RADDS with TEMP_GAIN 1 results to BED-Temp always 0.0
Hi,
just tried to install dev-version with the new TEMP_GAIN activated.
Result was, the Temperature-Reading for the Bed was always 0.0 Degrees and the Bed did not activate.
Looking in the Eeprom settings, there were new values for the extruder temp-gain and temp-bias but not for the bed.
Using a Radds board and the temp_1_pin for the heated_bed_sensor_pin.
The Extruder Temp Readings are okey.
Deactivated the temp_gain and compiled again = Bed works as it should.

for 1.0.4dev firmware. There you see it writes the bed values after bed PID values. It might not detect you enabling/disabling gain so eeprom gets not initialized unless you reset eeprom with
M502
M500
Were you using 1.0.3 firmware?
For the new config with temp_gain i was using another eeprom-config number so eeprom should have gotten initialized and for the hotend it did.
Maybe i will try to activate it again and flash the firmware again with M502 M500 and see if the new eeprom values are then there for the bed.
As for now, i was just curious about the feature but had no intention to use it. But was very baffled when the bed-sensor didn't work.
But i thought, if anyone else has this issue, i open an thread here.
After a M502 M500 Extr. 1 Temp Bias and Extr. 1 Temp. Gain is there, but no Bed Temp. Gain/Bias.
As long as i don't reset the board, Bed Temp is working. But after a poweroff/reset of the printer, no Bed Temp again.
