Hello,
I am using an Aurora Z605 printer / Melzi board , worked fine for like a year.
Now everything is working fine except the heatbed temp reading
I can turn on the heat bed but it keeps warming -until I stop it-, temp is not changing it always shows 38 degree.
when I trun on the nozzle and heatbed is on or off, the heatbed temp is copying the nozzle temp, showing the same temp as the nozzle temp.
Tested the heatbed thermistor it is working fine.
Replaced the heatbed with another one, same problem appears
swaped the thermistor wires (nozzle-heatbed) temp shows correctly.
is this a defective board, firmware corrupt ?
