Minecraft physics are fun!
A placed igneous extruder can be instantly picked up by dismantling it with a crescent hammer. Its configuration is preserved in the item. It can also be mined using a pickaxe, though this is quite slow.
An igneous extruder can be configured to produce cobblestone, stone or obsidian. When its input tanks are filled with at least 1000 mB of water and lava, the machine will start consuming Redstone Flux to produce the chosen item. Every produced item requires certain amounts of energy, water and lava. When enough energy has been consumed for an item, the required amounts of water and lava are consumed and the output is placed in the output slot.
The amounts of water, lava and energy required depend on the chosen output:
|Cobblestone||0 mB||0 mB||400 RF|
|Stone||1000 mB||0 mB||800 RF|
|Obsidian||1000 mB||1000 mB||1600 RF|
The speed at which an igneous extruder produces items depends on how much energy it can use per tick. This in turn depends on how much power is being supplied, and on the machine’s maximum power usage. A basic extruder has a maximum power usage of 20 RF/t. This can be increased by upgrading the machine to a higher tier, and by installing certain augments.
Fluids and items can enter and exit an igneous extruder through its sides. Every side of an extruder may correspond to its input tanks, its output slot, or both at the same time.
An igneous extruder can automatically transfer items out of any sides that directly correspond to its output slot. This is called auto-output, and occurs whenever the machine finishes processing an item, or every 32 ticks (1.6 seconds) if the machine is inactive.
Which sides correspond to which tanks/slots and whether auto-output is enabled can be configured using the Configuration tab in the machine’s GUI.
An igneous extruder may be configured to respond to redstone signals. It can be in one of three modes:
The current mode can be set using the Redstone Control tab in the machine’s GUI.
When an igneous extruder must stop working due to a redstone signal and is still producing an item, it will finish producing that item before stopping.
An igneous extruder can have a signalum security lock installed to restrict who can access it.
An igneous extruder’s configuration can be saved on a redprint to be copied to other extruders.
When an igneous extruder is active, it emits a light level of 14.
Igneous extruders come in six tiers.
|Tier||Max. power usage||Augment slots||Max. items per auto-output||Note|
|Creative||60 RF/t||4||64||Only obtainable in creative mode.|
An igneous extruder can have augments installed to improve certain properties or to change how it works. Augments can be installed in the Augmentation tab in an extruder’s GUI.
|Auxiliary Reception Coil||Any machine||Increases a machine's maximum power usage (speed) by 1x its base maximum power usage. However, the amount of energy required per operation is also increased. Can be installed multiple times.|
|Pyroclastic Injection||Igneous Extruder||Allows for an igneous extruder to work without water, so only lava is required.|
|Granitic Subduction||Igneous Extruder||Allows for an igneous extruder to produce granite instead of stone.|
|Dioritic Subduction||Igneous Extruder||Allows for an igneous extruder to produce diorite instead of stone.|
|Andesitic Subduction||Igneous Extruder||Allows for an igneous extruder to produce andesite instead of stone.|
