Hi
IT would appear my controller has stopped giving accurate readings. It was fine late wednesday afternoon when I printed my x belt tensioner.
I went to printer another part fro my printer all of a sudden the bed temperature and the hotend temperature are reading wayyyy off.
Therefore the extruder won't extrude even though the lcd says it's 190. It's no where near the temperature.
Apparently the bed is pernamently 80degress celcius even if it's stone cold to the touch.
The Hot end is 60 but I measured 1.33v which doesn't equal anoything like 60 degress on an ad8495 thermocouple amp.
I have tested the amp on a development board, it returns the correct temperature.
The analogue bed input appears to report a voltage even if I unplugged the thermistor, is that normal?
So my gut feeling is something has gone horribly wrong with the adc within the 2560.
Any ideas?
