after update to 1.0.3 firmware , temp unstable


i have updated to the new firmware 1.0.3 , when im powering on bed heating , the temperature of bed and extruder swinging up and down 10 +- deg .

my board is azteeg x3
extruder PID - calibrated

the sensor ok , the wire connection is great .

i was looking around for the topic and didn't find any solution

help appreciated   :)

thank you 


  • Bed will never improve wing bang bang which is on if below and off if above set temp.

    Extruder with pid should not swing 10°C. Here you have either set wrong heat manager and are not using pid or calibration values are bad. Would need to see a temperature diagram with output to say more about it.
