Problem description
Hotend does not heat up or reach the temperature needed.
Symptoms
- Nozzle temperature value stays at ambient levels or can't reach the target value.
Diagnostic Steps
1. Check if the root cause is the thermistor or the heating element - heat the nozzle with a soldering iron or a heat gun - and see if the temperature readings increase.
2.
Repair Steps
1. Check to see if the part cooling fan / hotend cooling fan is blowing on the heater block and/or thermistor. If so, move fan duct or fan itself away from blowing on the heater block and/or thermistor.
2. You may need to perform a PID tune for your specific heater cartridge. You may also need to do so if you have re-flashed your motherboard or even if you've changed out your nozzle size/material. Refer to PID Tuning In 10 Easy Steps for steps on how to perform a PID tune of your hotend.
3. If your printer is giving you THERMAL RUNAWAY error messages, DO NOT CONTINUE TO PRINT! Verify that your thermistor is reading correctly by using a hair dryer to heat up the hotend. If that is reading correctly then you may need to change out your heater cartridge. If the thermistor is not reading correctly or is fluctuating greatly, you may need to either perform a PID tune of the hotend or change out your thermistor for a functional one.
