Intermittent bed preheat error
Yesterday I ran a PETG print normally, then when I started another one, the printer reported a Bed Preheat Error and stopped. When I tried again a couple of hours later, the error recurred.
This morning I ran a self test, which was all normal. Then I tried a print again, and this time it completed normally.
The firmware was at 3.11.0, so I then updated it to the current version, 3.13.1.
The printer has never reported this error during years of use. Anything else I should look at? I don't see much point using a hair dryer to test the bed thermistor, since the heat functions are now working. Can this be a sign of gradual wear in the thermistor and/or heatbed?
