DuetWifi V1.01- Time for ADC Replacement?

[lasakro]

Yes they are still around and this thing is built like a brick out house. Been going like 5 years. In the past couple of months, now I only drive it on weekends, feed is getting hard. Finally the only way I could get smooth PLA prints was to up the hot end temp gradually to 270 Deg C until it tripped on high temp. So the temp circuit has been drifting down. I don't have an IR measurement to confirm but it's pretty obvious. So I replace the thermistor and no change. So which chip should I go after for input E0? A link to a schematic would also help. Thanks for reading

ADC is in the main processor.

Great, that gives me some ideas. Thanks!

Does the E1 sensor input have the same problem?
