wood joins in on its own, as long as it has a log-to-planks recipe. Logs, stripped logs and the all-bark wood blocks are all covered. Here is one of them:

The sawdust always drops from a log; you do not need to count on a chance.

Automation#

Out of the box every face takes items and gives items:

Every face Input & Output (takes items and gives items). Auto-input off, Auto-output off.

Feed logs in by hopper or pipe and pull planks and sawdust from any face. Turn on Auto-input or Auto-output to work with neighbouring chests. Side configuration explains faces, modes and redstone control for every machine.

Upgrades#

A tier kit makes the machine faster, enlarges its buffer and opens module slots. Power use below is per lane while it works.

  • Celerity Module · up to 8
  • Economizer Module · up to 8
  • Manifold Module · up to 2

Three modules matter to a processing machine:

  • Celerity speeds the work up by 50% each, but every operation costs 50% more energy.
  • Economizer divides the energy each operation costs and grows the buffer by the same factor, one step per module of 50%. It does not change the speed.
  • Manifold opens two more lanes each, so the machine works on several items at once. Every extra lane draws its own power.

Four Celerity modules give 3× the speed, at 3× the energy per operation, so the machine draws 9× the power while it works. Four Economizers cut each operation to 33% of its energy at the same speed. With the defaults, equal numbers of Celerity and Economizer modules cancel on cost: you get the speed and pay the original energy per operation.

Good to know#

  • Its running sound is a low hum. Turn it off with Sounds on the Configuration tab.
  • A full sawdust slot stops every lane, even though the sawdust is a bonus. Burn it, or pipe it away.
  • The mill works from the crafting recipes at load, so a datapack that changes a log's planks changes what the mill gives.

Authored recipes are datapack files of the enthalpy:kerf_mill type. The log recipes are built when recipes load, from every item in the minecraft:logs tag that has a single-log crafting recipe for planks.
