      @klcjr89 Do you still wire the same? Need a diode for it?

        @mysta No flyback diode needed for the brushless pump. The pump has its control circuitry inside it. You can still PWM it and treat it like any normal fan, although low PWM values don't work well. I run it at 255 PWM, as there are certain audible ranges at various lower PWM values that are bothersome.

          @klcjr89 Nice, may grab one of those and use the other pump on one of my lesser used printers.

            Yep. I saw this one, but I thinks that it is extremely overpriced for its objective. And it is not so effective like pump from 'berd-air' solution.

            The head from berd's pump provide alot of air 13 l/min and I could not find anything similar in this overall dimensions. So I want to try this head with some brushless motor like A3650, instead of noisy brushed JRK-555.

              You must've not read the specifications correctly, as the flow rate is just as good as a 'berd-air' pump, otherwise I wouldn't have bought it. There is a 2 liter per min. difference in the reported Chinese specs for flow, and the berd-air is already overkill as is for flow rate. 🙂

                yep it is actually slightly higher O/P to the 555 ones mind mine are not that noisy

                Video of mine at various levels and you will note at the start that there is a fan that is very noisy and is about to be swapped out and it is my board cooling fan and if you listen carefully you can hear the air coming out of the tube above the sound of the pump at around the 50% level.

                  Indeed, it is not as noisy as it is spoken about.

                    If you're in the USA, I have an extra 24V brushless pump I could sell, but I do not have an extra set of mufflers.

                    I would be very interested in this. What would you be asking? Feel free to email me directly about it.

                          Hi, if you're building a delta, it depends if you've planned to use a smart effector or not.

                          With a smart effector the clearance is very limited, tusk system works well from the moment you put a fan that gives a good air pressure, but with the clearance it can be tricky. 2 blower oriented toward the head block with a sock on it did a better job but it's very space consuming.

                          A big blower on the effector then plastic tubing passing from above to under toward a tusk system would be the best. But there's nothing on thingiverse like that yet, I've made a prototype but never ended it or even tested it.

                          I've recently switched to a berdair system, the noise is not really a problem, but it's there.

                          Delta goes BrrrRRRRrrrrrRRRRrrr

                            Since I have no experience with the smart effector yet, could someone help me out for a sec?

                            What I want to do right now, is to use two fan designs from thingiverse, each of them use 1x 40mm fan, so I can use my Noctua fans here. What I wonder is if the two designs listed below + 2x 40mm fans will work on the smart effector, or if it will generate too much weight and interrupt the auto-calibration?

                            Part cooling
                            Effector cooling

                            I am really grateful for the discussions that happened in this thread, its all experiences that I try to absorb and incorporate into my ideas when improving my printer. Hope someone can give me a hint if the designs linked above has a chance of working. I haven't had the chance to print them yet, so I'm just trying to plan ahead.

                              No problemo. No enough weight to "wobble" the hotend to the point it'll engage false triggering. Even if it happens you can fine tune the trigger sensitivity of the smart effector.

                                  Either is more than enough for print cooling. I chose the parallel model for more flowrate, as the mufflers I bought reduce the flow rate. I have the mufflers installed in both the input and output for greater noise reduction.

                                  I hope these images help (the last image is the muffler specs).

                                    @klcjr89 Thanks, I think I'll go parallel too.

                                    What is the noise like generated by the air pump in use or parts cooling? I guess it runs at a relatively low PWM for this purpose....

                                      @benkay I would wait for @MSquared 's opinion first before you order anything, as he has a 24V parallel brushless pump on the way from me.

                                        Indeed I do.

                                        I am currently running a standard Berd-Air pump and have spent some time dialing it in so I plan on posting a comparison between the two in terms of performance, ease of install / mounting, and noise level once I get my hands on it!

                                        Stand by!
