        <title>Bed temperature is hopping</title>
        <description> Hello,

if I try to heat my bed the temperature is irregular. Also if the temperature is reached it is changing by some degrees. Where I have to look for the fault? I use a silicone heater with builtin thermistor. Duet 0.6 from Replikeo.

            <description><![CDATA[ I exchanged the bed heater completely but the problem still persists. So it seems that there is a problem with the Duet? Is it possible that the two pins from the sockets of the heater and the Thermistor may be connected? Next time when I remove the bed I will test it.]]></description>

            <description><![CDATA[ Like causes are a bad connection in the thermistor wiring, or a short between the ground side of the thermistor and another ground.]]></description>
