Cooling fan nozzle abs

Hi

Thanks
Gary

Have you got cooling on? A lot of people say don't use fan with ABS. A lot of people also don't know what they are talking about. 😀

Topic starter, if you do not give info, then nobody can help you.
Pictures and what is wrong?
What did you try?

if you do use a cooling fan on abs, then you get a not strong part, abs is normally no cooling fan.

Temps, try different settings.
Speed, slow down, a little bit, 75%.
Try different abs.

Incorrect. You can get a very strong part with cooling. I do it all the time. Just make sure it's extruded hot enough to fully melt to the previous layer.

I have added a new file for BMG extruder with a nozzle support that should fit better.
The extruder files that I started from I found on Bondtech's website, but they were not the right ones.
After a tip I found the right extruder files on Github.
