0:00 - Oh, man. I am excited 'cause right now we get to have the largest unboxing
0:05 on ShortCircuit. Well, not this one right here. We have (groaning)
0:09 this whole thing right here to unbox here today.
0:13 It's a laser cutter, you already know that from the title. I wanna start with the little one,
0:17 'cause I know that this one's a laser cutter, the other one's a filter,
0:21 but I have legitimately no clue what's in this box right here. So this right here, you would put your work on top of this
0:27 laser shoots down and then curves out your stuff. Everything's kind of in this direction.
0:31 So the amount of area here that the laser is actually hitting is pretty small,
0:36 which is great because if this was just like a flat piece of metal, it would heat up a whole bunch.
0:40 Cool, we've also got... We've got a dryer vent here that's probably for ventilation.
0:44 So there's two big problems with our current laser cutter. It's not very repeatable.
0:49 So like if you want to cut a circle and then you go and cut that same circle again,
0:53 it's not gonna line up quite perfectly. It's just not very good
0:56 and also like not repeatable and not reliable.
0:59 This right here is the optional filter. So you don't necessarily have to get this
1:04 and our plan for the old laser cutter was to put it into a fume hood that strikes all the fumes,
1:09 shoots them up out of the ceiling throwing some filters and crap. But this is way cheaper.
1:13 It's like a thousand bucks and you can put it literally anywhere. So we don't have to worry about,
1:16 where we put it and put the fume hood in is a permanent thing.
1:22 We're definitely putting it to new for now. So the fun thing about this is that you don't need to bother venting it
1:27 like out a window or anything. You just place it wherever and you are good to go.
1:32 So we went for the Pro model because it's the biggest
1:36 and it's the fastest and it's the most powerful. So this right here has 45 Watts of lasering power.
1:42 That's only marginally more than what we have right now. Our current one is 40 Watts.
1:47 And the difference you're going to feel between those two
1:50 is basically nothing, but this should be because like I trust it.
1:54 We should be able to push it way faster than our current one.
1:58 It's very well packed. Just come in and look at this. This thing is not going anywhere.
2:02 Another huge advantage of this laser over our last one
2:05 is that this is a pre-built kit.
2:08 You basically just unbox it and we should have relatively little setup
2:13 before able to actually get cutting things. Whereas the last one, I think it took a week and a half.
2:18 It's interesting that they have the laser just sitting out like this,
2:24 like in ours, it's in a rear compartment,
2:27 which I guess that is kind of how they allow for the pass through.
2:31 So on this one right here, your cut size is 19 and a half inches
2:35 kind of like this way by infinity, they say.
2:39 So there's a pass through here and on the back, so you can just feed material through it
2:43 and then as long as it's not too wide, you can just, (groaning)
2:47 So this is what actually is going to focus the laser, I imagine.
2:51 So the laser shoots out this way, providing 40 watts power into the mirror back there,
2:57 it'll bounce and come around and then come out of this little lens right here.
3:03 That goes in there and this just magnets on, is that how it works?
3:06 So I just went to setup.glowforge.com, and the first thing that it's making me do
3:11 is create a Glowforge account. So that kind of brings up one of the big problems with this,
3:16 which is that, it's always connected to the internet
3:19 and that's how you get files to and from it. This was something that was a really big problem at first
3:25 because if the company goes under a year, basically left with a big old paper paperweight,
3:29 it is a bit better now because they have...
3:32 I think it's called Open Forge. It was like a GitHub thing, all the source codes there.
3:36 You can take it and run it on other software,
3:40 but not super easily. Like, I would really like it if we could have the web app
3:45 for people that sort of know what they're doing,
3:48 but don't entirely know. Then, like if we could just run like LightBurn on it
3:53 or something for like me and Colin, where we actually know what this thing is capable of
3:57 and like really get into the nitty gritty with it. Be really careful when you're moving steppers.
4:03 Just because if you move them too fast, they will put current through everything,
4:08 which is not great for your electronics. Oh, it just sits down in there.
4:11 Kinda arrives in a spot where it feels good.
4:14 It's the clamping on with this thing that you kinda use your hands to pull apart,
4:20 which is just not as good as if they had used the ones where it's like a screw,
4:24 'cause then you can like get it in place and then tighten it much easier.
4:27 If I was them, I definitely would've saved the money by using these ones.
4:31 I think this one's like $4,500, so it's not a cheap option for sure.
4:36 Hey, it's water cooled. Look at that.
4:40 You can see the water pumping right through here. I'm guessing that it has some sort of anti-microbial stuff
4:44 in there, so it doesn't get on nasty pants. So one of the things that you want in a laser cutter
4:48 is for air to be blasted kind of right at your target
4:52 just as like fire suppression. So instead of,
4:56 like the wood that you're cutting out, catching on fire, it just blows it out basically.
5:00 Connect to electrical power. Did it? Yeah. So that's being always connected to the internet
5:04 is both good and bad like for one it's always connected to the internet.
5:08 Do you really want that? But on the other hand, like you're able to print from. Damn it! It's not print.
5:13 You're able to cut it, stuff from your phone or like from like a tablet
5:18 or from the other side of the office. So you don't need to be like right there, which is nice,
5:21 but at the same time, I don't know, I'm not running a laser cutter without being decided
5:25 'cause things can catch on fire. (mumbling)
5:28 So I need a bit of material to cut here. I think this will do just fine, right around 0.4 of an inch.
5:33 So we've got that in there. So if I close this,
5:37 is it going to show me what that's at? Oh, there we go. It did it. Good job.
5:42 It has a camera and now I can just take the thing that I want to cut.
5:47 Toss it on there. Actually, that's really the (murmuring). We're not gonna cut, we're gonna engrave it.
5:51 So we're gonna put it right there. Enter settings.
5:55 Well, let's say the power is 21, sure.
5:59 Speed, 500. Let's see how fast it goes. So I have heard this camera's quite accurate in the middle,
6:04 but as you get over to the sides, it can be like a quarter of an inch out,
6:08 which is not ideal, although apparently you can calibrate it
6:12 and get it down to like within a sixteenth, across the whole bed.
6:16 Either way, it's way better than what we were doing before, which was basically just eyeballing it
6:21 and doing like the print area and just kind of hoping that it sort of landed where you wanted it.
6:25 Quite a big pane for like K side panels where you got one shot and then just done.
6:30 Precision power. Auto-focus height in inches, 0.4.
6:35 Number of passes, we'll do one... 21, sounds fine, actually let's drop that a tiny bit.
6:41 16, let's say. Speed, 500. Can we go faster?
6:45 What happens if I type in 1000? No, it won't let me do that.
6:48 500.4. Enter. Back.
6:53 Use uncertified material. Good God. All right, 0.4, submit.
6:58 So that should be right there, ready. Print.
7:01 So it does sound like there is some air pushing down. This thing is not quiet.
7:05 (cutter roaring) We want to up the laser power a tiny bit for the next go.
7:11 That is not enough. I have to say it's not super duper fast
7:14 compared to something like, I don't know a Trotec, those things are way faster,
7:19 but I don't know, that's way faster than our old ones. That was clearly not fast enough.
7:22 Oh, that was at a power of one.
7:26 Let's say power of 32.
7:30 So this also is a good way to check the repeatability. So we have these tiny little lines in there
7:34 you probably can't even see on camera and if we hit print and it lands right on those lines again,
7:39 then we're in pretty good shape. So one thing that is cool about this
7:42 is that it can laser etch on things that aren't completely flat.
7:46 It does seem like it's taking half a while, but on the other one, you'd have to manually go in and set up the focus distance.
7:51 So this is saving us heaps of time. So I don't like how it's kind of pausing there.
7:56 Like you see how it's doing the different segments and then stopping for a second.
8:00 That can mean that like, you can get a bit of fire if it stops.
8:04 I can't tell if it's modulating the laser while it's doing that.
8:09 That was pretty good though and looking, yeah, I can't see the other lines at all.
8:13 So I'm guessing that it hit them pretty much dead on.
8:17 It's been just under an hour and we've done our first little laser engrave here.
8:21 That's awesome. Compared to the last one, I took like a week and a half.
8:26 Get subscribed, click the affiliate link I guess, if you want to buy one of these
8:30 and I don't know, I'll see you later. I'm excited to use this thing.
