When we use PT100 sensor without amp; set the thermistor table to 147 in Marlin, the temperature offsets are about 15 to 20 degrees C.
Changing the RUp in the PtLine equations from 4700 to 5025 seems to have addressed this issue on the low end of the scale.
However, at the high end of the scale, compared to a PT100 with an amp and using table 20, the difference becomes about 30 degrees C
Is this an issue with the hardware or Marlin?
