@shellymcdonald9967 LPI is Lines Per Inch, and deals more with the "slices" that make up an engraving. DOTS Per Inch is for jpegs, as it deals with pixels that will change on the same slice.

@@nerdysir144 can you do a video on DPI and how to change them. I find your video very good and easy to understand. I'm just learning and I have an 80 watt omtech and I use of lightburn

This was just a JPEG, just make sure it's high resolution

You are correct.

@@JohnNightraven I do have some brass coins, I could do a video on that as well.

Life is rarely so courteous to our time and patience. Gotta roll with it. 😂

@@nerdysir144 how would this technique work with a deep brass engraving or other metals? Would the bleach pass act as a clean up polishing pass?

@@mikepersin6405 I'll have to test and get back to you on that

@@nerdysir144 awesome! I have a new 100w jpt mopa and I’m learning so much every day.

I'll give it a go.

I think the 3D slice is only available on the Galvo license of Lightburn, used by Fiber Lasers. And here's hoping my tiny boi shows interest in what I do. 🤞

A su orden, mi buen señor.

Not a mopa, sadly.

Glad you enjoyed it! He enjoys causing the interruptions as well.

Y'know what, I've used that over and over, and it never worked for me until NOW when I tried ungrouping everything until I was selecting only one object. (self-dopeslap)

Nothing stopping you from creating multiple accounts, but I still value the praise. Lol, Thanks George!

Glad it helped!

Since this video it has been sorted out. I really should redo this video...

Is it being run on Lightburn or something else?

Glad you enjoyed it

I'm guessing the speeds are lower on those models. For a 5w, maybe try 50mm/sec? I always recommend testing.

Depends on the image. High resolution with even lighting will usually work like a charm, but if it's grainy or low resolution, then you'll get bad results. Ideally you'd set the dpi to the same dpi as the image.

It's there, but incredibly quiet.

The stress of learning a new skill is... well, stressful. That's one reason I try to address questions and problems as they pop up. What's bothering you about your laser?

I aim to please

Duley noted. I've since removed background music from my videos.

I'll see if I can get my hands on some

Lol, yeah that seems to be the only real takeaway from this video. I'll redo it and "card" people to the new one.

Easy explanatiom: Draw a soft line with a pencil on a white paper. It is Light gray right?. Now Draw the same line over itself, it becomes darker. Is like the same here in Laser. The Laser burns the material to make a dark line, when you increase the number of pases that the laser would do, It would over burn the material and makes it darker and darker. Sorry for my english, hope you understand me

@SarbarMultimedia I'll do a video on that in the future. And it's less to do with how dark the image is and more about how the engraving has more resolution the higher you increase it. But at some point, enough is enough, and you might as well just increase the power to get a darker engraving. But, I'll try that and do a video on it.

@@ZYairZ Basically, yeah. I believe the kerf of the laser is .4mm, so there will more overlap as you get to the 150 range.

This is a great little video that touches on a whole world of misunderstanding about laser damage to materials. . There is nothing wrong with the video it is a perfect demonstration of the tricks that our eyes play on us. Fiirst, with no power change the lines will all burn the same colour. When the line spacing is wide, your eyes can see the individual lines against the light background. As the LPI increases, depending on how far away you view the pattern, your eyes cannot focus on the individual lines. Instead, they create an AVERAGE mix of line colour and background colour to form a shade of brown. As you increase the LPI the "white" space between the lines gets less so your eye creates a darker AVERAGE shade of brown. Take a look at your lines with a magnifying glass to understand that your lines do not overburn until maybe 300 LPI. .Can I suggest you watch thi video that demonstrate.s the way that a laser beam is the master of deception . ua-cam.com/video/Na5_6okUyKg/v-deo.html This LPI principle you demonstrate is perfect explanation of what happens in one axis only for vector engraving but it also happens in two axis (DPI) as you enter the world of dithered photo engraving. You will note that Lightburn limits your options if you import a bitmap The LPI and DPI are interlinked so you camnnot make a mistake. A simple example of how your eyes are fooled is that PC monitor in front of you. Take a 10x magnifier and look at the screen to see the detail that your eyes average out. This human weakness is the whole principle behind why digtal graphics works

@@ZYairZ Hi . There is nothing wrong with your English , it is 100% understandable. If you have a laser machine , write a simple program with a single line say 50mm long.. Burn that line on a piece of wood. Move the wood and now run that line program twice in the same spot. Move again and run the program 3 times Compare the colour of the 3 tests..I think you will see that your pencil explanation is not valid for laser burns.

Thank you! Cheers!

That's what I want people to learn: How to wow.

It's very very faint, my recording volume was turned down. I'll have to redo this one.

no sound on my system either

​@@jessetutterrow4320 I goofed the sound on this, so you have to turn it all the way up.

Thank you for the 3 comments on this matter.

I mention both of the programs I use within the first 18 seconds of the video, and they are both also mentioned in the description. But yes, the music has been noted and is no longer used in my current videos.

Just in general, or anything specific to help your skill?

You are not wrong. Often times I am at the mercy of a toddler who is non-stop watching "Baby Shark", so I have to do what I can to mute it out. Also, it's been noted that the music drowns out my voice, so that'll be eliminated from future videos.

I see the wisdom in that. I think I would plan something like that if I were doing keychains or watch straps, something repeatable. But, couldn't hurt to try in this case as well.

Noted.

Noted. I try to add some kind of music to hold interest, but I'll keep it down.

@@nerdysir144 the music detracts from your video!

@@TheFalconJetDriver Duly noted 👍
