Issue with AD8495 (Type 61) Thermocouple Temp Table
I'm in the process of building a new printer and I've run into an issue with the extruder temperature sensor displaying the wrong temp.
My setup is as follows:
Repetier Firmware: v1.0.1dev
Arduino DUE R3e (genuine)
Adafruit AD8495 Thermocouple amplifier - https://www.adafruit.com/product/1778
Type-K Insulated Thermocouple - https://www.adafruit.com/product/3245
I've wired the AD8495 up to the AUX ADC pins on the RADDS board (3.3v - ADC - GND) and verified that everything is working. When i check the temperature, it is showing as 256°C on the printers LCD display. I've tried swapping out the AD8495 and the thermocouple and every time I get around the same reading. I tried manually heating and cooling the thermocouple and verified that the temp displayed rose and fell accordingly.
After much head scratching, I happened to notice that the enclosure temp display in Octopi was sitting at 25.6°C.
It would appear that the temp table for Type 61 thermocouple is off by one full decimal place. Anyone have any ideas on how to correct?
