Name: 3D printer NTC thermistor 100K
We have many Ramp1.4 Marlin firmware, the firmware to run correctly, first go to the configuration parameters in the Configuration.h file.
In addition to the motherboard configuration:
#define MOTHERBOARD 33
Many beginners often forget the configuration parameters of thermistor, not normally result in measured temperature thermistor configuration parameters are as follows:
#define TEMP_SENSOR_0 / / 3 to set to 3, this is the first printing head
#define TEMP_SENSOR_1 0 / / this is a second printing head thermistor configuration, if not set to 0, if set to 3
#define TEMP_SENSOR_2 0 / / this is a third printing head thermistor configuration, if not set to 0, if set to 3
#define TEMP_SENSOR_BED / / 3 heating bed.
