Deprecated Values¶

Klipper occasionally deprecates specific configuration values as the firmware evolves. When this happens, Klipper will display a warning message during startup, indicating that your printer.cfg contains outdated values that need to be updated.

Below you can find a list of commonly encountered deprecated values along with instructions on how to fix them. For a complete list of all configuration changes, refer to the official Klipper Configuration Changes documentation.

Removal of NTC 100K beta 3950 sensor type.¶

The NTC 100K beta 3950 temperature sensor is deprecated and will be removed in the near future.

In order to solve the problem, search in your config for sensor_type: NTC 100K beta 3950 and replace it with sensor_type: Generic 3950.

Most users will find the Generic 3950 temperature sensor more accurate. Anyway you can continue to use the older (typically less accurate) definition. To do so, define a custom thermistor with temperature1: 25, resistance1: 100000, and beta: 3950.

Removal of rpi_temperature sensor alias.¶

Replace sensor_type: rpi_temperature by sensor_type: temperature_host everywhere in your config.
