// Generic Silicon Heat Pad with NTC 100K thermistor ( Beta 25/50 3950K)
//
// 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.
