E3D V6 Thermistor inaccurate reason new Firmware?
-
Hi Guys,
i'am not quiet shure what i exactly changed, but the Thermistor of my e3D V6 https://e3d-online.com/thermistor-cartridge got really big Problems
to get to Temparture. (260°C)
I belive before i updated my Firmware this wasn't the Case.I checked my Thermistor Settings and commented out the old Setting and tryed this Settings:
[[language]] M305 P1 T100000 B4267 C0 R4700 ; Set thermistor + ADC parameters for heater 1 Nozzle ;M305 P1 T100000 B4725 C7.060000e-8 R4700 ; Set thermistor + ADC parameters for heater 1 Nozzle ```The Values for the [http://reprap.org/wiki/Thermistor#ATC_Semitec_104GT-2](http://reprap.org/wiki/Thermistor#ATC_Semitec_104GT-2) The new Values should work and are the right one right?

The values you have commented out should give good results, assuming the thermistor you are using has the same characteristics as the 104GT-2. I have just set those parameters on a Duet and connected a 100 ohm resistor in place of the thermistor to test the reading from 1.19 firmware. The reading I get (286.4C) agrees well with the resistance vs. temperature table at http://www.atcsemitec.co.uk/gt-2-glass-thermistors.html.

Ok, thx i will try something today and hope that works. (Replace my PSU for the DuetWifi that got only 4A on 12V)
