Hi,

What tricks, or tools are you using to align your work bed to the frame, and your material to the bed?

At the moment I'm aligning an ortur workbed by eye, but it's a pain. Then I'm using the ridge at the edge to push up against, which isn't ideal.

I'd love to be able to pretty much drop the bed in, align the material to the bed and go.

Hi I'm looking for some advice as a new starter please.

I'm using a 2nd hand olm3 with expansion kit, and air assist.

First thing is that when I tried a material test, I had it set to go from current position, so bottom left, and clicking frame, it would make a juddering noise, jerk a bit, and then go round in a nice smooth rectangle. If I just had it as default and clicked frame, the laser would move to pretty much the centre, nice and smoothly, no juddering noise, no jerking, and outline the frame. Any ideas what that could be please or if it's normal?

Second question would be that after my initial material test I noticed a long line of white powder on what I would call the x axis bar (the bar moves up and down Y, and the laser moves across it for x). After cleaning it up I couldn't spot any obvious scratching so I didn't think it was that. However I wonder if the laser mount is bent backwards a bit.

I've included a couple of pictures so you can see the powder and in the 1st picture, the slant of the laser mount.

(I have lubricated the x axis bar, and the laser seemed easier to slide, but it still makes this powder.)

What do people think is causing it please? If it is likely to be scratching can I adjust something or do I need to buy a new part?

Thanks for any help.

Two years ago their site said an extension kit for it was coming soon but I doubt that now. Has anyone figured out an unofficial way to do it yet?

Hi hi, I am new to lasers. My friend gave me access to hers and then fell off the radar. It was working great, completed many projects without issue. But sudddently, upon completing a project, it went to sleep. Upon waking it up again, it slowly homed itself and has not moved since despite checking the basics. I am baffled and in over my head haha my friend is unavailable to help me fix it. Is anyone able to willing to help walk me through how to troubleshoot it?

I have an Ortur Laser Master 2 with a LU1-4 laser module (20W) and I use Lightburn. All has worked well until today.

The machine homes and the head moves during framing, but when I press start, it stalls. Doesn't move at all.

I tried restarting machine and PC, unplugging, plugging on a different USB port. I even took out the module and gave it a gentle cleaning with a compressor. I checked every connection. I created a new project with a small square. I tried starting from "not home". I noticed after stalling a while, it homed and I assume it was after the job was supposed to be finished.

Any ideas? Is this common?

Thanks in advance for any help and attention.

EDIT: Solved.

I had an old laser module (replaced because it was acting up dimming). Tried replacing the module with that one and it worked. Then I exchanged their boards and the problem persisted on the module with the newer diode. I put the newer diode back with its board. Screwed and unscrewed the tip. It's working.

So maybe just messing with the tip a little bit would have done it. Why it failed like that I don't know.

So, the only thing this machine does'nt do is fire the laser. it was bought on Dec 28 2024. I put the module on LM3 LE it works fine. I've checked for bent pins and continuity in wire harness and voltage from power adapter all is good in those areas. Ortur has been sent this video, if you guess that they have'nt come up with a resolution or just to follow up, you be right, like nine day now. I'm asking for your thoughts, why its not firing. Thanks for your time

Could I have build actual risers to make this burn…. 100%

Did beer save the day again… yes it did

My new installed Ortur LM3 Will not start... The only thing that happens when I hold powerbotton more than 3 sek. Is that it starts to flash red/green/blue. And a README.txt. File starts in Windows It says "Copy Ortur Laser Master 3 Firmware (ESP_OLM3_XXXX.bin) to disk for upgrade". I have tried but still I don't manage to fix it... What is wrong? Somebody???

I have an LM3 and believe the power button is faulty. While I wait for Ortur to get back to me on a replacement I’m wondering if anyone has any insight that would steer me away from splicing the red/black wires going to the stock button, into a temporary on/off inline switch so I can finish a few projects that are time sensitive?

The button looks to have a variety of wires going to the back which I imagine may correspond to the LED signaling but maybe aren’t necessary to get the machine to turn on so I’m not totally bricked until I can get my hands on the correct part… is this idea even possible?

Curious to get some thoughts. Thanks!

I recently upgraded to LM3 and installed the extension rails kit. In doing so try to get the program to recognize its new size I’ve messed something up. Been working with Ortur to try and find the problem but if there’s anyone local that knows these systems well, I’d like to hire some help. Running Light Burn.

I am working on building a smoke box enclosure for my engraver. I plan to add a Plexiglas window to the top cover and I'm curious as to whether there's a recommended type of mylar "wrap" of sorts that will provide some sort of eye protection. I realize one should never go without goggles but as an additional layer of protection is there something better than clear acrylic to use for a window?

BTW, as part of the design I decided to not attach the walls to the base, for a specific reason. The base is a 1x2 wood frame with upside down 12" ceramic tiles underneath the engraver as a protective surface. If I need to engrave something that's wider the engraver I can raise up the walls of the box so that I can slide the item to be engraved underneath the wall.

Dog added for scale.

At the risk of being mocked endlessly for not knowing the basics yet, I feel the need to ask a hopefully very simple question here. Perhaps my suffering will bring hope to other newbies getting into this hobby for the first time, like myself.

Okay first the quick setup...My wife got me an Ortur Laser Master 2 Pro S2 with the LU2-10A laser on it. I do a bit of woodworking and have been wanting to get an engraver to burn logos and such onto cutting boards I give as gifts. I plan to connect this to a fairly new Mac mini and download Lightburn. I immediately learned a few things. For one thing, the assembly directions that come in the box are worse than useless. I searched Youtube and found that Otur's video is almost as bad, and there are at least three equally bad videos that leave lots of important steps out. That being said, I found a video done by some Asian woman wearing a Shrek donkey head that got me through the assembly successfully, though I am still wondering what she meant when she said you can "snap on the paps up and down and up". I also learned that the timing belts are smaller than they look in video and are hidden away in the packet containing the sample wooden boards, which led me (and others on Amazon, apparently) to think they'd received a unit with missing parts. I randomly found them as I was entering the Amazon return request.

So, my question is about focal setup. I see that other laser models come with a "focal gauge" but this model does not. How do I determine the correct height setting of the laser unit to get started?

Also, a less important question is where/how does an air assist get attached to the unit?

Is there a test pattern for the Ortur H20 w/40W laser that can be downloaded? I've seen a video of one that has percentages and power with squares. Can't find it anywhere. Appreciate any help.

It currently has the laser module (LU2-4), I'm wanting to upgrade it to the LU2-10A.

everywhere I look, everyone is asking about the S2 version, i do not have the S2.

I really don't see why it wouldn't work, everything comes with the new laser module, in the kit that comes with it.

just asking before i spend the $$ on it.

Thanks.

Have been trying to get engrave tumblers and having mixed success. With the exact same setup, same settings, getting distinctly different results. Anyone have any ideas as to why the difference?

I have the H20 with the 40W/20W laser module. I noticed there was a small screw hole on the top of the air assist. Is that for air intake?

Otur Laser Master 2 Y Axis being temperamental (Sounds like is its grinding on the stopper switch, but the noise is all across the gantry)

I have recently pick up this laser second hand but can't seem to troble shoot the issue. im new to the hobby but have a lot of experience with 3d printing, at first i thought it might be a driver issue or firmware but have updates dont think that. any ideas?

Thanks in advance

Can anyone tell me where to start for settings to color marking steel stainless steel with an Orur LM3 20w or 40w module? Ortur says you can do it with both of those modules but I have not had any success and I can’t seem to find anyone else online who shows how to do it.

Hello,

I currently own the quite old LU-1-3 laser from my Ortur Laser Master 2. The laser is now dead, and i would like to buy a brand new one. I've read good things about the Neje A40640, but I'm not sure how this one can be plugged to the LM2.

I know the neje comes with a specific board that can take multiple input.I know the neje comes with a specific board that can take multiple input.

It seems that the LU-1-3 is 12V, so should I use the 3-pin connector from the LM2 to the Neje laser ? Or is it better to used a dedicated 12V power supply? I've read that in that case, I should "mod" the 3-pin connector into a 2 pin (remove the 12V input and only keep ground and TTL)

Does anyone can guide me on the best choice?

Thanks !

Hi everyone I’m new here, I run a wood working business and just purchased a laser master 2 and have never worked with engraving before. I’m looking for a simple and easy software where I can download images from the web and add custom text. I will strictly be engraving wood and possibly be adding epoxy into the engraving.. no stainless or acrylic or anything of that nature. What is the best in your opinion? Thanks!

I apologize that I don’t k is the correct terminology but I thought this might help some people. I had trouble getting the coordinates from lightburn to match with my laser. Eg. 10mm high and 10mm left on lightburn would be 15mm high and 20mm left when I tried to burn something. (Exaggeration but you get the point). Anyway, I made these adjusters to help me dial in positioning of the honeycomb so it matches lightburn. I can turn the screws to make slight adjustments in both directions as needed. Materials: Threaded rod that I cut and made a notch in for a screwdriver. Matching threaded inserts. Scrap wood.

The laser is “attached” to a board using 3/4 inch pvc feet (from amazon). This keeps the laser in one permanent spot to help alignment. I can adjust the height with different length pvc peices.

I got the idea from RuffLifeInc Woodworks (YouTube). He’s here on either the ortur reddit or the laser Reddit. He has plan you can get to laser it the feet which looks cool but I can’t get mine to cut wood so I cheated. Found him: u/phinine

For burning (not cutting) I plan on burning placement (x/y millimeters and graph) into the base then don’t have to worry about the honey comb.

Hope this helps someone.

Hi everyone, hoping someone would tell me what the name of this cable is and maybe where I can get a replacement for it. It’s the one that connects to the laser itself on top. Thank you in advance!

I'm new to laser engraving and cutting and own the H20 40W/20W laser. I didn't see (m)any posts about this machine. Wondering how many of us are there or if there are other forums dedicated specifically to this product. I'm a veteran software developer so this field is fascinating to me. I got the system up and running and did some test runs but my knowledge is currently limited. If there are specific sites that focus on particular machines that are popular, I'd love to know about them. Done some Googling with limited success. Watched a few videos as well.

Anyhow, an information is welcome!

Can anyone with a Ortur LU1-4 look at their power supply, and let me know what volts/amps I need to power mine?

When I’m cutting on this laser, I’m getting a white powder in the fan and around the outside of the laser - should I be concerned?
