MC3DPrint

A rebalancing pass over what things cost, plus an Applied Energistics front end for the printers. Crops, doors and beds were all priced wrong, three duplication holes are closed, and the MC3DPrint Terminal lets an ME network order prints paid in Filament Units.

New

• MC3DPrint Terminal. An AE2 cable part that lists everything your networked printers and formed Fabricators can make, and orders it paid in Filament Units instead of ingredients. It dispatches rather than crafts: an order queues a job on a real machine, which does the work at its normal speed, RF draw and filament cost, so an order costs exactly what printing the same item by hand costs. Interruptions hold rather than fail, and filament is spent if and only if an item is delivered. It uses a channel, like AE2's own terminals. Needs AE2 installed; without it the terminal does not exist and nothing else in the mod changes.
• Redstone Module. A fifth printer upgrade, one per machine. The machine emits a full-strength signal from all six faces while actively printing or deconstructing and nothing when idle or stalled, so an inverted signal makes a stall alarm. On a fabricator, only the controller emits.
• Comparator output on every machine. Put a comparator against a printer or fabricator and it reads job progress: 0 for nothing loaded, 1-15 climbing to 15 on the final block. No upgrade needed. On a fabricator, read the controller.
• Un-print the last build. Flip a machine that has just printed into Decon with no region of its own and Start takes that build back as filament. It is masked to the print itself, so the terrain underneath, a chest you put inside it, or a wall you extended are all left alone.
• Get your handbook back. /mc3dprint guide hands one out, and there is now a crafting recipe (Extrudium Crystal plus a Book). The old auto-give was one-shot per player, which left anyone who lost theirs stuck.
• Rename and remove player scans from the Blueprint Repository, so a library holding two scans can tell them apart. Whoever deposited a scan can manage it, operators can manage anything, official builds neither.
• Filament Item Sorter pushes un-windable items to an adjacent inventory instead of jamming.
• More Filament Unit values: Mystical Agriculture and Agradditions, Tinkers' necrotic bone, gunpowder, and phantom membrane.

Fixed

• Doors, beds and double plants were charged twice. Both halves of a two-block piece resolve to the same item, so every door and bed in a build has always cost double, putting the Efficiency break-even out of reach for them no matter how many modules you installed.
• Crops and seeds printed for free. The free-print rule keyed on a block type every crop in the game descends from, so scanning a field of a mod's valuable crops and printing it handed them over for nothing. Planted growth now costs its seed, and a farm can no longer launder itself into filament.
• Three duplication holes closed: an item placed on a wall surviving the block-entity clear, itemless blocks with block entities bypassing strict mode, and modded seeds being windable because the blacklist was a name list rather than a rule.
• A finishing machine stranded its neighbour's job. Two machines whose job areas shared a chunk fought over it, and the first to finish unforced the chunk out from under the one still working, which then hung with no error and no way to recover. Any print farm could hit it. (1.20.1 was never affected.)
• Stairs, fences and walls read as wrong. Parts of a placed state belong to the game, not the blueprint, so on any build with stairs the ghost preview lit corners red and a re-print refused to start as Obstructed, over blocks that were already correct.
• Docking a filament spool crashed the client on 1.21.11 and 26.1. Minecraft moved line width into the vertex in 1.21.11 and the overlay wireframes still wrote the older, shorter one. Earlier versions were never affected.
• The 26.1 jar could be loaded by a NeoForge too old to run it, which surfaced as a crash on startup rather than a version message. See Compatibility below.

Removed

• The Filament Converter. It did what the Filament Winder already does, so it never earned a slot in the progression. A converter already placed in a world will not survive that world's next load, and anything left inside it goes with it, so empty them before you update.

Compatibility

Every version below ships to both CurseForge and this release. The 26.x minimums are exact, because NeoForge still renames API within those lines: an older 26.1 is missing classes the jar links against.

NeoForge 26.1.2.x is published against Minecraft 26.1.2, so a 26.1 instance has to be on that patch to install a loader these jars accept. The mod itself accepts any 26.1.x.

Drop the jar for your version into mods/, replacing any older copy. Optional: Patchouli for the in-game guide, JEI for recipe and FU lookup.
