Find the correct DPI value for your laser

[@Ahmed-rz1qe]

This was the fastest video I ever saw explaining correctly choosing DPI for laser cut 👍🏻

[@philipershler420]

Not all of us can afford a CO2 laser. I would be very useful if you posted projects with diode lasers.

[@ImagR-Laser]

I already bought one. Will arrive soon and then I will start. Btw all of these videos can be used as well for diodes :)

I like the idea of using a real picture to do the fine tuning since in the end, picture quality is really what matters. Nice job.

[@kone023]

Power and speed are very depending for different laser power. In my Ortur, i set power 75% and speed 5000. I am not satisfied with the deepness of engraving but, DPI test is good. It would be much better with lower speed but that would increase work time several times, and, i dont have a time.

Awesome video Luki, thank you! Thanks for making it!

[@kustomkarve]

I love watching ur videos - I sure wish there were a set that used LaserGrbl or had LaserGrbl included with outcomes with Light burn - I watch many videos and the last few steps are....add to Light burn and. Love the videos though!!

[@cw4608]

This was an extremely helpful video, thanks so much!

[@subhamandal7393]

Very helpful. I want to know how to calculate correct step size?

[@bstanga]

Why not test higher DPI to insure 318 is in fact the best?

[@ersanaskn8659]

I think 282 dpi was better. Great video and ideas, thanks.

[@sigh_of_the_times]

It would be more useful if you did this with a diode laser. But it's useful for some I guess.

[@vladguran8916]

Amazing job, may i ask what kind of wood you are using?

[@keithhupp5995]

Can you explain line interval. I saw on the lightburn forum that someone put theirs in Inches instead of MM. I'm wondering if I use a lens from American Photonics for the glass tube C02 laser. I should be able to get more DPI because the beam is smaller. If I keep the line interval the same is that correct or should it be adjusted?

[@lukysek87]

hi.... it is still possible to download test files and patterns somewhere

[@mza1979m]

Are these instructions exclusive to this particular laser? How do we find the optimal DPI on a Glowforge Pro for example? We can't really set the head/bed height. This is automated. But I would like to know what DPI to enter into my images in Imag-R online when converting images.

[@williamfoster7920]

OK.... Now what was the Image mode you used? Stiki, jarvis, grayscale?..... What? Thank's for the great vid.

[@dawnbreaker84]

Great Video. Thx for your time and work :)

[@wattsartworks]

For Some strange reason, I cannot get the rulers to cut. The file loads fine in Lightburn but does nothing when I send it to the machine. Using a Thunder 51 w/100W.

[@armandorodriguezbarcenasjr499]

hi, do you do any settings with the xToolF1, I keep trying but without much success on Slate....

[@Coolmaaaaaan]

What speed and power can I use for 80w input/10w output diode laser for dpi test using lightburn

[@mcmorris06]

what way was the images processed? What type of processing so you can match it with your own photos

[@ImagR-Laser]

I used imag-r.com - kasia algorithm

[@MeIts-j4s]

Great video. I downloaded and loaded the Lightburn DPI text pattern. Each of the images in the test pattern have the same settings however. Is this correct? I am new and still learning the ins and outs of ImagR and Lightburn.

[@DwightStebner]

LOL, Luki, Thank you, You sound like a nice young lady.🤣

[@derekjenkinson8014]

Can the LB test file be sized to fit my pieces of wood, or do they have to be kept the same size?

[@ImagR-Laser]

Since they‘re already dithered you shouldn‘t change the size

[@dawnbreaker84]

How many watts the Laser have that you used for the Video ?

[@ImagR-Laser]

80w

[@brettmaxwell1360]

Great video, but unfortunately I don't have a c02 laser, I have a sculpfun 10watt diode laser, do have any videos that will suit a diode laser?

[@DougKing4416]

i did...the focus is set at the factory and once I tried this I found the focus to be right on!

hi i downloaded the files but when i bring them into lightburn it is all one layer no different layers any help would be great

Can i use the same method for a fiber laser?

Dpi means dots per inch

where are these files? i cant find them

[@charlesburleson1972]

got it, sorry

[@matthewgilchrist1068]

The light burn template file only has one cut loaded, is that because each picture has its own preset DPI so do I just have to turn on threshold or create individual DPIs?

[@ImagR-Laser]

Yes
