Error #2:4 hotend heater failure

Since this morning, we are having a problem with heatend. it says Error “#2:4 hotend heater failure. temp not raised at ct 3, mt4, tc30000”

We tried disassemble headend and put back together. Tried to buy new heater cartridge and thermistor but no available ones in recent days.
Pls help.


Hi,
Please replace the heater in your printer. Additionally, check the extruder cable (make sure the filament stepper motor is not skipping) and the PCB board.

To purchase a new heater, please contact support@zortrax.com via email.
