  "community": "r/BambuLab 1lyrd5i asks how to print TPU on an A1 combo with no spool holder, because it will not go through the AMS. The score-55 comment says load TPU and use a generic TPU profile. r/BambuLab 1jrz7xv is about starting TPU. The score-62 comment says dry it, feed it straight into the hotend with as little PTFE as possible, and print from a dry box if you have one. The score-22 comment says hardness runs from about 60A to above 60D. That range is the comment. r/FixMyPrint 14g1pmc is scarring on a TPU print. The score-12 comment says check Z for a bad spot, grease, or dust. No excerpt was supplied for r/BambuLab 1qewlf8 or 1jwyyjg.",
