I'm on a Huxley with a Melzi Ardentissimo, with a Reprap hotbed.
The sensor was working fine, it suddenly started to report off base value of around 200C.
Now each time it's powered on, the temperature is different, though always between 160 and 200.
A short-circuit might have provoke the problem.
Is there any way to reset or tune it's temperature measurement?
How can I check if the component is OK?
cheers
