I would like to see a video how to change the original lense against the g8 - heard it’s not that easy. Just waiting for the delivery of my g8...
Thank you for posting such great information. I just purchased the Ortur with the 20W laser. I was going to change to the G8 lens, but I can't find it. The links provided don't seem to have any information anymore. Any help there?
Same here. I can't find it either. We're you ever able to get one?
No. I ended up not even opening my Ortur and selling it on ebay for the same price I had bought it. I am going to get the new Pro version that's out...as soon as I get my shop and ventilation system done.
I have the LM2 with the fixed lens. Is there a G8 lens to replace the regular fixed lens? If so where can I find it?
The links to your site above appear to be compromised.
Where can I find a knob to use to replace my existing lens with a g8 lens?
Thank you.
Great videos.
Here is a 3D Printable version which I created: www.thingiverse.com/thing:4556985
At 1.28 I can see you have added a knurled knob extension to your original lens that appears to tighten with a screw. I am not interested in changing out my lens right now but I would like to make my current lens easier to adjust. Where can I find that knob extension ?
Hi Got the G8 lens you recommended but how do you fit it. It just disappeared up the body and no way to adjust... printed the adjust knob but can’t see how it fits
In this video a 3d Printed a barrel and I also released a design on thingiverse as knob here: www.thingiverse.com/thing:4556985
Awesome you tried my suggestion! Are you experimenting anything with air assist yet? I would love to se how well it cuts balsa wood without it start burning. Maby make a simple plane model with it?
Yes the G8 lens has been great! Many thanks and yes to the Air Assist I will be release a video as well as a 3d printable version next week!
Thanks BUT THE G8 link does not exist anymore. Is there an alternative source in getting it?
Hi,
I have the newer 20w laser module, the lens/barrel looks slightly different. However the issue i am having is, i am unable to remove the lens.
it just keeps twisting but does not remove. I pulled the lens and it seems it can slide up and down, but does not pull out or twist out.
Finally got dialed in with the g8...used USB microscope. but the threds are loose an vibrations is taking me out of focus. I'm going to try some teflon tape to get a tighter fit. ANy lessons learned from anyone?
Tape has worked well for me...
Can you do a video that explains what commands you use in Lightburn to focus the lens. I'm using macros that dont work correctly and have a tough time understanding which way to turn to adjust. Some detail would be awesome.... and appreciated.
Seems I get this question a lot so might be a good idea! However till then: LightBurn has a setting for this. First, in Edit -> Device Settings, click the “Enable Laser Fire Button” Then quit, and restart LightBurn. In the Move window, you’ll now find the Fire button :-)
Hi there, I have the Ortur Laser Master 2 with the 4-4.5 watt output laser. If the G8 lens has a longer focal length, why didn't raise your laser before focusing? I bought a G8 lens from a laser parts supplier and he suggested the distance from the laser body(not the lens) to your workpiece should be 4-4 1/2 inches. I have seen anywhere from 2"-3" What is the correct distance? Can you make a video showing the correct measurement from the laser to the workpiece? Does it very with different power output lasers?
cant wait to see what cool stuff you can do with this g8.
I am super impressed with this lens!
i have the 7W is there a way to upgrade the whole laser? do i need to upgrade anything else
super interesting because I have a hard time placing my g7 lens with the Ortur knob. quick question: how do you place an air assist with the knob you designed?
Its a completely different assembly best explained by watching the video so you can see first hand...
Hi I watched your video on installing the G8 Lens and saw that you install it with the notches downward into the the eyepiece but noticed that my original has the notches sticking outward. Was this one inserted in the wrong direction?
How about a single element plano convex lense added to the original....simulate to co2 laser set ups....you'll need to fab a lens tube
Hello, where to by this G8 lens because the link below don't works on my comp?
Maybe it can cut coated clear acrylic
how can you identify these lenses from each other Great video and information
Sort-a as the G8 has less glass as mine is a single element lens...
I wonder if this lens and the Ortur 20W would be a badass combination for cutting. They say that the 15W unit is actually better because for cutting because of the lens focal length. So in my mind with this lens you get the good focus and more powerful laser. = Profit? :)
Ortur states the following:
"You could get the same engraving result with a powerfull laser at less power rate. But, LU15W has a longer focus length than LU20W, if you need to cut plywood, it would be better to choose LU15W than LU20W. In engraving the same materials, LU20W is much faster and can engrave much more materials."
seeing more videos with the G7 cutting better and engraving same width lines horizontal /vertical. Any plans to test and compare ? Still waiting for mine to arrive from China.
Yes I have a G7 however I like the split between G8 and G2 better. I will likely do a video on this soon
hey! love your videos!! very informative!
any chance you can post a new link for the G8 lens since the one you mentioned is no longer available
thx

@@DIY3DTECHcom thx man!
can you tell if this lens will work as well?

Would the G8 lens be good for the Ortur Laser Master 2 with a 20 Watt laser?
Yes it offers a far deeper focal length which work better with the height of the Ortur laser design...
Just purchased the G8 lens from this link and it does not fit into the 20w Ortur Laser Master. the threaded barrel is too small of diameter. did i waste money?
appreciate any assistance.
No clue on mine it does fit, however if you one of the fixed focus then you might have an issue as I don't have one of those so not sure how that works...
I just ordered an orturo 2, 15w. Hopefully it can be upgraded
To the G8 Lens? Yes it can be...
How did your 15w go?
Very helpful! What is the preferred focal distance for the G-8, as measured from the heat sink?
about 70 to 75mm
Why can no one come to an agreement on this distance? On the Ortur group the common distance for the G8 is 50mm. Why is it 70-75 here?!
Before you had G8 lens, would you be able to focus to point or to small line? I have the 20W version original lens yet, and I'm wondering if the G8 lens will be able to correct this issue, since moving the z axis, thus modifying the focal lenght didn't improve my focus.
In general diode lasers focus to a bar and not a dot. This is rather complicated to explain but the short side is the fast rise time and the long is the slow. The G8 lens has higher efficiency and longer focus length meaning a smaller kerf though thick object like foam....
Ok so I purchased the G8 from the link in the description. I finally installed it and can’t get it to focus right. The only way I can get it to focus is if I unscrew it so much that it falls off. What am I doing wrong? Any suggestions are greatly appreciated!
First do you have pointing the correct way? There is an up and down to it, second is it has very long which at minium the object to be cut needs to be from 30mm to 100mm away unlike a G2 which needs to very close. Mine is about 50mm away...
@@DIY3DTECHcom Yes I made sure it’s screwed the right way. I’ll play a little more with the distance from the material. Thx!
@@DIY3DTECHcom which way does it get inserted? Is it up towards the laser? The notches or not? Thanks
Hi, i would like to ask if there are possible way to cut a clear acrylic using diode laser ?
Sorry no, you need a CO2 laser as keep in mind a diode laser is a visible light laser so if you can see though the material so will the laser...
If you mean "cut" as in cut through, then no, but you can engrave (sort of) an image onto the surface by using a backer board or something on the underside of the acrylic. The energy will be focused on the media under the acrylic, and the acrylic will then absorb SOME of that energy. The result will be an image burned (melted) into the surface of the acrylic. I'm not sure of the success rate, but I know people are doing it and eventually someone will outsmart the law of physics.
Great video! Thanks! Does this laser cut through thinner wood?
Yes watch for up coming video!
Thanks for the video, I was wondering will the lens also make engravings clearer?
I am going to venture to say no, however this also might be splitting hairs as this is a single lens unit which provide a deeper focal point however I do not "feel" it is as clean as G2 lens.
i Just got the master 2 today and when focusing the laser it doesnt go to a dot its more of a line is that normal?
Yes all diode laser are "bars"
The 20w has a line. The 7w and 15w are not a line but a dot
Hi, do you happen to know, if the frame for Ortur 2 is expandable, meaning if you could enlarge the frame for bigger cutting/engraving area? If so, where to get the new frame parts?
Frame yes, however not sure about the firmware...
anyone know where i can buy the older for the G8 and the orthro 2...i don't have a 3d printer so i can't make one
I meant the holder
Contact this person, they can help you: www.etsy.com/shop/JohnsRobotArmy
Thanks for the tip...just made the order
What about the G9 Lens?
My understand is a G9 is the common low efficiency 3 element lens...
At what speed and distance was this done at?
Speed varies with material and distance was about 50mm
how is it on leather?
Check my video catalog as I did a video on leather. However note I will likely update it as I used a G8 lens however now been messing with G2 and that thickness been find some positive differences...
Will this work on the 20w module?
I would think so... But i don't have one to say for sure
I tried it on the 20W with & without the 3D printed holder. Didn’t have much luck with it first go around.
is the laser focus knob that you are selling on thingiverse.com fitted to the G8?
I don't sell it, however a couple folks with my permission are trying to help out folks who don't have 3D printers and yes it is designed for a G8 as diode lens for the most have the same barrel and threads...
@@DIY3DTECHcom That's great! do you have a link to some of those folks that can 3D print it for me? I will really appreciate that
@@danielbecerra520 Where are you located? I'm going to be printing one for myself and I can print one and send it to you as long as there's no objection from the designer @diy3dtech.com
@@gregoryconnors7370 oh man! that'd be great. shoot me an email so I could send you my address. becerra3000@hotmail.com
What is the optimal focal length when using the G8?
70-75 mm
Hey! Just curious what lens would be best for creating designs on denim?
Interesting denim, however independent of the material this is the preferred lens because of "distance" from the laser to the target. The G2 is best for cutting but the object has to be very close which for the trade off isn't worth. So long story short you will be happy with this one and I will have to do denim videos!
@@DIY3DTECHcom Denim videos would be sooooooo awesome, i really look forward to those
@@DIY3DTECHcom hey! I just got my ortur today, set it up and fairly certain I focused the laser correctly for the denim, but everytime I load a png image in (a rose for example) it'll stop engraving it into the denim but only the silhouette, no details on the peddles or anything, just solid, any idea what I can do to fix this?
Ortho?
I don't like saying or-tur so I renamed it...
You sound incredibly like this old tony...
funny i was thinking the same thing after coming here from a mill mod vid
Thank you! Most folks say I sound like Peter from Family Guy, I would be linked to This Old Tony :-)
Ortur, not ortho
Thanks however I prefer Ortho as who says Ortur anyway? Sounds like a made up word :-)
@@DIY3DTECHcom Haha, literally everyone else says Ortur. You're the first I've heard making it sound different. Ortho comes from a Greek word meaning 'straight'. Orthopedics, orthodontist, etc.
@@TheFlyingKiwiNZ Isn't a laser "straight"? LOL (I couldn't resist :-)
Good. I didn't have to be the asshole this time.
I can see why you didn't show how easy it is to install the G8, because it is impossible. Wasted money.
Then your doing something wrong! I have using the G8 for quite sometime with a lot of success (as many other have too)...
it says theyre sold out? any other link for genuine g8 lenses?
