 All right, so I got my my hole Cut in my bucket here. I got a square hole because of this You got to put the plug through it and once again, it's the little Chinese Flat bladed no holes generic plug But they send to the US So the way this works though Get your water inlet connect to your pump. Oh and your pump lives down in your bucket And I've read about you can add any freeze if you're in cold climates you can add Algae side These Clorox bleach to shock things dead But mostly it seems to be You want to prevent algae from growing in your bucket or in your water system in general You need To remove light so have a closed bucket with opaque opaque size like this or Just add a lot of chemicals and I've opted for the opaque bucket cheap three bucks or bucks at home diva and And And I'll just be using distilled water Maybe once in a while. I'll add a little bit of bleach just to make sure things aren't growing in there but other than that this should be a pretty closed system and Hopefully things won't grow in it One of the other things people mention about these water systems is that you're a turn line So where the water goes back in you're gonna want to have that below the water line and the idea behind that is to Reduce the amount of air that you're introducing into your water So reduce the amount of air that you're letting in your water because algae and any little micro organisms that are gonna grow in your water and Muck it up. They also need dissolved oxygen so Removing that dissolved oxygen like the oxygen I think right now is Important for keeping your your algae growth under control And I've got six gallons here. I don't know if I'll need all six I don't think the tube takes a whole gallon of water, but we'll find out Now there's That's four, so I'm gonna try this out and just see Right now Put that in let me see if I can check in our laser tube Right there we go. We've got water going through take y'all try and the Air bubbles in there and the best Advice on that is just to tip the machine Because you're gonna have air bubbles no matter what you do And you're just gonna want to let this run for a while Then tip your machine so that the air can go out Back into your reservoir let that run for a while with the air bubbles purge I think eventually I'll probably get a flow meter Just so I can see because you can't really hear it it's under water It's under a lot of water inside that sealed bucket, so It's um It's pretty quiet closer Probably here my 3d prints are going more than this thing So anyway, it's a it's quiet so flow meter would be a good idea and a temperature gauge I don't know if eventually I mean it's pretty warm here in my garage This is gonna keep things at the correct temperature or not I don't know find out So the the tipping method seems to work well I mean the this machine is light enough where you can you can lift it up without any problems But you really do have to lift up quite a way in order to To get those air bubbles out and so you're really They're gonna need to get over here, so I don't know if you can see there's there's one right there So I tip it up and then Back and that seems To suck those things right out And there we go, so they're still See it's gone, but yeah Those will probably show up every once in a while as the The bubbles get sucked in through the pump Until we're out of bubbles, so I'll I'll keep an eye on that, but I'll just let this run and I plan on having this just plugged in I don't know if you can see my power strip over there, but that's going to be the power strip for this whole area When I'm not using the laser, I'll just flip that off the power for the pump will go off And when I want to use the laser or anything associated with it I'll flip it on that way the power will always be to the pump and it'll always be circulating through the laser And I hope I don't need a chiller, but Uh people have said that lasers like a cooler Not freezing, but cooler, so we'll see uh If that's required or not in my climate It just gets pretty warm in the summer. I thought that ambient temperature would be good Um To disperse the heat, but I did a test run and I don't have a piece here, but it didn't seem Very powerful Then I read online about the the cooling for these lasers and they tend to be happy around 18 degrees celsius So I wanted to find a cooling solution But one that wasn't super expensive because you can buy those coolers CW 3000 CW 5000 and they are Hundreds of dollars So I've already spent too much on this thing as it is Uh anyway, I went into Craigslist and I found somebody who had a Water cooler and water coolers have a compressor like your refrigerator and they've got lines and they've got a A coil So let me move this thing out of the way And in my bucket of water now I have a coil copper That is cooling the water down So I'll uh, I'll give you a shot of what Ambient is I'll just point this at the ground 27.8 Now if I uh, shoot the Inlet hose the water going to the to the laser tube 23.5 And that's a 74 So anyway Um, that's cooling the water down and hopefully that will work a little better than ambient temperature Because apparently higher temperatures Reduce the lifespan of the laser tube and give you lower power versus results So I want to get the most power I can I got this thing for 25 bucks. It had the water cooler exterior, but Stripped it all off until I got just the radiator compressor and the coolant lines and uh You'll see right there's my thermostat and it's got just a little screw on the back if uh, the water gets too cold and causes the tube to condense Maybe we're below the dew point then I can just back off on the thermostat Hopefully this will work out. I'll have to fix my bucket cut a hole right about there to uh Allow space for those those to fit in while being able to close the bucket completely So that's uh, a nice addition a cheap addition and maybe one other people can uh, can use Wanted to show one thing With the cooling system because I wasn't really happy with my my kind of makeshift We would set up there. So, uh, one thing you'll notice there's an extra hole on the machine now and that is my flow meter I've got the pump going right now and you can see the water's flowing I improved the the inlet and outlet I Changed out the tubing for some of this uh thicker vinyl tubing and Insulated it there all the way back to the bucket Insulated the top insulated the sides like before Got a little extra insulation there because when this garage gets hot It's going to need the extra insulation to keep in the to keep the heat away and let the The pump do its work so There's the the inlet side and water's going through there through the tube comes out And from the outlet side snakes up here to the flow meter And comes right back out to the go back to the bucket There's a third plug there and you see I've got it plugged right now But that's a spot that I'm going to use for A temperature gauge and then I'll just run those wires Down through there and back up to the control panel. So I got a little display of the temperature Got my flow meter. So I know that's not really a safety thing But it would be a really nice thing if the laser had this kind of stuff to start with but I'm gonna install it
