      When calibrating a thermistor without a data sheet it can be difficult to get the resistance at 25C, so would be nice to have some flexibility on this parameter.

      I don't know the internal code requirements, but alternatives might be specifying the Steinhart-Hart A parameter explicitly or passing the temperature for the resistance value given (perhaps with guidelines in the docs like 'in the range 10C-30C').

        I suggest you use the calculator at https://configurator.reprapfirmware.org/. The link to it is on the Heaters page.

          Ah, had not found the one linked off that page which interpolates the 25C result. Thanks!
