In Configuration.h and in thermistortables.h it is listed that thermistor table # 8 can be used for a
thermistor like Vishay NTCS0603E3104FXT with a 4.7k pullup resistor.
NTCS0603E3104FXT is a 100 kOhm thermistor with beta_25/85 = 4100K according to this components datasheet.

This seems to be wrong: Table 8 cannot not linearize this combination of thermistor and pullup.
Table 8 seems to be for a 100 kOhm thermistor with beta_25/85 = 3950K using 10 kOhm pullup resistor.

@DanieleSdei — Would you care to comment on this? This particular table seems to have come from the RepRapPro Huxley fork of Marlin.

Thermistor 12 seems to be an alternative table for E3104FXT calibrated for Makibox. Possibly it's closer to the correct values.
