Auxiliary Part Cooling Fan Overkill?

Bambu Lab P1 Series
1

Hello! I’ve recently installed the P1P to P1S upgrade kit and was thinking that the Auxiliary Part Cooling Fan (APCF) is a bit overkill for basic filaments, such as PLA.

What are your settings with APCF? Are there any general rules to follow?

Turn it on and find out, its just air, also need to remember the only reason to enclose a P1P is for those “other” filaments that aren’t “basic” so your question is loaded so I’m wondering why you are asking something you know the answer to already

I have no idea why people say to not use aux fan for pla and only use it for advanced materials. I run dual aux fans at 50% for fast pla prints. All other material, I run it at 0 because I dont like warping.

Aux fans are the only reason vorons can do 5 minute PLA benchies

You forgot about setting up macros for the chamber so the “other” filaments come off the beds faster. See I can be helpful

Good idea on the macros. I havnt messed with that yet.

I think us P1P users say it’s not necessary because there has yet to be a model I couldn’t print on the stock P1P without the Aux fan or where I thought an Aux fan would show an additional benefit.

With that being said my P1P is now a converted P1S and a few of the prints that I let the machine do its thing with the Aux fan warped at the side where the Aux fan was. Re-tried those same prints with the Aux fan turned off and the print stuck to the bed like it should and came out clean.

That’s just my experience and after two or three larger prints warping I quit using the Aux fan with PLA completely like I was with the stock P1P.

No good. Not sure ive ever had a pla part warp. I forgot about the p1p though. No need, I agree. The sound would probably be insane too.

It seemed like a good idea so I bought it as an upgrade and have had buyer’s remorse ever since. I suspect there was a use-case at one time however, I have not found any scenario where the additional cooling provided a superior print that I couldn’t otherwise overcome via tuning my filament.

But as the saying goes, YMMV.

Macros? What am I missing? Are we talking about Bambu Studio or Prusa Slicer? Macros have been one of the more request feature and if I missed the announcement … well… please point me to it. I’d love to be able to author Macros.

Here’s a post on that as a request.
