    • The thermistor, which is part of the same module, provides highly accurate temperature measurement.
    • Its reliable structural design ensures consistent performance even under extreme conditions.
    • Unlike some other components, thermistors do not have a specific orientation or polarity. As long as the connector is fully seated, it doesn’t matter which way it’s facing.

However, it seems that some users have encountered issues related to the nozzle temperature and thermistor. Here are some experiences shared by fellow Bambu Lab users:

  • Nozzle Temperature Malfunction:

    • Some users faced nozzle temperature malfunctions after disassembling and reassembling their toolheads.
    • In some cases, the thermistor wire was suspected to be damaged, leading to the issue.
    • Replacement parts (including full assemblies) didn’t always resolve the problem immediately.
  • False Plugins and Connector Challenges:

    • The connectors on the P1P toolhead can sometimes lead to false connections.
    • Ensuring proper seating of cables and connectors is crucial.
    • Users have reported frustration with the delicate cables and connectors during replacement or troubleshooting.
  • Design Flaws and Support Delays:

    • There have been concerns about design flaws, especially when a shorted thermistor can impact the toolhead board.
    • Waiting for replacement parts, shipping delays, and downtime have been common frustrations for users.

If you’re experiencing nozzle temperature issues, I recommend reaching out to Bambu Lab support for assistance. They might provide specific troubleshooting steps or guide you through the process of resolving the problem.
