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.
