Extruder heat creep issue
-
Hi,
I have build newly a Voron 2.4. But I am repeatedly meeting with heat creep issue in direct drive system. Fan is blowing more than enough to cool.
My configuration was using interpolation for all stepper motors. But I have read that turning of interpolation for extruder could eliminate the issue. What do you think? If interpolation needs to be turned off, what do you suggest as value (x64, etc...)
Hotend is standard E3D V6. As a last step, if I can not resolve I will change hotend as well.

@aytact if it's a dragon hotend, especially the HF version, I wouldn't be surprised

I use Dragon hot ends on all my extruders and have never run into an issue where heat creep caused any issue. -
@aytact If the fan is blowing enough to cool then I think that there are two things to check.
First, is the air actually getting through the fins of the cold-end? Air has to have somewhere to go after it gets to the fins.
Second, what are your retraction settings? If there are lots of long retractions in a short time then you may be pulling molten plastic above the heatbreak.
