//===========================================================================
// Set this if you want to define the constants in the thermistor circuit
// and work out temperatures algebraically - added by AB.
// See [en.wikipedia.org]
// BETA is the B value
// RS is the value of the series resistor in ohms
// R_INF is R0.exp(-BETA/T0), where R0 is the thermistor resistance at T0 (T0 is in kelvin)
// Normally T0 is 298.15K (25 C). If you write that expression in brackets in the #define the compiler
// should compute it for you (i.e. it won't need to be calculated at run time).
// If the A->D converter has a range of 0..1023 and the measured voltage is V (between 0 and 1023)
// then the thermistor resistance, R = V.RS/(1023 - V)
// and the temperature, T = BETA/ln(R/R_INF)
// To get degrees celsius (instead of kelvin) add -273.15 to T
// This DOES assume that all extruders use the same thermistor type.

bilanciamist
respira e calmati, se già perdi la calma figurati al momento delle calibrazioni di fino.
nel caso in questione, nel tuo firmware sono attive solo queste definizioni:
#define BED_BETA 3988.0
#define BED_NTC 10000.0
#define E_BETA 4138.0
#define E_NTC 100000.0
perchè le altre sono inattive, dipende tutto dal comando #ifdef REPRAPPRO_MENDEL2, poichè la tua stampante è definita come #define REPRAPPRO_MENDEL2. Se le hanno messe devi lasciarle come stanno, semmai dovresti perdere un pò di tempo per dirci che stampante hai con precisione, e magari dove l'hai comprata.
Per capire se il modello selezionato nel firmware è giusto oppure no.
