PWM Extractor Fan Speed Controller for 3D Printer Enclosure - Tukkari, PrusaBox, Lack Enclosure

foreign [Music] ERS welcome to today's video and today I'm going to be looking at pwm controllers for your enclosure extractor so I've got one here I've had quite a few questions when I've been talking about extract fans fitting them to enclosures if you've seen my previous videos you've seen that I made a temperature controller with a Raspberry Pi not that they're connected the temperature control is completely independent but after making that video some people are asking what about uh a progressive fan controller so I've picked up this one uh this was from Amazon and at the end of the video I'll give you details of the one I've got there are a variety I picked this one for two reasons the shape is just what I need a rectangular shaped to fit in my current unit and also reading the write-ups it was quite easy to configure some of the others seem to be a bit more complex so let's have a look and see what we've got so just looking at the pwm controller you've got the LED display and it comes with a temperature probe which has got a reasonable length of cable as well I've just quickly added the power supply here it's the 12 volt power supply going into it the other thing that you need to note is that it doesn't come with this particular plug and cable that I've got here that goes to the fan but I will give a link as to where you can get them from so first to pull that off you'll just have four pins on the board so you need to purchase the actual plug and pins so how does it work now with this one you set a stop temperature so anything below a certain temperature and the fans will not work then you set a start temperature where the fans will start turning and they start turning progressively up to the full temperature that you set so basically there's three temperatures stop a start and a full fan temperature this particular module also has an output one of the outputs here is to a relay relay coils that'll be 12 volt output a relay coil should you wish to turn off or on and any other device that's connected to a relay but that's not something I've covered also I haven't connected the output directly to my fan I've used a PC extension fan extension it's a has to be full cable and by the way your fans to work this all have to be four cable fans so it's just an extension that I've chopped off and wired up with the pins here I really don't want to do that to my doctor so so I've got a Nocturne fan here it's a full cable fan as we can hopefully see there the color code was slightly different on this third-party extension in fact uh one of one of the cables was yellow and the knock two was green that was the only difference but at least I can just connect them together and it will all work another thing you can do if you buy a splitter so I've got here I want two-way splitter I can actually activate two fans should you need to have two fans controlled at the same time and I know in my presser box with my Mark III I have got a small 40 millimeter cooling fan for the IT board and the main extractor there so I will be using two in that but with my Takara enclosure I'll only need the one main fan for the moment so let's get on and see how we set the temperatures so to set up the temperatures we've got three buttons here A plus a minus and an okay button so if I press and hold the OK button the low temperature so it starts with L that's the temperature that the fans will start to turn at the slowest speed so you can plus or minus that let's see if we can get it a little bit darker so you can see it a bit better there we go if you're happy with that then you press the OK button once more and that's the high temperature that's the temperature that the fans will actually go at full speed so plus or minus to set those and remember it's all degree C and finally the close temperature that's the temperature at which the fans will turn off and will not start up now one thing to bear in mind is that the start of the fan temperature and the full temperature must have a five degree difference and between start temperature and the closing or off temperature must be at least two degrees so now that we've set all three let's have a look and see how it works in practice so we have the probe we have some extremely warm water that's probably a bit too hot and we have some cold water we have two fans a 40 millimeter let's turn that around a bit and a 120 so the closing temperature was about 22 but I think the start temperature was about 25 so if I just dabble it in there a little bit there we go the starting straight away but it's not full power [Music] and that's two four two two six zero so 2200 RPM 26 degrees and you can see it's going down on the RPM as well as the temperature is decreasing but if I put this in a little bit more it'll probably go straight up to the maximum there we go and you can see and probably here that the fans have gone up to the maximum pop them in some cold water and you can hear it as it cools down the temperature decreases now those fans will carry on spinning until it gets down to 22 degrees which was the stop temperature I hope that shows you how the pwm controller works so that's a brief demonstration of how the pwm motor controller works now I'm going to be fitting that into my or is this my previous controller enclosure so I've printed a new front that should just pop in if anyone wants the STL to this I'll include it in a link shortly uh so I think I'll be preferring this to the previous controller with having the facility to vary the speed right so if you liked this video uh please do a like and a subscribe I hope you really appreciated uh links to this as I mentioned will be in the description uh same with details of the fans I do recommend D not tour fans and also let me just lean over a little bit if you want details specifically on this controller they're not available generally on the Amazon description of this particular product but I have got the content here so I will provide a link somehow or I'll perhaps post it at the end of this video Page by page so you can understand exactly how to use it and configure it great well thank you very much again and look forward to seeing you again soon
