Quantum Digital Miner

Type	Machine
Stack size	1 (on 1.21.1 since 1.2.1, as on 1.20.1; stacks already in a world keep their count)
Size	3 × 3 footprint, 2 blocks tall (main block + 17 bounding blocks, same footprint as Mekanism’s Digital Miner)
Energy	Follows Mekanism’s Digital Miner formula (usage.digitalMiner, storage.digitalMiner) × quantum_miner.energyMultiplier (4.0 by default): 4,000 J/t and 200,000 J of storage with no upgrades, more with Speed and Energy Upgrades, radius and height range
Upgrades	Speed, Energy, Anchor, Stone Generator (Mekanism’s own Digital Miner upgrades)
Side configuration	No, one of only three machines in the mod without Mekanism’s side configuration screen (the others are the Petrogenic Synthesis Plant and the Quantum Network Controller); item flow follows the fixed port layout below, switched between Local, Quantum and QIO from the Quantum link column

What it does

The Quantum Digital Miner mines blocks in a cube around itself exactly like Mekanism’s Digital Miner: same filters (item, block tag or mod id, with an inverse mode and a required replacement target), the same search and mining rules, and the same Speed, Energy, Anchor and Stone Generator Upgrades. What changes:

• Radius: up to 128 blocks (server limit quantum_miner.maxRadius), against the Digital Miner’s own limit of 32.
• Speed: mines eight times faster than a Digital Miner with the same Speed Upgrades (quantum_miner.speedMultiplier; four times before 1.3, and a server config still at the old 4.0 is moved to 8.0 once when 1.3 first loads it).
• A limit per game tick: whatever the speed and however many Speed Upgrades or Time Overclockers it has, one Quantum Digital Miner mines at most 32 blocks in a game tick (quantum_miner.maxBlocksPerGameTick; maxBlocksPerTick, 8, still limits each single run of its work).
• Energy and items through quantum frequencies: besides its own ports and battery (like the Digital Miner), it can draw energy from, and send mined items to or pull replacement blocks from, a quantum frequency shared with other machines (Mekanism’s Entangloporter-style buffer: one item type, one energy pool) or the QIO network. Choose the source for Energy, Import and Export independently from the Quantum link column.
• Relocation: once its current zone is fully mined, it can be moved to a neighbouring zone it has never mined, using a Digital Miner Companion: see Digital Miner Companion for how. The Digital Miner Companion can also link to, read and remote-control a plain Digital Miner, but only a Quantum Digital Miner relocates.
• Chunk loading: it never loads chunks on its own. With an Anchor Upgrade it behaves like the Digital Miner, its own chunk and the chunk currently being mined stay loaded, and the search may briefly load nearby chunks. Without one, an unloaded chunk in range is treated as empty.

Its front face carries a live screen: a state (SEARCHING, MINING, an amber WARNING once mining has been held up for three refreshes in a row: a single stalled tick is not a fault, since a machine at full speed empties its energy buffer every tick), the percentage of the zone already mined, the blocks left, and a bar of filled and empty cells. The screen goes dark when the machine is off and keeps its last picture once the zone is finished.

Since 1.2.0 it also tells you when it finishes, is held up or has moved (see Notifications), and its New filter window has quick filters and saved filter lists.

Mekanism’s own Visuals tab draws the mining zone in the world as one translucent box, at any configured radius up to 128: Mekanism’s own Digital Miner stops showing it past radius 64.

This is not an ordinary shaped recipe: crafting it carries the Digital Miner’s upgrades, stored items, overflow storage, energy (as much as the new machine holds) and owner into the new Quantum Digital Miner, the same way Mekanism’s own recipes carry a machine’s contents to its next tier. The Digital Miner’s filters and mining settings are not copied: set them again on the new machine (the Digital Miner Companion can Pull them from the old machine before you craft and Push them to the new one).

Ingredients that are already configured never block the craft, in a crafting table or in the Crafting Terminal of Applied Energistics 2. The upgrades of the Digital Miner go into the new machine; the upgrades of the other ingredients (a QIO Importer with Speed Upgrades, an Entangloporter with an Anchor Upgrade) join them when they fit within the maximum, and otherwise come back as upgrade items in the crafting result, together with any item the new machine has no room for. Nothing is lost or duplicated.

Getting started

1. Gather the ingredients above; the Digital Miner’s upgrades and stored items travel into the new machine, its filters and settings do not.
2. Craft the Quantum Digital Miner.
3. Place it and give it power (its own ports, or a Quantum/QIO energy source set up later).
4. Right-click it to open its screen, then click Config (or shift + right-click the machine) to open the Configuration screen: set the radius (up to 128 by default), the Y range, filters, Silk touch, Auto-eject and Auto-pull, and inverse mode: the same screen and rules as the Digital Miner.
5. Optionally, pick a Quantum or QIO source for Energy, Import or Export from the Quantum link column.
6. Click Start.

The interface

• Status screen (top left): the machine’s state (Running, Low Power or Not ready, or a warning such as full output or missing redstone), the search state, and To mine: n.
• Export / Import / Silk rows: horizontal OFF | ON switches for auto-eject, auto-pull and Silk touch.
• Energy bar: a vertical power bar that warns when the buffer cannot cover the next tick’s cost.
• Missing block slot: shows the replacement block the machine is waiting for, if any.
• Visuals and Energy tabs: Mekanism’s own tabs, for the zone outline in the world and the energy summary.
• Start / Stop / Config / Reset buttons, enabled or disabled exactly as on the Digital Miner’s own screen.
• Quantum link column: one card per source (Energy, Import, Export) showing its state (connected, empty, no frequency, or “like the Digital Miner”), each with a Configure button that opens Mekanism’s own frequency selector to choose Local, a named Quantum frequency, or QIO. The column also shows the current zone number and radius.
• Opening Config shows the Digital Miner’s own configuration screen. It is tall: if it does not fit your window (for example at GUI scale 3 in a 1280×720 window), lower the GUI scale. Its left panel has, top to bottom: “Filters: N”; “Block radius: N” with a field and a check button to set it, and its limits beside it (“Min 0” over “Max 128” with the default server setting); “Min Y level: N” and “Max Y level: N”, each with a field, a check button and its own “Min” and “Max” (the world’s lowest block up to the zone’s top for the minimum, the zone’s bottom up to the world’s last block for the maximum; the server clamps what you type to those same limits); the inverse mode switch; the replacement block slot (drag a block onto it, Shift-click to clear) and the button that requires it. To the right, the filter list with its scroll bar and the New filter button; a back arrow at the top left returns to the main screen.

Notifications

Your Quantum Digital Miner tells you, with a notification and Minecraft’s notification sound, when:

• mining is complete (“Mining finished”, or “Done in the loaded chunks only” when part of the zone was not loaded);
• mining is paused, with the reason: not enough energy, storage full, overflow items to clear, replacement block missing, placement refused, or area not loaded;
• a relocation is complete.

Each notification gives the dimension and the machine’s X, Y and Z. Only the owner receives them, and only while connected. Beyond eight at once, the rest are counted in a single “+N more” notification. Turn them off with the client setting notifications (see Configuration); that turns off the notification and its sound for the whole mod.

New in 1.2

Quick filters and saved filter lists

The New filter window starts with two shortcuts, and only the filter list changes: radius, height, Silk Touch and every other setting stay as they are.

1Quick filters

Ready-made ore tag filters: iron, gold, coal and redstone, plus copper, lapis, diamond, emerald, tin, lead, osmium and uranium when their tag exists. Replace the list with one, or Add it at the end; ores from other mods are included.

2Configurations

Save current filters under a name, then load the list on any miner with Replace or Add. Your own library, in the world or on the server: up to 32 lists of 128 filters.

1The New filter window starts with Quick filters and Configurations

2Quick filters: Coal chosen, its tag c:ores/coal, Replace or Add

3Add: “Coal added (1 filter)”, the filter is in the list

4Configurations: the list saved as “Charbon”, ready to load on any miner

• Quick filters: a short catalogue of ore tags. Iron, gold, coal and redstone are always listed; copper, lapis, diamond, emerald, tin, lead, osmium and uranium are listed when their common ore tag exists in the instance. Each makes an ordinary Mekanism tag filter on the common tag (for example c:ores/iron), so ores added by other mods are included. Replace makes the list that one filter (a confirmation asks first when the list is not empty); Add puts it at the end of the list unless a filter of that tag is already there. A tag that Mekanism’s miner blacklist excludes is shown as “Tag excluded from mining” and cannot be used; a tag missing from the instance says “Tag missing”; one already in the list says “In the list”. The world is never scanned and no chunk is loaded to do this. The filter list stops at 128 filters.
• Configurations: Save current filters stores the miner’s filter list under a name, and you can load it on any miner with Replace or Add, overwrite it or delete it. Each player has their own library, in the world or on the server (the window says “Personal · this world” or “Personal · this server”): up to 32 lists of 128 filters, names up to 24 characters. A list that cannot be read is kept and not applied (“Unreadable”); one that needs a tag or mod that is missing says “Tag or mod missing”.

Automation

• Ports, same layout as the Digital Miner: items in on top, items out through the centre of the upper rear face, energy on the bottom (also usable on the left and right), reachable at the centre of each face. Put a chest directly against the outside of that rear port and set Export to Local and Auto-eject to ON. With no Mekanism side configuration on this machine, this layout is fixed: switch a face’s role between Local, Quantum and QIO from the Quantum link column instead of Mekanism’s face editor.
• Keeps on break and re-place: filters, settings, upgrades, energy, inventory, security, redstone control and the history of finished zones all travel with the machine. Its current search does not: like the Digital Miner, it searches again after being reloaded. Its energy, QIO, import and export frequency links travel in the item only when it was the owner who broke it; broken by anyone else, or an old or forged item, the miner is placed unlinked (the source mode you chose stays), so nobody can draw on the owner’s private network.
• Chunk loading: only with an Anchor Upgrade installed, and only its own chunk and the one it is mining: see What it does above.

Configuration

Server config, section quantum_miner:

Key	Default	Range	Meaning
enabled	true	–	Turns searching and mining off entirely
maxRadius	128	1–128	Largest mining radius players may set
speedMultiplier	8.0 (4.0 before 1.3)	1.0–16.0	Mining speed compared to a Digital Miner with the same Speed Upgrades
energyMultiplier	4.0	0.0–64.0	Energy use and base storage compared to Mekanism’s Digital Miner config
maxBlocksPerTick	8	1–64	Hard cap on blocks mined by one machine in a single tick
maxBlocksPerGameTick	32	1–1024	Hard cap on blocks one machine mines in a whole game tick, however many times its work is run in it (a Time Overclocker runs it again and again)
maxChecksPerTick	512	16–65,536	Hard cap on positions examined in a single tick
searchBudgetMicros	2,000	100–50,000	Server-thread time per tick shared by every running search
searchThreads	1	1–4	Background threads analysing chunks, shared by every Quantum Digital Miner
searchMaxPendingChunks	8	1–64	With an Anchor Upgrade, chunks a search may load at once (short-lived, never blocking)
verboseLogs	false	–	Extra logging for debugging

Relocation itself (triggered from the Digital Miner Companion) has its own relocation section: see Digital Miner Companion.

Client config (mekanismengineering-client.toml): notifications (default on) turns the miner’s notifications and their sound off for the whole mod. The server still sends them.

Relocation safety

A relocation either completes or is undone, leaving the world as it was. If an undo itself cannot put a block back, the server stops for safety and replays its journal at the next restart, instead of silently losing the record of what was moved. This is deliberate; it has been the behaviour since 1.1.1.

Tips and troubleshooting

• Screen stuck on a warning: it only turns amber after three refreshes with nothing mined in a row: check the reason shown on the status screen (energy, full output, redstone, missing replacement block).
• Low Power: Speed Upgrades outrunning Energy Upgrades, exactly as on a Digital Miner: add Energy Upgrades, or switch its energy source to a Quantum frequency or QIO from the Quantum link column.
• Only this machine relocates: a plain Digital Miner linked to a Digital Miner Companion can be read and remote-controlled, never moved.
