SV06 - Bed Heating Error

My SV06 is a few months old and now it will not heat the bed, it shows “???” were the current bed temp should be.

Hi @salsa Sorry to read about the matter. Hope the suggestions from engineer might help you resolve the issue.

  1. Unplug the thermistor from the heated bed and see what temperature is displayed.
  2. Swap the thermistors between the nozzle and the heated bed and see what is displayed.

If the value displayed is abnormal, could you pls add a pic for further lookup? Let me know if you need any further assistance.

Hi @sovol3d, I have a similar issue. This is what the temperature display shows:

I swapped the nozzle and bed thermistor wires and the “err” is shown under nozzle temp instead.
