what is the standard thermistor? hi,
we ordered our thermistor from [store.rrrf.org], so (i think) it's the Vishay 01T1002FP. is this the "standard thermistor" mentioned on pages like [reprap.org] ? we did some measurements yesterday, and the beta and rz values we calculated are quite different from the ones given on that page (3480, 29K), but seem to produce considerably closer to reality.
so basically, does anyone have the official beta/rz values for the 01T1002FP?

according to the datasheet, it is 10k Ohms at 25 degC, and 1990 Ohms at 70 degC. plugging this into the formulas on MeasuringThermistorBeta, gives beta 3671 and Rz 30857. then plugging this in to the calculator on ExtruderIO gives 0.014uF as the ideal capacitor (which is almost what we have at the moment, 0.01uF).

i haven't been able to test how it behaves with these "official" values yet.. i'm not in the same country as the extruder at the moment ;)
