Replacing Nozzle Thermistor: Raise3D Pro 3 Printer Guide
Replacing the nozzle thermistor on your Raise3D Pro 3 printer involves a few steps. Here’s a detailed guide to help you through the process:
Unload Filament:
Start by unloading the filament from the extruder where the nozzle needs replacement.
Click “Utilities” on the screen to enter the printer control page.
Set the temperature of the nozzle to the proper unloading temperature (e.g., 215°C for Raise3D Premium PLA filament).
Click “Unload” to begin the unloading process.
Pull out the filament guide tube from the extruder.
Gently remove the filament from the extruder.
Adjust Position:
Disable the motor in the “Utilities” page.
Manually move the extruder to a suitable position.
Adjust the height of the build plate as needed.
Remove Old Nozzle:
Heat the left nozzle to 180°C-200°C.
Turn off the printer power.
Loosen the 4 screws on the model cooling fan and move the fan away.
Hold the heating block with needle-nose pliers to prevent movement.
Cover the left nozzle with an 8mm sleeve and turn it clockwise to loosen the nozzle.
Replace Thermistor:
Loosen the two screws holding the wires for the thermocouple being replaced.
Remove the retaining screws from the wire protection and take off the cover.
Cut the zip ties holding the wires.
Pull out the thermocouple wire from the extruder carrier.
Remember that replacing nozzles can be complicated, so follow the instructions carefully to avoid filament leakage during printing. If you encounter any issues, consider reaching out to Raise3D’s support center for further assistance.
Locating the Thermistor on Raise3D Pro 3D Printer
To locate the thermistor on your Raise3D Pro 3 printer, follow these steps:
Power off the printer and unplug it from the power source.
Remove the nozzle cover by unscrewing the two screws and gently lifting it off.
Identify the small, cylindrical sensor on the hotend. This is the thermistor.
To remove the thermistor, use a wrench or pliers to unscrew it from the hotend carefully.
Remember to handle the hotend components with caution, as they can become very hot during operation. If you need further guidance, you can refer to the official Raise3D support center for detailed instructions

Understanding Thermistors in 3D Printers
A thermistor is a crucial component in FDM (Fused Deposition Modeling) 3D printers. Let’s delve into its role and understand how to handle it properly:
What Does a Thermistor Do in a 3D Printer?
A thermistor is an electrical device whose resistance varies with temperature. There are two types:
Negative Temperature Coefficient (NTC) Thermistors: Their resistance decreases as temperature rises.
Positive Temperature Coefficient (PTC) Thermistors: Their resistance increases with higher temperatures.
In 3D printers, thermistors serve as temperature sensors. They are found in temperature-sensitive areas like the hot end and the heated bed. Their job is to monitor the temperature and relay data back to the printer’s micro-controller.
The micro-controller uses this feedback to control the print temperature and maintain it within the desired range.
Replacing and Attaching a Thermistor to a 3D Printer:
Caution: Thermistors are fragile, so handle them carefully.
Hot End Thermistor Replacement:
Detach the hot end from the printer.
Expose the thermistor by removing its insulation.
Carefully extract the old thermistor.
Substitute it with the new one.
Print Bed Thermistor Replacement:
Remove the print bed.
Expose the thermistor.
Replace it following the same steps as for the hot end.
Checking the Resistance of a Temperature Sensor:
Use a multimeter to measure the resistance of the thermistor.
Compare the reading with the expected value for your specific thermistor type.
Calibrating Your 3D Printer Thermistor:
Calibration ensures accurate temperature readings.
Follow your printer’s manual or online guides to calibrate the thermistor.
Signs of a Bad Thermistor:
Thermal Runaway: If the thermistor fails, the printer may not regulate temperature correctly.
Higher Than Usual Print Temperatures: Unexpectedly high temperatures during printing could indicate a faulty thermistor.
Recommended Thermistor Replacements:

Installing a 3D printer thermistor
Let’s delve into the proper installation of a 3D printer thermistor. Thermistors play a crucial role in maintaining accurate temperatures during 3D printing. Here are the steps for replacing and attaching a thermistor:
Understanding Thermistors:
What is a Thermistor? A thermistor is an electrical device whose resistance varies with temperature. In 3D printers, they serve as temperature sensors.
There are two main types of thermistors:
Negative Temperature Coefficient (NTC) Thermistors: Their resistance decreases as the temperature rises.
Positive Temperature Coefficient (PTC) Thermistors: Their resistance increases with higher temperatures.
Locating Thermistors in Your 3D Printer:
Thermistors are typically found in temperature-sensitive areas:
Hot End: Monitors the nozzle temperature.
Heated Bed: Monitors the bed temperature.
Replacing the Thermistor:
Hot End Thermistor:
Disconnect your printer from power.
Remove any fan shrouds or covers around the hot end.
Carefully remove the old thermistor (usually attached to the heater block) using a tweezer or similar tool.
Insert the new thermistor into the same location, ensuring a snug fit.
Connect the wires from the new thermistor to the existing wiring, matching polarity and color coding.
Reattach any removed fan shrouds or covers.
Print Bed Thermistor:
Similar steps apply for the print bed thermistor.
Locate the thermistor near the heated bed.
Replace it following the same procedure.
Calibrating Your Thermistor:
After installation, calibrate the thermistor to ensure accurate temperature readings.
Use your printer’s settings or firmware to adjust the temperature offset if necessary.
Checking Thermistor Resistance:
If you suspect a faulty thermistor, measure its resistance using a multimeter.
Compare the reading to the expected value (usually specified by the manufacturer).
Signs of a Bad Thermistor:
Thermal Runaway: Unexpected temperature spikes.
Higher Than Usual Print Temperatures: If your printer consistently requires higher temperatures than usual, the thermistor might be faulty.
Recommended Thermistors:
Consider these replacements:
HICTOP 100K ohm NTC 3950 Thermistors
Creality 3D Printer NTC Thermistor Temp Sensor.
