Temperature issue

Ender Series
1

Hi guys, I try to swap the hotend, I bought the new one by amazon but the printer doesn’t work, when i try to put the temperature at 150/200° this one crash. With the crash there is an allarm and a message like
“E1 failure

printer stopped

restart please “

idk how to do

and maybe the temperature to increase is a little bit slow, is it?

That error usually means the printer detects a problem with the hot end temperature sensor or heater after the replacement. On many Creality Ender printers, “E1 failure” or “Heating failed / printer halted” happens when:

  • the thermistor (temperature sensor) is disconnected or damaged

  • the heater cartridge wiring is loose

  • the new hot end uses incompatible wiring

  • the thermistor is shorted by the screw holding it

  • the firmware sees temperature changes that are too abnormal

Try these checks in order:

  1. Turn the printer completely OFF and unplug it.

  2. Check the thermistor wires

    • The thermistor is the tiny sensor in the hot end with very thin wires.

    • Make sure the wires are not broken or pinched.

    • The retaining screw should be snug, not crushing the wires.

  3. Check the heater cartridge wires

    • These are the thicker red wires.

    • Make sure they are firmly connected to the motherboard terminals.

  4. Look at the temperature reading before heating
    Turn the printer on without heating:

    • If the nozzle temperature shows something crazy like -14°C, 0°C, or 300°C, the thermistor connection is bad.

    • A normal idle reading is usually around room temperature (20–30°C).

  5. Verify the connector placement on the motherboard
    Sometimes during replacement, the hot end fan / thermistor / heater connectors get swapped.

  6. Run a PID autotune (if the wiring looks correct)
    New hot ends sometimes heat differently and need tuning.

    For Marlin firmware:

    M303 E0 S200 C8

    Then save:

    M500

  7. Important compatibility issue
    Some cheap “Ender-compatible” Amazon hot ends use:

    • different thermistors

    • different heater resistance

    • incorrect cartridge voltage (12V vs 24V)

    If your printer is 24V and the hot end is 12V, heating behavior can fail quickly.

The most useful clue is:

  • What temperature does the printer display before heating?

  • Does it rise normally for a few seconds before the error?

  • Which exact Ender model do you have? (Ender 3, V2, S1, etc.)

Hope this helps.

HI Mac, first of all thank you for the interesting in my problem and thank you for helping me!
I have an elder 3 custom, so i saw that the motherboard is custom (the MOBA is BIGTREETECH BTT SKR Mini) and probably also any other parts but I’m not really sure cuz I’m new in this world.

I fixed the problem btw.
it was the heater resistance idk why, but the new one (24V 40 W didn’t heat up well).

So i put the old one and now it seems to work.

great news, the great thing about amazon is you can return anything.
