How does this guy not have more subscribers? One of the nicest You Tubers to watch and provide honest reviews of products.

[@SteveMakesEverything]

Quality over quantity 😉. But certainly tell the world that this channel is here to help ramp up Makers with a helpful community.

[@ericeinsmann5559]

Steve, as mentioned by Vintauri below, you can bump up the homing speed in lightburn. From the lightburn console, enter $$ and this will list all the g-code settings for your laser. $25 is the homing speed. Simply enter $25=2000 (or whatever number you choose) and this will update the homing speed. Forgive me if this is obvious to you, I included this info for anyone else that may happen to see this and wants to know how to do it. thanks!

[@SteveMakesEverything]

Yes for sure. My gripe is that they chose such a slow default.

[@Longer3D-mo8sj]

Wow, your review is wonderful and objective. We will try our best to do our best!

[@SteveMakesEverything]

[@eddrm4685]

Great video! I watched several other videos and noticed the start/stop on all the tests had that burnout hole and thought like you there was an issue with this laser. The engravings were bad as well on the other videos, nice work noticing and then actually fixiing the issue. I was thinking it was a accuracy problem because it affected cutting and engraving so I dropped any thought of buying one. Your video popped up and I thought ok lets see what steve has to say, thinking if he says it's awesome he might be a shill. I think you proved you are doing fair and honest reveiws here. (not a shill) I bought the Longer 10w with your link and will do the same if I decide to buy the 30w this weekend. Thank you for all the work you put into your videos.

[@SteveMakesEverything]

Well I like to be thorough. When I saw the engraving results, I seriously told Longer not to sell this laser yet. If a laser is terrible I would certainly say something. I’m just happy that Longer didn’t have serious issues and that the solution was easy (after 3 days of email exchanges with them)

[@Vintauri]

Excellent overview of this laser! I'm glad we could compare notes and that you found the root of the issue. I did edit my device settings to bump up the homing speed a bit as it was ridiculously slow. Thanks for the shout-out!

[@eddrm4685]

Heading over to your channel right now.

[@SteveMakesEverything]

Thanks Steve. You certainly helped inspire me to dig into some of the issues I was having. Community is so much better than competition 😁. We definitely need to chat more.

[@ffindustries752]

Thanks... I had some strange thought that it needed fancy settings. But someone else gave me the clue. The other image settings are dots. And shading is about the concentration.

I love Longer. I dont have any Longer Lasers but I have two LK5 Pro and an LKp4ro printer and they have been the least problematic of all my printers. Maybe Ill put this on my wish list.

I definitely agree. They make great products and in the $

[@ValleyForged]

Love the Longer as well. They don't have all the 'best stuff' but they never fail me! Also, the kerf on the 20w is smaller than the others I have tested. Love to have you see if this one is no different. I should be getting one soonish as well. Thanks for the great work!

[@SteveMakesEverything]

I think they were happy with tried-and-true technology for a long time, but with the Longer Laser B1 30w, I believe they have taken great steps to move into the spotlight on new tech. They compete very favourably with xTool and Atezr with this laser

I really should share mine, but it’s pretty simple to create. Go to Google images and look for a greyscale gradient. Drop it into Lightburn and set it to a grayscale engraving.

My B1 gets delivered tomorrow. I am new to all of this. Where in lightburn do I change that setting from g3 to reg g?

[@SteveMakesEverything]

You will see this when you are creating a new device for your your B1. By default it will be wrong, but you can change it there

[@otexugodewallstreet2581]

if i am not wrong, you can edit the homing speed in the config of machine, in the lightburn

[@deanmiller294]

Where is that setting? I know you can change the whitespace speed, but don't see a homing speed.

[@eddrm4685]

Would it bother the machine to just move the head close to stops/switches by hand?

[@eddrm4685]

move the head close to stops/switches by hand...then have it home itself, is what I'm asking.

[@SteveMakesEverything]

Yes you can tinker with some Lightburn variables to change this. My only gripe is that the default value is far to slow

[@SteveMakesEverything]

It’s an option, but you can’t crank the head over too quickly

[@billmurphyoutdoors337]

I just bought the longer b1 40 watt and it is a great laser but the way they hold the laser head on the dove tail is very hard to get to when you have big hands like I do...was wondering how you over come this problem...Bill

[@SteveMakesEverything]

Hi Bill. Yes I agree that they make the screw very hard to get too. I don't have a solution for this other than to use needle-nosed pliers or maybe 3D print some kind of extender to bring the screw out further. Or get a longer screw

[@johncrunk8038]

Does that Y limit switch actually work? On my machine, the laser head hits the frame before the limit switch is touched.

[@SteveMakesEverything]

I 3D printed a little extension to press the limit switch sooner. If you have that and it’s still hitting then maybe it needs to be longer

[@texascrossbowdude636]

Xtool uses their own free software creative space and seems easy to use for beginners. Videos I've seen show with creative space you tell it the type of material, thickness and it automatically sets the perimeters as a good starting point, does light burn have a similar feature?

[@SteveMakesEverything]

In lightburn you can use the material library. It’s kind of similar in capability but is a bit more complicated. Overall lightburn is more capable than xTool XCS but has more of a learning curve. Also newer lasers from xTool and others, have more features than traditional diode lasers and these aren’t supported in lightburn

[@MichaelAcks]

Thanks for the review Steve! How do you feel about the Longer B1 vs the Atezr L2?

[@SteveMakesEverything]

These are always tough questions, but based on cost, power and ease of assembly, I’d give the edge to the Longer Laser B1 30W

[@maccaslasher]

[@egonverleysen695]

Nice job!! THX!! but I wonder if there ever will be a laser on the market where you could choose you bed size..... just wondering!! I would be interested!!

[@dreamkiss4u]

what do you think about the creality falcon 40w laser cutter engraver thats pretty much the same price range?/

[@SteveMakesEverything]

Creality makes great products so you should be fine.

[@eddrm4685]

Well I have not purchased a 30watter yet...I plan to, but see some decent looking upgrades on some of the options out there. Any chance you will be doing a reveiw on the Atezr L2 36w Laser? It would be great to know how theses 2 compare. The Atzer is about $350 more, I think the upgrades it has might be worth it. What do you think of Atezr as a company? Going to watch your videos on Atezr products now.

[@SteveMakesEverything]

The 35W L2 is essentially the same laser as the V35 so you can compare output to that. I’m not sure what upgrades you are referring to on on the L2. The only significant one is autofocus, but it’s far too slow for me to ever use. Just some clarity of 35W lasers vs 20w or even 10w lasers. Don’t get hung up on power as the key feature. Most laser companies show 35W and 40W lasers cutting through lumber, but in reality that is never a use case you are likely to have. Instead think of power as a gauge of speed. Higher power laser can engrave and cut faster. This is more important in a business than in your house,so if you’re on a budget, then opt for a 20W laser and you won’t really be disappointed, but you’ll save a ton of money. Both of these are great lasers, but right now, I would give the edge to the B1.

[@eddrm4685]

How about the linear rails would they be worth the extra $$$ ? Are they on X and Y ? One of the reasons I am looknig for more power is to cut into some rocks from N.H. beaches... Some one had a video where they cut into a rock with the B1 30w about .5mm deep, it looked good, how true that is I don't know. My Longer 10w (I think) melts the rock and most of the time (depending on the rock) embosses what ever I am engraving. Thank you for the feedback...going to wait a bit before I buy...Hopefully the sale on the B1 doesn't end.

[@SteveMakesEverything]

@@eddrm4685 The linear rails are nice. If your 10W is melting the rock, then your speed might be a bit slow, and you might want to go faster with multiple passes. From any stone that I have engraved, I can say that results can be very unpredictable due to the composition of the material. I don't honestly think this has much to do with the power of your laser. I've taken two stones that have looked identical in color, yet one engraves nicely, and the other basically melts. I now try to do a sample of tiny engraving on the back of the stone to ensure that the main engraving will be what I want.

Please help me I have a DAJA d6 laser engraver, I want to engrave personalised initials “in gold”, is there some kind of gold foil I can use for this? ,

A diode laser can’t engrave gold. For this you would need an IR laser or fiber laser

[@bustamango863]

@@bustamango863 Ah! I don't know of a particular foil that would do this (other than gold, of course), but in this case, I think you would apply it the same way you would if you were gilding engravings in wood.

I used your affiliate link to go to their website and couldn't find anything.

Hmm is that something I said? I don’t know of a 30W upgrade for the OLM3. I’m not sure what Ortur has been up to lately. They have great lasers and used to own the market, but they gone quiet over the past year.

​@@SteveMakesEverything Are you interested in testing our K30?

[@Ingannapoltron]

Good evening, I saw your video and not knowing the English language I tried to understand something. Did I want to ask you for an opinion? this 33 watt B1 laser today 10-04-24 is offered on Bangood at a price of 657 euros which seems low compared to other lasers of similar power. In your opinion is it a good deal or given the price difference is there something that isn't convincing. I would be grateful for your response and I apologize for the translation. Luca - Verona (I)

[@SteveMakesEverything]

That price seems to be good for the 33W

[@eddrm4685]

Oh yeah.. one of the reveiws had an issue with the air assist. The issue he had was weak airflow at the cut. Did you notice any issues here? I'm guessing no or you would have mentioned it. Thx again!

[@SteveMakesEverything]

I didn’t see any issues with airflow. It is possible that the air hose was pinched by a zip tie that was pulled too tight.

[@isaiahgillett2573]

Vintauri mentioned that the airflow valve was a bit wide for him so he tried putting a tape over it and pulsing the laser to get narrower opening and he saw cleaner cuts. That was with the 20w.

[@SteveMakesEverything]

@@isaiahgillett2573 He and I talked about this, but I didn't try it. His results seemed to look better with restricted airflow, though I'm not sure why just using the valve didn't produce the same results.

[@ainttakenanyshit]

The early machines had a nozzle opening that you could "drive through". Longer listened and now the units are shipping with a SMALLER / proper sized opening. I'd throw that "air valve" in the trash as when you need air, go full blast, when you don't, turn it off in LB. Longer specifically states to NOT use the valve as it will load down the pump, burn it out and and cause WWIII 🙂

[@TheUnofficialMaker]

has anyone modified a co2 laser to run with a diode laser head?

[@SteveMakesEverything]

Are you asking about a CO2 laser that is also a diode laser? I have thought about this with my DIY CO2 laser, and in theory, it should be pretty easy to do. But I'm not sure there's a lot of value since a CO2 laser can do 90% of what a typical diode laser can, plus it can do a lot of this a diode laser can't.

[@homehobbybuilds2450]

Hi Steve. Would you recommend this laser over the xtool 20w or the atezr 20w for overall use (hobby use and small business production)?

[@SteveMakesEverything]

Well when you factor price, performance and features, I would favour the B1 30W right now.

[@ainttakenanyshit]

I WAS on the fence between the Longer B1 36 vs 48 watt machines. I had a Algolaser 22 watt which had "issues" and decided to order the B1 36 watt. From my understanding, the lower power lasers usually perform "better" in terms of quality with fine detail as their one diode, (5 watt) or two diode, (10 watt) lasers have a smaller beam, which is what you want for fine detail. For me, the B1 36 has a 0.08mm x 0.15mm beam profile and the B1 48 has a 0.10mm x 0.15mm beam profile. SO, unless you really have a need for more power, the B1 36 was/is my choice.... IF your piggy bank has extra jingle, I'd buy the B1 48 watt and add their 2 watt "ruby laser" that has a 0.03mm x 0.03 mm beam profile... The Longer website is out of stock with the Ruby and as of right now, 4-8-24 2 P.M EST, big A has the Ruby head for only 399. I was feeling a little flush and I also bought the Ruby from big A which SB delivered today - my B1 36 is also out for delivery today via UPS.... **CHRISTMAS** IN April 🙂

I try not to answer questions like this. 😁. In general I prefer the Longer over the Sculpfun, mostly because the Longer laser has been keeping up with innovations whereas Sculpfun seems to be selling the same old technology for years. Anytime I’ve had to talk to Longer they’ve been pretty responsive, but keep in mind as a KZbinr they probably pay more attention to me because they don’t want me telling viewers their support suck.

@@SteveMakesEverything wow thanks for this insight. I already have an Ortur and was naive enough to believe that 5 watt is enough for engraving business. Now I'm looking for a 20 to 30 watt machine, I dread the CO2 because it seems they are sensitive and high maintenance. Saw the new sculpfun 33 watt and Algo laser 22 watt. Do you have a review video of Algo laser alpha? Thanks for you vids very helpful. 🙏

[@SteveMakesEverything]

@@saj9814 I think I was supposed to get an Algolaser, but I haven't seen it yet. I believe they are owned by Ortur though. Definitely CO2 lasers require a bit more TLC -alignment, optic cleaner etc. They aren't an appliance like a toaster for sure, but rather an instrument.

[@sigh_of_the_times]

I feel longer really dropped the Ball, I think they new of the software problems and sold the b1 to drag in cash and 2 they disappoint me because you guys have to figure out the problem for them and now the question is did they fix the software problem and the air assist problem that showed up in other videos. I really wanted to buy the b1 but if they still have the same issues I will go with sculpfun 30 watt lazer. It will be my first lazer and the last thing I need is to have problems right out of the box.

[@SteveMakesEverything]

I love a contrarian opinion 😁. However I haven’t seen any real software problems with the Longer B1 and having used it in my own shop since I got it, it remains one of my favorite new diode lasers. The only problem I ran into was in Lightburn, which selected the wrong driver during automatic setup.

[@ainttakenanyshit]

Hi Steve.... Yup, another question from frequent flyer Hank.... BUT, THIS is really important - (I think).... Well, UPS says my B1 36 will be delivered tomorrow, Monday 4-8-24. From the assembly videos I've seen, the belt "idler/tension/adjuster pulleys" are SMOOTH and not toothed. I will know for sure tomorrow what type idler pulley Longer is NOW using, but, It just seems to me, my design engineering self, that for a toothed belt to roll over a smooth idler is not optimal, squishing the teeth vs having them run in the proper slotted teeth. I believe that a toothed idler will give the belts the PROPER seating when they run over them. I think that IF I decide to change out the smooth idlers with toothed ones, it should be done in the very early hours, if not immediately, before running the machine. What is YOUR opinion on smooth vs toothed idler pulleys?? Thank you for your experienced reply.... Hank P.S. (IF I am way overthinking this subject, You gotta tell me, I will appreciate your comments)....

[@SteveMakesEverything]

Rest assured, the presence or absence of teeth on the idler pulleys is not a cause for concern. The idler's primary function is to maintain the belt's alignment, not to necessarily engage with the belt. What I will suggest for the B1, though, is to engrave a big circle (~100mm dia) to make sure the arc is smooth. On mine, I had to lower the X and Y acceleration values in the machine settings because, with the 40W module, the weight was just a bit much for the steppers to push so quickly. I don't recall seeing this on the 36W module, but it's worth checking. I don't think there is anything mechanically wrong, but rather, the default acceleration values are just too high for the laser module's mass. When engraving a circle, the X and X are constantly changing, so with a heavy laser module, the gantry is constantly jerking around which amplifies the inertial effects.

[@ainttakenanyshit]

@@SteveMakesEverything Thank you Steve.... I really appreciate your advise.... Being retired from a career working for KSC, I have a tendency to “over engineer” common, everyday items it terms of " what does NASA require"?

@@ainttakenanyshit 😀 Well, this made me laugh, but I can relate, having spent many years in industries where if someone makes a mistake, people die.

[@ainttakenanyshit]

With the exception of lower power in the 20(24) watt model, would you say the units are basically the same in features and build quality? What is your "ideal" belt tension so as to help reduce line squiggle, BUT, not to over-stress the belt pulleys/bearings? These bearings will run all day long in a complete circular manner and when engraving very small images, the very small rotational motion of these bearings have a tendency to have more localized wear with the very small "rocking" effect in the bearing track. How tight is tight enough for belt tension? Thank you for ANOTHER great video that answers a lot of the questions "we" have about these machines....

[@SteveMakesEverything]

All B1’s use the same hardware regardless of the laser power, so the same features and quality regardless. You won’t get localized wear on the pulleys and rollers because they make several rotations when moving even short distances. However they bearings, so you might eventually have to replace the rollers, though I haven’t ever had to replace one - this applies to any laser btw. As for belt tension, they should be tight, but you should still be able to easily squeeze both sides of the belt together. They aren’t guitar strings.

Hi Steve, need a favor please. Big "A" has the Longer B1 36 watt kit with some material for ONLY 899.99. Now, I want to hit the wood burning and maybe use my current hood. IF the B1 can be raised buy ~1/2 inch, the bottom tubular frame may just fit underneath the B1's frame and the extra 1/2 inch needed for each side may just work. Can you please report the width and depth of your B1? The nearest 1/16" or so will let me know if my plan will work. Thanks ahead of time for your measurements. Hank P.S. If you may also measure the distance between the left and right feet, (not the bottom of the foot, but the foot SCREW - itself), THAT will be the determining measurement if my old hood will work with the hood's bottom frame tube will fit between. Thank you BIGELY for your time....

[@SteveMakesEverything]

Hi Hank, For the dimensions, you can look at the Longer web page. My laser is currently on loan, so I don't have it at my fingertips to provide a measurement. The laser is a light frame and you can raise it to any height you need to. Just remember that there is limited Z-travel so whatever you slide under the frame needs to be able to reach the laser.

[@ainttakenanyshit]

@@SteveMakesEverything Thanks Steve. I bit the bullet and just bought another enclosure that will have room to spare. For 99 bucks I bought the enclosure for the "Twotrees TS2 machine with dimensions of 800mm x 800mm x 400mm, (31.5" x 31.5" x 15.8").... I understand that there are two "optional "cutouts on the right side, (front and rear), and on the left front side which may be opened a bit to provide some cross air flow over the machine which "should" help with smoke "withdrawal". I'll have a couple of inches to spare and from the reportedly low airflow that the included fan provides, I bought a 4" inline duct fan - ~130 CFM vs the maybe ~60 CFM stock fan. I am going to mount a full 4 inch air duct connector to the enclosure to take advantage of the full 4 inches of available duct diameter. My first cuts will be to make a 4 inch "backer plate" for the duct adapters.... These enclosure kits often use only a 3 inch to 4 inch diameter vent adapter which restricts what airflow is possible. This coming Tuesday is MY B1 day... 🙂
