nozzle not heating
H i there
i've got a Creality 10S PRO for some reasons the nozzle do not longer heat I changed it twice.
On the display it says the temp is -19°C and sometimes -15°C doesn't make sens.
Checked on the new brand hot end (I bought and got today) the voltage : it was 0V therefore I think the problem is coming from elsewhere. The bed Temp is OK.
Anything I can check before moving to change all the electronics ? or may be move to another brand ?
Thx in advance.
