Good Morning,
I just upgraded my printer with a heatbed. Included in the shipment was a 100k Thermistor with the following spec:
Manufacturer: Murata
Partno: NCP21WF104J03RA
Type: Thermistors - NTC
Resistance: 100 kOhms
Power Rating: 200 mW
Tolerance: 5 %
Termination Style: SMD/SMT
Operating Temperature Range: - 40 C to + 125 C
Current Rating: 0.1 mA
Unfortunately I didn't know which type I should choose in the Marlin firmware. Standard "1" is not working properly.
