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

[@kevinjones6924]

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

[@cw4608]

This was an extremely helpful video, thanks so much!

[@JNWoodworks]

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.

[@dawnbreaker84]

Great Video. Thx for your time and work :)

[@AleksandarVugdelija]

Thank you!!!

[@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!!

[@MrTobbo]

liked and subbed!

[@subhamandal7393]

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

[@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 :)

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

[@user-sr2mu6xt8y]

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.

[@ersanaskn8659]

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

[@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.

[@dre5973]

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

[@williamfoster7920]

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

[@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.

[@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.

[@mariettetedem2713]

Can i use the same method for a fiber laser?

Hello.Do you have any test files for acrylic

[@armandorodriguezbarcenasjr499]

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

[@warriors475]

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

[@PersonalizariPloiesti]

Hello. the file for rdworks its not working. "File format error! Please check file version." I`m using v8. Any help?

[@wsparry1066]

can not open the test file help needed please

[@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

[@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

[@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, the test files for lightburn do not show anything when imported into lightburn.

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

[@ImagR-Laser]

80w

[@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.

[@GlenSuperDocMiller]

is the lightburn file supposed to be pass through?

Yes

Is the DPI different than lines per cm?

[@ImagR-Laser]

Dpi means dots per inch

[@cryptogimp1493]

yes doesn't open in light burn

[@ImagR-Laser]

If you have downloaded it within the last 2 hours it does. We tested it. It also opened before, but was empty

[@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

@@ImagR-Laser thank you. Final question, do you have a suggested speed/power to start at for 100W when running this test on slate?
