; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B5500 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M308 S2 P"e1temp" Y"thermistor" T100000 B5500 ; configure sensor 2 as thermistor on pin e1temp
M950 H2 C"e1heat" T2 ; create nozzle heater output on e1heat and map it to sensor 2
M307 H2 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M308 S3 P"duex.e2temp" Y"thermistor" T100000 B4725 ; configure sensor 3 as thermistor on pin duex.e2temp
M950 H3 C"duex.e2heat" T3 ; create nozzle heater output on duex.e2heat and map it to sensor 3
M307 H3 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
; RISCALDATORE CAMERA
M141 H4 ; il riscaldatore 4 è il riscaldatore della camera
M950 H4 C"duex.e3heat" T4 ; configura l'uscita per il riscaldamento della camera sull pin e della scheda duex
M308 S4 P"duex.e3temp" Y"thermistor" T100000 B5500 C7.06Ee-8 ; configure sensor 4 as thermistor on pin duex.e2temp
M301 H4 B1 ; utilizzare il controllo bang-bang per il riscaldatore della camera
You don't have any M143 commands in there to set the temp limits for the extruder heaters, so they would be set to the default.
Which sensor is showing 2000c?
How did you come up with the thermistor parameters?
