Frequently asked questions
What is the price of NTC 100K 3950 Thermistor Temperature Sensor for 3D Printers in Egypt?
NTC 100K 3950 Thermistor Temperature Sensor for 3D Printers currently costs 28.5 EGP in Egypt.
Where can I buy NTC 100K 3950 Thermistor Temperature Sensor for 3D Printers in Egypt?
NTC 100K 3950 Thermistor Temperature Sensor for 3D Printers is available from UGE. Compare the offers above to find the best price.
Why do I need to match the firmware thermistor type?
The firmware converts the resistance reading into temperature using a specific thermistor table. If the setting does not match a 100 kΩ, B 3950 NTC, the displayed temperature will be wrong.
How do I wire it to the printer board?
The thermistor is a two-wire component and its leads are connected across the board's thermistor input. The board's own pull-up resistor forms the voltage divider that the controller reads, so polarity does not matter.
