SpoolFlux vs ReSpool

iOS app for reading and writing NFC tags on 3D printer filament spools. Supports OpenSpool, OpenPrintTag, ACE Pro, and TigerTag. Features: - Multiple NFC formats: read and write OpenSpool (ISO 14443), OpenPrintTag (ISO 15693/SLIX2), ACE Pro, TigerTag, and OpenTag3D - TD1 filament scanner: automatic color detection via USB-MIDI (connect the TD1 device using a Lightning/USB-C adapter) - Extruder temperature range (150–420 °C, 5 °C steps) with Min/Max slider - Heated bed temperature range (0–160 °C, optional) - Temperature presets per material - 24 predefined colors, add your own - Multicolor filaments: create multiple colors per filament (e.g., for multicolor spools) - 42 materials (PLA, PETG, ABS, TPU, PEEK, and more), add your own - 21 material variants (Matte, Silk, Rainbow, Glow, Carbon, and more), add your own - 42 predefined filament brands, add your own brands - Optional filament properties: weight (250 g–10 kg), diameter (1.75 / 2.85 mm), Spoolman-compatible spool ID - Filament library: save, load, search filaments, and export/import as a .sftemplate file - OpenFilament Database (OFDB): import filament data from the community database - JSON preview with syntax highlighting

ReSpool writes the NFC tag that Anycubic ACE 3D printers read to identify filament. Anycubic only sells spools with these tags, so filament from any other brand is invisible to the printer. ReSpool writes a blank NFC sticker with the material, colour and printing temperatures of whatever spool you actually have, and the printer then recognises it like its own. WORKS WITH HOME ASSISTANT Every tag gets a unique spool ID, carried in the SKU. The hass-anycubic_cloud integration reads it from the Anycubic cloud, so Home Assistant can tell two identical reels apart and track how much filament is left on each. Connect the app to Home Assistant and the Library shows what is left on every reel, straight from what the printer has extruded. THE WHOLE ANYCUBIC RANGE A catalogue of more than 600 genuine Anycubic product codes ships with the app and works offline — every colour of every line, with temperatures taken from scans of real spools. Pick a product and write it straight to a tag, or scan a genuine spool to add it for everyone. OPENPRINTTAG TOO Read and write Prusa's open standard, as shipped on every Prusament spool, on ICODE SLIX2 tags. OpenTag3D and OpenSpool are supported as well. HONEST ABOUT WHAT IS LEFT Put a part-used reel on the scales and the app works out the filament left, writes that to the tag, and can update it later on the same tag — same spool ID, same history. Photograph a spool to pick up its colour. TWO TAGS PER REEL The ACE reads one face of the reel. Write a second sticker for the other side carrying the same spool ID, so the reel is recognised either way up and Home Assistant still sees one spool. SAFE BY DESIGN - Only the data pages are ever written; the UID, lock bits and configuration pages are unreachable - A full backup is taken before a single byte is written, and can be restored - Every page is read back and compared byte for byte - A tag already holding spool data stops and asks first - Pages that already hold the right bytes are skipped Needs blank NTAG213 stickers (or larger); Anycubic's own tags are password-locked and cannot be reused. OpenPrintTag needs an ICODE SLIX2. Requires an iPhone 7 or later.
