Hey everyone, looking for some advice. I’m making these layered ghosts for a painting, and using the 3M adhesive to put them together. Current setup is milky white acrylic base with a layer of 3M, transparent lavender and frosted lilac on top. You can clearly see the adhesive through the transparent lavender acrylic, or the main ‘body’ of the ghost. Pieces are small, overall size of the ghost is only about three inches. Is there any way to minimize this appearance? I’m new to this, so any help would be appreciated, thanks!

I hope everyone is having a good day like I did. I need guidance my dudes. I have 0 experience on laser engraving/cutting but I own a 3d printer. Please point me into the right direction regarding software, parts(incase i need any), learning materials (informational youtubers,etc.), tips and tricks of the sort. I have started assembling it and had to leave for work. I would really appreciate any help. Thanks in advance!

I’ve been using my SCULPFUN S70 Max for about six months without any problems. Until recently, it was cutting plywood cleanly and consistently.

The two photos show the same material test performed on opposite sides of the exact same plywood board, using the same settings and a single pass.

In the first test, the 100% power square cut cleanly through the plywood. When I repeated the test today, none of the squares cut through—not even at 100% power. Instead, the surface became increasingly scorched as the power increased.

I’ve cleaned the laser head and replaced the protective lens, but the problem remains. It seems as though the laser has lost cutting power: it produces a lot of heat and surface burning but very little cutting depth.

Has anyone experienced this? What should I check next?

Before I go down any potentially useless bunny trails, is the double line output from my laser most likely due to mirror 3 not having the beam centered down the tube and thru the lens? You can see vertical "shadowing" as well as that shadow line is offset to the right as well.

Just trying to work effectively as the laser is in my Florida garage and it's hot as Hades out there.

TIA for any help/input/suggestions.

The laser is a Monport 2028MF upgraded to 90w RECI II tube and power supply. I last used the laser about 2 months ago without any issue to cut 1/4" acrylic.

Hi all! I've been engraving shapes on iridescent acrylic, and tried using two different lasers but with the same Lightburn settings (engraving at 800mm/sec speed, 20% pwr, line interval 0.1000 mm/ 254 lines per inch).

Despite using the same settings, I'm getting very different engraving outcomes. I engraved the one seen on the left with a Nova Thunder Laser (6 mm nozzle), and the one on the right I used a OneLaser XRF (3 mm nozzle).

I prefer the density of the right engraving (OneLaser) compared to the left (Thunder Laser), which feels lighter and hazy. I've played around with power/speed settings, and line interval, but haven't gotten anywhere close. Would anyone have suggestions on what settings I could modify to get my Thunder Laser to put out a result like the OneLaser engraving on the right?

HUGE thanks in advance!

EDIT: I realized I missed some important details thanks your comments. Here's the laser power info:

OneLaser XRF: 38-watt RF metal CO2 laser tube (about the equivalent of a 60W glass tube)
Nova Thunder Laser: 60W

Engraving on Iridescent Acrylic (extruded). I use sheets from Houston Acrylic.

I have a PS48 laser from full spectrum laser. I have had nothing but problems with it. I have replaced the controller with a ruida, the tube,the tube supports, the mirror mounts, the mirrors, the lens mount, and the focal lens. I am still not able to keep it in focus. I have gotten it to cut well for about an hour maybe two of running, but then it goes out of alignment and just won't cut.

I know that there isn't much left that I haven't directly replaced and calibrated. I know the tube is putting out power and the mirrors are not over absorbing the beam. One piece that may still be defective are the bearings. I've read about this, but I haven't been able to find anything about what it should look like, or any examples of what a defective one would act like.

Does this movement look normal?

Does anyone have any other ideas?

I’m not sure if this is the right group, but I’m starting here with this attached picture. Can you tell me how these are made? I see many earrings like this but I thought laser cutters cannot cut clear acrylic. Help!

I am working on figuring out nesting as I am making large quantities of stuffed animals for my small business and need good lay plans. This has been bothering me a lot.
I use Inkscape for the patterns as I find it to be the easiest software for this kind of thing and I make sure to clean it up as much as possible before moving it to deepnest. However for a lot of these patterns, when I import the svg files into deepnest, it adds so many extra boxes and rectangles into it.

I have had this issue before and I have previously fixed it. But now it’s happening and I have no idea why.

When I first had this problem, I had gone to outline view, ungrounded everything, un-clipped everything, and deleted everything extra that shouldn’t be there. And that fixed the issue.

But now it’s doing it again. There’s nothing that appears in outline view, there are no extra nodes, no extra paths, I am stumped, I swear I have tried everything.

One thing that comes to mind as I am writing this is that I do have an ink cut extension but I am not sure if that should even change anything in my file.

I do not want to change softwares as this is the only open source nesting software that actually does what I want, is simple, and free. I have tried other ones but they all suck in comparison. I also don’t want to spend money on this kind of thing

looking to have a dxf file created for this to be laser cut from one piece of metal (Coordinates would be different). roughly 7’ x 4.5’ high. let me know if this would be possible and what you would charge for something like this.
