Hi i got my E3D v6 now and assembled everything like its described here.

http://wiki.e3d-online.com/index.php?title=E3D-v6_Assembly#Repetier

But the last part of the tutorial confused me a bit it says:

[quote]Repetier

Use thermistor definition number 8:

#define EXT0_TEMPSENSOR_TYPE 8

Or select “ATC Semitec 104-GT2” if using the Online Configuration Tool (v091)

For safety it is strongly recommended to do the following:

Limit the Max PWM value (EXT0_PID_MAX xxx in the config file) to ensure that current is limited to a safe value.
Set the Minimum defect temperature to ensure that the thermistor shorting out is caught by the firmware.

New in Online Configuration Tool (v092) are the two options to also improve safety:

Decouple hold variance and Decouple min temp. rise to detect the thermistor coming loose. These must be set appropriately for your system to ensure that they work properly.

Upload the new firmware to your electronics. [/quote]

So where exactly do i need to add this EXT0_TEMPSENSOR_TYPE 8?

Is it even necessary to do this? I mean i tried to heat my hotend and controlled the temperature and it worked great.

That’s quit confusing.

AFAIK the E3D v6 comes with the same thermistor type as the stock velleman extruder, thus being type 5 in marlin.
So you shouldn’t need to change it.

But it may be possible that they ship different thermistor types based on availability.
What does your part list from E3D tell you about the thermistor?

Oops!

I just looked at the manual.
It says use thermistor typ 8 in REPETIER.

Do you use Repetier Firmware or marlin?

In Marlin it is type 5, just as the manual says a few lines above :

[quote]Marlin

Reconfigure your firmware for the Semitec 104GT2 thermistor: In configuration.h:

#define TEMP_SENSOR_0 5[/quote]

Well, yes i use repetier.

You mean repetier host or repetier firmware?

The stock firmware for the k8200 is marlin.

If you really use repetier firmware i’m out of business, cause i use marlin.

6

No i mean i am using repetier host, the program to print things. I never changed anything in the firmware ever.

Then you are good to go.
As the thermistor used by the k8200 marlin branch is actually the same type as the E3D v6 comes with.
