    FLSUN Prusa i3 extruder won't heat past 125 degrees C aftyer..

    Hi guys..

    I did after a big meltdown of my nozzle and thermister change the ceramic heaterpin and thermister.
    start up again and the extruder heat up til 125 degree
    i did use 3 new heating elements 12 v 40 watt 3,6 ohm (al same)
    and i did test 2 NTC 100K

    so i pulling my hairs out

    even if i direct put 12 v to the element (without the board ) it stuck on 125 degrees
    drives me crazy!!

    annyone know what i can do?
