Is there any way to compensate for bed thermistor error?

Marlin BF 2.1.2

Hi, I have a 300mm bed that runs mains voltage. I decided to run a temperature test on the printers and this one is off by about 12% low. I am using the bed-OEM recommended Marlin number 11 thermistor.

It is virtually impossible to replace the thermistor in the bed, so I am wondering if there is a temp-offset in Marlin somewhere that I can set for a 12% increase.

I know I can adjust the temp in the slicer so that 60 becomes 72, but I use the same profiles for other printers and would like to have the offending one carry the error adjustment.

Possible?

Thanks

The only method I can think of is to modify the thermistor_11.h file in Marlin/source/module/thermistor. The last column in the file is the temperature reported for each ADC reading.

OK, thanks, I will check that out. Sounds like it might do what I want. If not exactly, I might be able to get it down to a reasonable 1% or 2% error.

Yow, that looks too hard. I selected another profile #75 and it is perfect. Thanks anyway.
