Temprature gain

Hi Repetier....
Thanx for the GREAT SOFTWARE!!!
Question directly to you...can you guide me with the bug fix on temp gain in the firmware. I have tried uploading the newest firmware but no difference.  I have the old problem of temp_gain enabeled giving the bed temp to be 0.0.  the rest is working perfect on the extruders.  If I disable temp_gain all is normal.  guide me into extruder cpp if that is where the bug fix lies.

Your help is greatly appreciated.

    Assuming repetier firmware in extruder.cpp function void TemperatureController::updateCurrentTemperature()  at the end the temperatur is corrected.
    #if ENABLED(TEMP_GAIN)
    currentTemperatureC = currentTemperatureC * tempGain + tempBias;

    So if it is always 0 you have tempGain and tempBias for that heater 0.

    There is no mean to set it for bed. In eeprom.cpp in void EEPROM::restoreEEPROMSettingsFromConfiguration() you have the initalization in case you reset it from config:

    #if ENABLED(TEMP_GAIN)
    heatedBedController.tempGain = 1.0;
    heatedBedController.tempBias = 0.0;
    #endif

    But you should also see it in eeprom due to this:

    #if ENABLED(TEMP_GAIN)
    writeFloat(EPR_HEATED_BED_GAIN, PSTR("Bed Temp. Gain"), 4);
    writeFloat(EPR_HEATED_BED_BIAS, PSTR("Bed Temp. Bias [degC]"), 4);

    I can only say danke.  It is beautifull now.
