Hi

i have breake the cable of my thermistor

but i have a new pne here:

specs:

NTC-Thermistor 100 K 3950

Thermistor Cartridge:
Size: 1.25mmx2.0mm glass bead
High accuracy: 1%
Resistance value at 25°C=100K
Wiring length: 1m / 39.3"
Operating temperature range: -40 ° C + 300 ° C
Rated power: 45MW

how i set it in my config.g ?

i have it like this :

M308 S1 P"e0temp" Y"thermistor" T100000 B3950 ; 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
M143 H1 S300 								   ; set temperature limit for heater 1 to 300C
M307 H1 B0 S1.00

is it ok ?

Veti

@lui2004

yes

B3950 thermistors are bit hit and miss.
Do not assume that when you are setting your temperature to 200C now that its the same temperature as before.

i personally use a pt1000 but i dont think they exist in the glass bulb that you want.

@Veti

last question

i change the thermistor,which is a good heater cartridge for my Ender 5 ?

Veti

@lui2004

@Veti

i have strange temperature printing pla with 250°C or is it the thermistor that make problems ?

Veti

what do you mean strange temperature.

pla does not normally need 250c to print

lui2004

i know, usually i print with 200-205°C

you think is a thermistor problem or i need a new heater cartridge ?

i have remake pid tuning ,still the same i can print pla only with min. 250°C

pid tuning does not change the reported temperature.

this is an indication of a wrong configuration.

which thermistor are you using at the moment and what is your config line for it?

I have this :

M308 S1 P"e0temp" Y"thermistor" T100000 B3950 ; 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
