We’ll delve into each of these potential problems in detail, providing step-by-step troubleshooting guides and solutions to get your Tevo Tarantula back in working order.
Faulty Thermistor
The thermistor is a crucial component responsible for measuring the hotend’s temperature. If the thermistor is damaged or has come loose, the printer won’t be able to accurately read the temperature, leading to the E1 error. A damaged thermistor will often present with erratic temperature readings or display a constant, incorrect temperature. Inspecting and testing the thermistor is essential to rule it out as the source of the problem and will save you a lot of time troubleshooting other parts of your printer.
Testing the Thermistor
Testing the thermistor requires a multimeter set to measure resistance (Ohms). Disconnect the thermistor wires from the mainboard. At room temperature, the thermistor should have a specific resistance value, usually around 100k Ohms for most 3D printers, but this can vary. Consult your printer’s specifications or the thermistor’s datasheet for the correct value. As you heat the thermistor (e.g., with a heat gun or by holding it gently), the resistance should decrease smoothly. If the resistance reading is significantly off, unstable, or doesn’t change, the thermistor is likely faulty. Also inspect the wires and connections of the thermistor for any damage.
Replacing the Thermistor
If the thermistor is faulty, replacement is necessary. Disconnect the old thermistor wires from the mainboard and the hotend. Carefully remove the old thermistor, noting how it’s mounted. Install the new thermistor, ensuring it’s securely in place within the hotend block. Reconnect the wires to the mainboard, making sure to match the polarity if applicable. After replacement, ensure the new thermistor’s resistance matches the specifications for your printer. Check the temperature readings on your printer’s control panel after the replacement to confirm the issue has been resolved. A new thermistor is relatively inexpensive and will quickly get you back to printing.
Issues with the Heating Cartridge
The heating cartridge provides the heat for melting the filament. If this component fails, the hotend won’t reach the desired temperature. Heating cartridges can burn out, develop internal shorts, or their connections can become loose. A malfunctioning heating cartridge is a common cause of the E1 error. Identifying this issue is crucial for a swift resolution, as this may be the source of your problem. Check the heating cartridge for any physical damage like cracks or fraying wires.
Testing the Heating Cartridge
Use a multimeter to test the heating cartridge. Disconnect the heating cartridge wires from the mainboard. Set your multimeter to measure resistance (Ohms). Measure the resistance across the cartridge’s terminals. The resistance should be a specific value, typically between a few Ohms to several tens of Ohms, depending on the cartridge’s voltage and wattage. Consult the cartridge’s specifications to determine the correct resistance. If the resistance reading is significantly off, open circuit (infinite resistance), or short circuit (zero resistance), the heating cartridge is likely defective. Also check the wires and connections for damage.
Replacing the Heating Cartridge
Replacing the heating cartridge involves disconnecting the old cartridge from the mainboard and the hotend. Carefully remove the old cartridge from its housing, noting how it is mounted. Install the new cartridge, ensuring it’s securely mounted within the hotend block. Reconnect the wires to the mainboard, being mindful of the polarity. Once the new cartridge is installed, test the printer by heating the hotend to ensure it reaches the correct temperature. If it still fails, recheck the connections and consult your printer’s documentation or online resources for further troubleshooting. A new heating cartridge is an easy replacement that often solves the E1 error.
Problems with the Power Supply
The power supply unit (PSU) delivers the necessary voltage to the heating cartridge. If the PSU isn’t providing enough power, the hotend won’t reach the required temperature, which can trigger the E1 error. PSU failures can occur over time, often due to component degradation, power surges, or overloading. Inspecting the PSU is therefore an important step in troubleshooting this common problem. A malfunctioning power supply can affect not only the heating cartridge but also other components on the printer.
Checking the Power Supply Voltage
Use a multimeter to check the output voltage of the power supply. With the printer turned on, measure the DC voltage across the power supply terminals. The voltage should match the specifications of your printer, typically 12V or 24V. Consult your printer’s manual or the power supply label for the correct voltage. If the voltage is significantly lower than the specified value, the power supply may be faulty and should be replaced. Ensure the PSU is plugged into a properly grounded outlet. Check for any visible signs of damage such as bulging capacitors or burned components on the PSU.
Replacing the Power Supply
If the power supply is found to be faulty, replace it with a new one that matches the specifications of your printer. Disconnect the old PSU, carefully noting the wiring connections to the mainboard and other components. Install the new PSU, connecting the wires correctly. Double-check all connections to ensure they are secure. After replacing the PSU, test the printer by turning it on and attempting to heat the hotend to the target temperature. If the E1 error persists, continue troubleshooting other potential causes. Choose a reputable brand for the power supply to ensure reliability and safety.
Wiring and Connection Issues
Loose or damaged wiring and connections between the mainboard, thermistor, and heating cartridge can interrupt the flow of power and data, leading to the E1 heating failed error. Vibrations during printing and general wear and tear can cause these connections to loosen over time. A simple inspection of the wiring can often reveal the problem. Also, damaged wires can cause shorts or open circuits, which also will lead to issues.
Inspecting Wiring and Connectors
Carefully inspect all wiring and connectors associated with the hotend, thermistor, and heating cartridge. Look for any signs of damage such as frayed wires, broken insulation, or loose connections. Check the connectors on the mainboard, ensuring they are securely plugged in. Examine the crimps on the wires for corrosion or damage. Gently tug on each wire to check for secure connections. A visual inspection can reveal a lot about your wiring.
Recrimping or Replacing Connectors
If you find loose or damaged connectors, recrimp the wires or replace the connectors. Use a proper crimping tool to ensure a secure connection. If the wires are frayed or damaged, cut off the damaged section and strip the wire ends before recrimping or inserting them into a new connector. When replacing connectors, make sure the connections are correct. If you are not comfortable with electrical work, it’s best to seek help from someone experienced with 3D printers.
