Kiln 1.2.0

Kiln 1.2.0: every file Kiln makes now carries free proof — verify any STL or 3MF at kiln3d.com/verify. The web app finishes what you make (textures, photos, logos, restyles) and can now sculpt free-form organic shapes alongside precise parts, both free. Recovery gets smarter — skip a failed part mid-print, resume a Klipper print after a power loss, triage a whole fleet after an outage — and Kiln gives straight, honest answers on skin-contact safety and the magnets in your design.

Kiln 1.1.9

Kiln 1.1.9: it updates itself with your go-ahead, designs objects without an API key, and shows a preview every single time it makes something. Free accounts sign in to the web app, accepting the Terms is a one-time tap, and saved decorations follow you across devices. Business and Enterprise add dimensioned production drawings and broader chemical-resistance coverage.

v1.1.8

Kiln 1.1.8 stops prints that physically can't succeed before they waste filament, adds a Supported Printers page (kiln3d.com/printers) so you can check your machine in seconds, and answers whether a printed part will survive gasoline, bleach, or a summer in the sun, honestly, with the safety warnings free. Paid tiers add cited glue recommendations for joining printed parts, materials imported straight from a manufacturer datasheet, and factory-grade work instructions in seven languages.

v1.1.7.1

Local tool calls now count on your /stats. When you're signed in, the CLI and agent work Kiln does on your own machine shows up on your /stats dashboard, not just activity from the web app.

Kiln 1.1.7 — four more Bambu printers, and AMS drying built in

Four new Bambu Lab printers, dry your filament right from Kiln, and clear a backed-up queue in one step — all free.

New

• Four more Bambu Lab printers — the X1E, P2S, A2L, and the enclosed H2S. Recognized on connect: temperature limits, build volume, per-material settings, and a tuned slicer profile, no manual setup.
• AMS drying, free for everyone — on Bambu printers with an AMS 2 Pro or AMS HT, start/stop a drying cycle and see how damp the filament is, time remaining, and the dryer's settings.
• Clear your whole print queue in one step, free — empty a backed-up queue (or one printer's jobs) with a preview of exactly what'll be cancelled. Never touches a print that's already running.
• Designs tailored to your printer — factors in your machine's real build size, materials, and temperature limits, for every printer Kiln supports.
• Wet-filament awareness — names moisture as a likely cause after a failed print, plus a heads-up before you print thirsty materials. Any printer, any material; never blocks the print.

Changed

• Emergency stop now also halts the AMS dryer on Bambu (AMS 2 Pro / HT) — one printer or the whole fleet, matching whatever you stopped.

Fixed

• A Bambu P1P could be misidentified as an X1C — corrected the serial-prefix map.
• Clearer guidance when an A1 nozzle-blob check pauses a print.
• A jammed/overloaded extruder now records as a mechanical failure in history, not an unlabeled error.

v1.1.6 — printers that show up on their own

Highlights

• Printers show up on their own — Bambu Lab printers now appear in network discovery; no more adding each one by hand.
• Prints route to the right AMS spool — Kiln loads the correct tray (matching your material when you name one) and reports which tray it used.
• Community learning is reliable end to end — every print you monitor contributes its anonymous outcome automatically, and being offline when a print finishes no longer drops the result.

Fixed

• Kiln-generated models slice reliably every time.
• No more lost results when several Kiln sessions share one machine.

v1.1.5.2 — update notifications

Kiln tells you when there's a new version — whether you're working through an AI assistant or on the command line — and kiln self-update does the upgrade for you.

Full release notes: https://github.com/codeofaxel/Kiln/blob/main/CHANGELOG.md

v1.1.5.1 — Prusa config compatibility

[1.1.5.1] - 2026-05-28

Fixed

• Saved prusaconnect printer configs keep working. The Prusa
  adapter was renamed to prusalink in 1.1.5 with no alias, so existing
  configs pinning type: prusaconnect failed with "unsupported printer
  type." Kiln now auto-detects the old name and uses prusalink,
  logging a one-time notice to update your config — no manual edit
  required.

v1.1.5

[1.1.5] - 2026-05-27

Engravings get smarter — depth that matches your nozzle, the right
flip-axis picked for you, a sanity check that catches text which would
print backwards, and an auto preview of the finished face. Plus:
nozzle wear becomes something Kiln watches across every print, every
printer, every recommendation — heads-up before you print on a worn
nozzle, failure analysis and recovery plans that consider wear, and
material recommendations that flag bad nozzle/filament combos up
front.

Added

• Engraving depth matches your nozzle. Smaller nozzles get
  shallower carves, larger nozzles deeper ones, so the engraving
  always survives the first layer instead of vanishing into the
  squish. Asking for depth below the floor for your nozzle now
  fails loudly with a clear error.
• Bottom-face flip picked automatically based on the face
  shape — so the engraving reads correctly when you flip the
  printed part over.
• Catches mirror-reversed text before you slice. A pure-math
  sanity check on every bottom-face engraving — if any transform
  in the pipeline would print the text backwards, the call fails
  with a fixable error instead of silently engraving backwards.
• Auto preview of the finished engraving. Render shows what
  the underside will look like after the part comes off the bed.
• Engraved text doesn't kiss the edges anymore. Default width
  tightened and a margin clamp added so "KILN" on a coaster sits
  comfortably inside the rim instead of hitting it.
• Heads-up if a print would wear your nozzle out (Kiln Pro).
  Before a print starts, Kiln checks whether finishing this job
  would push the nozzle past its wear limit, and warns if so.
  Warns, doesn't block — your call.
• Every supported printer feeds the wear model on every print
  (Kiln Pro). Bambu, Moonraker, OctoPrint, Elegoo, and
  PrusaLink all report extrusion anomalies to the wear model.
• Failure analysis considers nozzle wear (Kiln Pro). When
  the failure symptoms line up with what a worn nozzle would
  cause, wear surfaces as a candidate instead of always pinning
  on bed adhesion or temperature.
• Material recommendations factor your nozzle (Kiln Pro).
  Asking for an abrasive filament (carbon-fiber, glass-fiber,
  wood-fill, or metal-fill) on a brass nozzle now warns up
  front — brass wears out fast on abrasives. Stainless gets a
  milder caution; hardened steel is the right pairing and stays
  quiet.
• Recovery plans suggest "replace the nozzle" when that's the
  real fix (Kiln Pro) — instead of defaulting to "same
  nozzle, lower temp, try again" when the part actually needs a
  fresh tip.

Changed

• Renamed the Prusa adapter to prusalink. Update saved
  configs that pin type: prusaconnect. No back-compat alias.

Compatibility

• Pair with kiln-pro >= 1.1.5 — product cards inherit the new
  engraving engine, nozzle-aware verdicts, and federation opt-in.

v1.1.4

Native Windows support — install Kiln, connect your AI agent, and
generate designs on a stock Windows machine, with setup made easy.
The release also sharpens overhang detection for cantilevers and
islands, makes AMS Lite filament readings accurate, and puts safety
messages in plain language.

Added

• Native Windows support. The CLI, kiln install-mcp, and design
  generation run on a stock Windows install. The install page
  (kiln3d.com/install) has a Windows walkthrough — Python setup through
  agent connection — with a copy-paste prompt that hands the whole
  setup to an AI agent.

Changed

• Plain-language safety and connection messages. Warnings describe
  what they mean for your print instead of leaning on internal terms.
• Accurate AMS Lite filament readings. The Bambu A1 and A1 mini's
  AMS Lite can't measure remaining filament, so Kiln reports the level
  as unknown instead of a placeholder number.

Fixed

• Overhang detection holds for cantilevers and islands. Kiln
  clears supports only when an overhang is genuinely bridgeable; a
  one-sided cantilever or a floating island keeps "needs supports."
• Clearer diagnostics. kiln doctor warnings name their check,
  and pointing Kiln at a missing model file reports "Mesh file not
  found" up front.
