Thermal runaway when power on

3D Printing Asked on August 26, 2021

I get the error "Thermal runaway on E1. Reset printer." today on my Tevo Tarantula when powering on the printer. The display shows the error and the speaker beeps loudly everytime I power on the printer or reset it.

I use the firmware
https://github.com/JimBrown/MarlinTarantula, because I can switch E0 heat nozzle to E1 wires, without soldering; PID’s for nozzle were configured, and works fine before I replaced the power supply.

Recently my power supply was broken, and today I installed new power supply, clean nozzle, several times start bed leveling, and on fourth time of homing error appeared.

Power supply voltage tested with a multimeter and the voltage of power supply is 12.06V.

Note: several times printer started bed leveling.

Issue is solved!

Root cause was a broken thermistor circuit at board and broken thermistor.

I disconnected all wires and power, measured board and thermistors resistance: E0 = ~120 Ω, (E1 and Bed) = ~700 Ω. I swapped pins for TEMP_0_PIN and TEMP_1_PIN within Marlin for Tevo firmware at pins_RAMPS.h as described in answer on question Change hotend thermistor input in Marlin, changed thermistor and everything prints fine.
