fan cool N2 dual

Postby duke666 » Wed Apr 17, 2019 6:01 pm

В инструкции к слайсеру увидел вот такое расположение вентилятора для охлаждения детали, где я могу скачать такой обдув и какой там используется вентилятор?

#1 the slicer already natively includes layer cooling fan control commands- important difference- know an extruder cooling fan VS a layer print cooling fan. The extruder cooling fan cools the cold end heatsink of the extruder hotted system to prevent the heat from conducting though the rest of the system, and the layer cooling fan blows at the layer previously printed.

#2 that is the 50mm x 10mm fan and standard duct specific to a single extruder variant. You are asking for a dual in your title.

Sorry if I left someone's favorite fan or mod duct off, just a list I compiled quickly.

Спасибо за ссылки полезные, уже находил и напечатал ранее обдув для детали, подключил управление в управляемый слот, всё работает хорошо. Просто в 100% случаев второй экструдер и шаговый двигатель сняты, так как не использую и решил напечатать другой обдув более удобный как мне кажется был на фотографии инструкции.

Unfortunately, the only blower assembly I ever used on my N1 is the stock single extruder variant.
I will say this, the N1 has limited clearance as the entire extruder head approaches the corners of the frame- as compared to N2 and N2 plus models.

Sorry, I know that's not a very encouraging answer, but that's all I got.

That's okay, just wondered if you had tried it.

In your experience does an additional layer blower give any, some or a lot of improvement over the stock combo hot end airflow diverters? You are right about the reduced space in the N1 and I'm just trying to gauge whether it's worth the effort to try and squeeze one in.

Definitely, all the layer cooling you can get is better than stock.
Overhang performance is greatly improved as is general print quality is ways you might not first believe or understand that lack of cooling has caused you in the past.

Which is why:
My N1 has had the sides and door and lid removed the day I got it and never installed back since.
I quickly converted to a single extruder and single extruder style additional layer cooling fan.
I've looked at even better improvements like the E3D V6 hotend mod, and that coupled with the Berd air cooler mod.

Thanks Jetguy

Because of the limited space in the N1, the Berd cooler approach may be the only option. It would need to be a very quiet pump though!
