// R25 = 100 kOhm, beta25 = 4100 K, 4.7 kOhm pull-up,
// Generic Silicon Heat Pad with NTC 100K thermistor
//
// Many of the generic silicon heat pads use the MGB18-104F39050L32 Thermistor   It is used for various
// wattage and voltage heat pads.  This table is correct if this part is used.   It has been
// optimized to provide good granularity around the 60 C. and 110 C. which corrisponds to bed temperatures
// for PLA and ABS.  If you are printing higher temperature filament such as nylon you can uncomment
// the higher earlier entries in the table to give better accuracy.  But for speed reasons, if these
// temperatures are not going to be used, it is better to leave them commented out.
