In case anyone is interested. I took the temp vs. resistance values Alirubber gave me for the Herculien heated bed (100k thermistor, 3950 beta value) and fit it to the Steinhart-Hart Equation. The values for the A, B, and C coefficients come out to ~ 0.0006454337947, 0.0002239473005, and 0.000000087, respectively.
This is implemented in the smoothie config file by commenting out the line for beta value (if that’s what you were previously using) to look as such:
and adding the following line:
This should allow for accurate temperature readings from 15-125C
