The original AMS's actual weakness is feeding, not humidity - see ki-bambu-ams1-feed-jams: cardboard and lightweight spools bind or unspool inside it, and filament snapping in the under-unit PTFE tubes needs partial disassembly to clear.

Independent and owner evidence is consistent and unflattering: AppleInsider (September 2025) lists 'multi-color printing leads to a lot of waste, longer printing times' as a con and describes purge being ejected through a hole in the rear of the machine onto the desk or floor. An AD5X owner (r/FlashForge, retrieved 2026-09-06) ran a 125 g print and reports roughly 0.25 g dumped after every single color change on top of the configured flush volume, and that the flush-into-object setting appears not to consume the designated flush.

That is the number to use. The other measured datum is historical and much worse: 3DPrint.com's March 2025 review found the machine purging repeatedly for nearly five minutes per color change and burning more than 1.75 kg of TPU on a 150 g model; no source after March 2025 reproduces it, so it is recorded as an early-firmware defect (ki-flashforge-ad5x-purge-runaway-2025) rather than as the machine's behavior today.

It counts for the Formbot VORON 2.4 kit and it does NOT count for the Formbot Troodons. It counts for the Voron because the Voron 2.4 has no manufacturer: it is a community design published by VORON Design under GPL-3.0, ArmoredTurtle's BoxTurtle is the Voron ecosystem's own AMS answer and says so - 'an AMS for any klipperized printer regardless of form factor but VORON Design printers in particular' - and Formbot, the vendor that sells the Voron 2.4 whole-printer kit, sells this unit from the same store. That is exactly hard filter (c)'s third clause, 'a whole-printer kit whose vendor sells the multi-material unit for it'. It does NOT count for the Troodon 2.0 Pro or the Troodon 2.0 Pro Mini, and the earlier version of this file said it did. Three things sink that: (1) the Troodon is not a whole-printer kit - this file's own record sets is_kit false and quotes Formbot calling it '95% pre-assembled' - so the third clause does not reach it, and the second clause needs 'an official addon from the printer's own manufacturer', which means an addon Formbot offers FOR the Troodon; (2) no source anywhere says this unit fits a Troodon. Formbot's BoxTurtle product page names no printer model at all, and Formbot's own site navigation files BoxTurtle under Voron Series and under Spare Parts > Voron Series - never under Troodon Series (verified on the Troodon 350 page, the Troodon Mini page and the Information page, 2026-09-06); (3) 00_BRIEF's INCLUDE_KITS knob names 'Box Turtle' outright in its list of bolt-on multi-material kits that are NOT a qualifying multi-color path, and the one exception the rules grant is the community-designed machine with no manufacturer. The Troodon has a manufacturer. The two Troodon configurations are therefore restructured as bare printers with no_multimaterial_path true and the BoxTurtle option named in third_party_mm_kit_note, which is the same treatment unranked.json gives a Sovol SV08 with a Co Print kit. By the same test a Box Turtle on a Rat Rig V-Core 4.1 does not qualify either - see cfg-ratrig-vcore41-idex. compatible_printer_ids still lists the Troodons because both are Klipper machines and nothing says it will not physically work; that is an engineering guess, not a sourced fact, and it is flagged in unverified. WHAT IT IS. Four lanes, each with its own extruder motor and a low-drag top-fed electric respooler, merging into a hub with a sensor and a single outlet to the toolhead, buffered by a TurtleNeck. Software is the AFC-Klipper-Add-On, which needs root access on the printer's single-board computer and Klipper or Kalico 0.12.0 or newer. WHAT FORMBOT'S 189.05 USD DOES NOT INCLUDE. Its page says the same thing as its Voron kit page: 'This kit doesn't include any 3d printed parts.' Formbot sells the printed set for US 85.00, which the independent reviewer calls fair given the alternative is three or four rolls of filament including TPU and clear. It also does not include the toolhead-side printed parts for the filament cutter - those the owner prints from the FilamATrix repository to match their own extruder and hotend, which is only possible once the printer works. Formbot does state that the current version includes the FilamATrix hardware. CONTROL BOARD - UNRESOLVED, AND IT MATTERS. ArmoredTurtle explicitly warns buyers to 'ensure they are sourcing a kit that comes with an AFC-Lite controller board' and names a vendor shipping a substandard AFC-X board that died in two days. Formbot's product page does not itemise which board is in the box, and Formbot's BoxTurtle collection sells only three things - this kit, the printed parts and an enclosure kit - with no separate board SKU, which is consistent with the board being included but is not proof. This is the single most consequential unverified fact in this file and should be confirmed with Formbot before purchase. The project itself is healthy: ArmoredTurtle/BoxTurtle is GPL-3.0, 1,175 stars, last pushed 2026-08-05 (GitHub API, 2026-09-06). Formbot's listing shows 440 sold and 5.0 from 7 reviews. AUDIT 2026-09-06: Formbot is not on ArmoredTurtle's vetted vendor list (checked 2026-09-06, see ki-boxturtle-nonvetted-vendor-boards); vetted US vendors sell the same kit for 299.99 USD against Formbot's 189.05 USD, and the price gap is unexplained.

Snapmaker's own wiki shipment-schedule page confirms it: a Top Cover ordered through the official store after 2026-01-13 for the US has an estimated ship window of November 01-15, 2026 and an estimated delivery window of November 15-30, 2026. This is a back-ordered accessory of a product that physically exists and is being delivered to Kickstarter backers in September and October 2026 - it is not vaporware - but a buyer ordering today would wait roughly ten weeks. The store page carries only 4 reviews.\n\nWHAT IT DOES (Snapmaker spec, 2026-09-06): PC housing, magnetic front door, 424 x 510 x 307 mm, 3.6 kg (U1 + cover = 584 x 510 x 753 mm, 21.8 kg). Passive chamber management reaching up to 50 degrees C at 25 degrees C ambient with the bed at 100 degrees C (Snapmaker Lab figure, 30 minutes). Three-stage air filtration: G3 pre-filter, coconut-shell activated carbon, H12 HEPA, supporting VOC and particulate filtration. Filament support with the cover: PLA, PETG, TPU, PVA, PET, ABS, ASA, PA, PC.\n\nIMPORTANT LIMITS, all from Snapmaker's own footnotes: the three-stage filtration works ONLY in internal-circulation mode. External-circulation mode is heat exhaust and does NOT pass air through the filters, so when printing PLA/TPU/PVA the chamber air is vented into the room unless you attach an exhaust hose - Snapmaker provides a printable adapter model rather than a part. High-temperature and heat-sensitive filaments cannot be run in the same print. The filtration system shuts down 10 minutes after a print ends and Snapmaker recommends waiting those 10 minutes before opening the door after ABS/ASA/PC/PA. Replacement filters are 'available soon' and were not purchasable on 2026-09-06, so the consumable cost and replacement interval of the filter are unknown.\n\nVENDOR NOISE CLAIM, NOT A MEASUREMENT: Snapmaker's FAQ says the cover 'helps maintain average operating noise under 50 dB in internal circulation mode'. No independent measurement of this exists; treat it as marketing.", "_file": "snapmaker.json" } ]
