|
|
* Many generic silicone heat pads use the MGB18-104F39050L32 thermistor, applicable to various
|
|
* wattages and voltages. This table is correct if this part is used. It's been optimized
|
|
* to provide good granularity in the 60-110C range, good for PLA and ABS. For higher temperature
|
|
* filament (e.g., nylon) uncomment HIGH_TEMP_RANGE_75 for increased accuracy. If higher
|
|
* temperatures aren't used it can improve performance slightly to leave it commented out.
