I have never watched your channel and I must say that your oration, scripting, videography, editing and choice of material for your videos ALL are spot on. I do not do laser cutting but I am quite mechanically oriented and wondered if there was an issue with build up of smoke, and or particulate matter on the laser lens? Where all the heat cracked the glass was the inspiration for this question. Great video and I love to live the vicarious life through makers like yourself that create quality content on interesting subject matter.

[@joshuadelisle]

Thank you so much, that's very kind of you. The lens is kept clear because the laser nozzle is continually purged with air, this is known as air assist and helps to blow away chard material whilst cutting. If I fire breaks out though it acts as a bellows. Cheers J

Hey. To stop the SS warping you can mount it on a copper backing plate. Works well when tig welding and i can only imagine it would work for the laser etching by sucking the heat out of the SS. Give it a go 😁

[@joshuadelisle]

Thank you, because the laser is so localised it only works with firm clamping, welding can be strong backed to account for warping but considering my table is a large heat sink I don't think copper backing will be as effective as you hope. Cheers J

I believe the Brother Scan N Cut DX series can read .DXF formatted files. They don't currently use a laser diode attachment. But it means that these types of files can be interpreted for a personal digital cutter/plotter for other types of applications. Such as cutting out the patterns in cloth, EVA foam, thin leathers, using the etching tools from Zoom for engraving soft metals such as copper and aluminum. Material thickness limit is 3 mm for cutting soft materials from paper to EVA foam. Patterns could also be used to make foiled designs, embossed designs, custom cut greeting cards, lamp shades, etc.

When I was a pup, I did my internship at Trumpf laser in Farmington Connecticut. I worked with various Co2 and ND YAG lasers for cutting welding and etching. This was back in the 90's. Its nice to see the tech that was in R&D for commercial use is making its way into homes for hobbyist at a affordable price point. When I worked for Coherent, we were working on prototype machines now commonly know as 3D SLA printers today. I had no idea what I was working on at the time would be so common today.

Can I be the one to say it: Gothic Stormtrooper armor?

[@joshuadelisle]

Actually a great idea. he'll love that. cheers J

[@andyspoo2]

The main problem you have is the focal length of the lens in use. With bigger lasers you can change the lens, which means you can have the focus point in the middle of the depth of wood rather that on it's surface. With your lens and a focus point on the top you get a cone shaped laser beam meaning you have a small focused point of the top and a large wide unfocused point at the bottom. And having a better air pump that can force more air through the nozzle also reduces burning (makes no difference with acrylic BTW).

[@en2oh]

WOW! that IS the actual output! I'm surprised that the diodes alone aren't over $1k. I'm off to find out just how many diode chips make up that beam.... One suggestion might be to use nitrogen as the flush gas - great fire suppression :)

[@joshuadelisle]

No the optical output is 33w, the electrical input is aprx 180w. The diode consists of 6x 6w optical lasers combined by mirrors, it should be 36w but there is a slight inefficiency in the coupling. Cheers J

[@FutureChaosTV]

I've been watching a lot of your videos and they're really helpful. I'm looking for a diode laser that I can use for engraving and cutting MDF/Plywood for woodworking templates. the Xtool 40W is a crazy amount of money since I'd have to buy the unit, 40w diode, and air assist. This looks like it might be more reasonable. Do you have any suggestions?

[@joshuadelisle]

Thank you so much. The xTool bundle is cheaper than buying individually but still £1650. I think the 40w is the currently the most efficient laser I've reviewed at 12.5mm per watt cutting 9mm plywood compared to 8.5mm per watt on the 30w lasers. The xTool cut 9mm ply at 500mm/min compared to ACMER which did it at 250mm/min. The xTool is £500 more but double the performance. I'm reviewing the comgrow z1 pro 20w next which is the cheapest In the 20w category. Cheers J

It has more than enough power to permanently blind you if any of that beam makes it into your eye for even a split second. If this happens, remember to take good care of the remaining eye, because if it happens again it's lights out for you. Or you know maybe build a proper enclosure for it and make sure the transparent material used for the viewing port 100% blocks that vawelength.

[@joshuadelisle]

Definitely. Cheers J

[@disignscdn]

Love your reviews Josh ! Thanks for sharing as I've never heard of this Laser Machine before. It seems very similar in layout to Ortur's OLM3. I do really like the fact that the one stepper motor is on the right hand side. I'm not a big fan of having it on the bottom though. It cuts down your engraving space of thicker objects if you don't raise the machine, but at least it's not on the left hand side making it difficult to engrave from the home position. I will be checking out their site for sure to see if they market the Laser Module though. Is the raffle open to Canadian residents? :)

[@joshuadelisle]

Hi. Thank you. Yes I've got lots more lasers from top and new companies to test against. Raffle is open to anyone anywhere but I haven't included postage from the UK so that will have to be negotiated, thanless the raffle covers the costs and my time. Cheers J

[@stewartstewartstewart]

Yeh, that’s definitely a thing now 😢

[@joshuadelisle]

I understand Mark and all I can say is I'm riding this wave whilst it's here because it's a stepping stone to great projects. The barrage of making will be coming I assure you. The truth is I posted a few making videos on blacksmithing recently but didn't get any views, but when I reveiw equipment it's exploded my channel. So I'm looking at building an audience and then showing what can be done. Minimal tool making tutorials are definitely on my list as well as low tech. I want to forge my horse sculptures again at some point, but that wasn't very profitable at the time. What specifically would you like to see?

[@teazer999999]

When cutting wood, why not make an inert gas envelope. For example, put a block of dry ice inside the plastic enclosure. The sublimated CO2 gas is heaver than air so it should make an inert layer of CO2 right where the laser is cutting the wood. The CO2 will displace the air (oxygen source) so the wood won't burn while cutting, acting as a shielding gas. Note: CO2 decomposes to CO + 0 at 2120 deg C, which can happen when cutting metal, potentially causing blowholes and splatter. In that case, you could try nitrogen or argon, both heaver than air.

[@joshuadelisle]

Good idea. Cheers J

[@totherarf]

The only niggle I have is that you would not want to be running it at 100% as you would burn the head out fairly quickly! Would a couple of passes at lower power have the same effect? Or just slower speed and a single pass? Eather way, it was a great video! I like it!

[@joshuadelisle]

thank you yes thats the beauty of a more powerful laser is you can still get great cuts at 80% and I recomend faster with more passes for a clean cut. cheers J

[@nikthefix8918]

Yes, I always run cut tests at max 60% 'cos I'm paranoid and have lost a few modules running 100%. Although they probably failed for other reasons I don't want to take risk with these more powerful and expensive assemblies. Less power, less speed, more passes works for me as long as the cut geometry doesn't require the laser to dwell too long around a certain feature and heat it up too much (only a problem if using optimized multiple passes). I've been appealing to Lightburn devs to offer a 'cut distributed mode' in vector cuts to prevent any one area getting too much attention - important for thermoplastic cutting and even applicable to engraving melt vulnerable materials. I'd rather have the laser scan over non-engraved areas in a uniform pattern just to keep any heating effect consistent. A good example here is when cutting kapton tape to make stencils. The default optimisations (in LB) will often melt at some points and fail to penetrate at others. An option for consistent burn over speed would be useful, but I appreciate that a good cut strategy would involve taking the material properties into account. However, with more optimization options, that could be left to the end user. If I get a melting problem I just run one job multiple times rather than specifying multiple passes in the cut options.

[@MrQuantumvisions]

Nice

[@joshuadelisle]

Thank you. cheers J

[@Muscleduck]

Polycarbonate would be better for outdoors use. It's more expensive than PMMA but way stronger, and it doesn't burn. A piece of PC that thick would probably stop a small bullet.

[@hyperoculus421]

Wondering what sort of life usage would you get from the diode? Appreciate it's dependant on intensity etc but any info from the supplier? tried to find warranty info and diode replacement costs etc on the site but none available... Thanks for the review.

[@joshuadelisle]

I'm not too sure because there are several factors but 10000hours is what seems to be acceptable for a diode laser. One issue is using them on 100% power continuously degrades them quickly because they overheat or have done in the past. Some manufacturers are putting more powerful fan systems to help cool more efficiently but tend to be louder. The tech is improving quite fast and even manufacturers are asking for my thoughts whilst developing the next generation of lasers, which was very nice to think that my opinion matters to them. cheers J

Hi, great video. I have a question…. I’m a shop owner and sell lots of knives. I’m looking for a laser to engrave names and the like one knives like Opinel , wooden handle knives and also on blades. What would you recommend as a machine ? Thanks in advance and keep up the great content .

[@joshuadelisle]

Thank you. For blades I would recommend a fibre laser, they're very quick likely 1000x faster. They can only do small engravings up to 120mm square but that's plenty for custom knives. I think laserpecker3 is potentially good for steel and possibly the xTool F1 but I haven't tested those yet to see. Cheers J

My version of light burn does not have those test options. I think I need an upgrade!

[@joshuadelisle]

If it doesn't I think the updates are free. Cheers J

@@joshuadelisle I think the updates are free for 12 months, after that then you need to pay for an upgrade.

Good that it comes with somekind of shielding, but I don't understand why they just don't make shielding frame of ie. 2020. Wouldn't add cost virtually at all. I mean I would gladly shell like 50-100 euros gladly for ready cut parts. Btw I'm curious about stainless etching with laser. Could you show in some future video how well it stick by rubbing it bit with like vlies 300 grit or something? Apparently that flame stop function is quite a big miss, but otherwise quite impressive thing.

[@joshuadelisle]

Thank you, I've done few stainless etchings on different machines and they're all pretty good. Even if polished out you can feel the dimple of the etching left behind. Cheers J

had to watch the video again. i entered the raffle and it took me forever to figure out the monetary value of all the choices and i missed the whole video. i more than likely still got it wrong though. and they say imperial measuring is complicated.

Thank you so much. I hope you're all sorted. Thank you for the extra view. Cheers J

The one glaring flaw is the 2mm pitch plugs.

[@joshuadelisle]

What are pitch plugs? Cheers J

[@mytuberforyou]

@@joshuadelisle they are those little white plastic plugs with the tiny pins in them- the pins are rated at only 2A and are spaced at 2mm (2mmm pitch = spacing). They are abosolutely NOTORIOUS for making intermittant contact, breaking, or burning up from arcing, because they have no positive fixation/locking or strain relief and the pin goes into a tiny bit of aluminum that makes poor contact. I would turn off out the useless fire alarm, put a pyrotechnic extinguisher like an Element or a bomb type extinguisher in the enclosure instead, and add an aviation connector on the rotary plug- and hardwire every other 2mm plug on the machine.

Can it cut very thin polycarbonate without leaving a terrible edge?

[@joshuadelisle]

This will not cut clear polycarbonate but it can do opaque. cheers J

[@philandrawis6232]

you can buy a good 60W or 80W for under $100 and upgrade the whole machine you will also have less run time and if you add jet air to the laser head you will cool the items so you don't have too much burn as you are having

[@joshuadelisle]

I think you maybe confused with electrical input and optical output. this laser is 180w input. I think the 40w optical output laser modules are £1000+. cheers J

[@eduardo33]

Do you believe that is possible to do good PCB`s with this machine?

[@joshuadelisle]

I've not tried it so I can't say for sure. Cheers J

Hi Joshua, How are you doing with the 3D Printing? Be good to see a video update about the things y are doing and what you learned? I myself have saved up and ordered a new Elegoo Neptune 3 Max FDM 3D Printer which is their biggest one so far. Bed is 420 mm square and 500 mm height of printing. They also do a Plus version of 320 mm square bed and 400 mm height of printing. the Max costs $470 and the Plus costs $350. I most likely be selling my Elegoo Saturn 2 Resin 8K 3D printer even though it is god because of getting rid of the resin filled washing water after the water washable resin is washed from the models in the Mercury XS wash and cure system I also brought is still Toxic rated and can't be put down the drain or sink, I have 14 liters stored in plastic containers that I can't set due t the sun not being that strong in good old UK, and buying a Big UV lamp be over £200 so that's not helpful. In the USA and other hotter countries they just stick the water out to evaporate away and the left over resin then sets to be thrown out as trash. But not a option in the UK sun. Someone said take it to a recycle waste center? But I have no car and taking toxic water by bus be a no no in case of spills. Someone else said do small amounts under the light f the UV curing unit I got in a glass dish. But that would take tons of time and the turntable of the curing machine is a light weight one for light hollowed out resin models not heavy water filled glass dishes. Plus if I am using the curing UV unit to do any already used water the new stuff done in the resin printer can't be done due to the curing unit being busy for tons of time. So sadly I will have to sell the resin system. The costs of the lots of paper towels and gloves and resin are very pricey anyway now. Even the IPA version to wash with be far too pricey anyway. So I stick to FDM as I can get rid of the waste and bad models easy since they are corn starch based. Also I see Elegoo now released 6 new printers. 3 resin and 3 FDM. two f the FDM printers are called Neptune 4 and 4 Pro. The 4 Pro has liner rails for the Y gantry and a two zone heating area on the bed the middle for small models and the outer with the middle for big models to save on heating all the bed when the small middle sat models are on done and the outer section not needed. the Neptune 4 link > www.elegoo.com/collections/neptune-series-fdm-printers/products/elegoo-neptune-4-fdm-3d-printer or the Neptune 4 Pro www.elegoo.com/collections/neptune-series-fdm-printers/products/elegoo-neptune-4-pro-fdm-3d-printer

Nice, I've not seen that kind of etching in s/s , gives me some ideas. BTW what is mm/pm ? The "/" already means per and pm is picometer. Try mm/min ;) Can your software spread out the engraving to prevent lingering in once place too long? Obviously, lingering in one spot doing infill at 40W is going to produce distortion. Send the storm trooper logos to Ukraine, they seem to like that short of thing. You'll make a killing ;)

Can the plasma cutter be adapted to this laser cutter?

[@joshuadelisle]

My plasma is the ortur lm 5w, I can put the original laser module back on it anytime but the controller won't support the new 30w modules. It's mainly to do with the pwm power supply. You could theoretically use one of these new 30w controllers as a plasma machine however it's not clear how the HF will affect the new controllers. I'll be building my big plasma table using a 10w laser that has an offline controller. One of the things I've looked at to minimize HF interference that a lot of people have trouble with is a ferrite ring on the controller wires. Cheers J

[@nikthefix8918]

That is a surprisingly collimated beam. More like waterjet or EDM than laser diode(s). I can usually only get that by raising the laser head and focusing long and losing power / small dot as a consequence. Perhaps the warping came from the material being pre-stressed. I wonder how consistent these 'knife-edge' beam combiners are from the perspective of manufacturing and factory setup. I worry that there are good ones and bad ones from the same supplier. Does anyone have any experience of this?

[@joshuadelisle]

It's possible, I think good quality brands will have a quality control check and a return policy just in case. Cheers J

[@NOTNOTJON]

Agree with this. I had ordered some cheap anodized aluminum to etch and couldn't do it without the material warping. Finally tried a more expensive brand of the same dimensions and same etch settings and had no warping.
