Bambu lab p1s

The Bambu Lab P1S is an enclosed CoreXY printer with a four-spool AMS — the mid-range flagship and the most popular choice among serious hobbyists (256×256×256 mm build volume, advertised 500 mm/s, direct drive, bed strain gauge, PLA/PETG/ABS/ASA/PETG-CF support out of the box). This category is for owners choosing between the P1S, P2S and X1C on price-vs-features, printing ABS or ASA in the stock chamber without active heating, debugging AMS swap errors, or chasing hot-end codes and nozzle clogs after carbon-filled composites.

The most common complaints are chamber overheating during long PLA jobs, nozzle clogs after composites, and AMS swap errors. Most of these are solved not by mods but by hygiene: a clean nozzle, up-to-date firmware, and correct spool seating in the AMS. If you just unboxed it, start with first-layer setup and flow calibration. After a year, check AMS feeder rollers and the state of the PTFE tubes. Before printing ASA, verify chamber temperature and door seal.
