How to Focus a Galvo Laser

[@mysafename1694]

I tried this yesterday & I did get the nice loud frequency sound on one of those metal business cards. My machine has the manual focus with the handle at the top. And I'll work on printing out a custom measuring tool.

[@mysafename1694]

Follow the same procedure. I'm assuming if you have a 20 W / Versus a 30 W. Mine is a manual focus. I've been getting pretty good images when I just hold the button at the top and turn the manual focus until three dot seem to line up. I get it as close as I can possibly get it. It seems to work, but I will try this. I've only had mine for two weeks. So I'm still testing and figuring out what works the best. Yes, I do have a 3-D printer. My lens is 110 x 110 that means I believe that I get 4 1/2 inches approximately by 4 1/2 inches. Light burn comes up. 4.33X 4.33 this is the measurement that came up during the set up. And discovery mode.

Was für Einstellungen bei den Monport 30 W Mopa Faserlaser in LightBurn und was stellt man bei dem Q-Puls eine wird leider nicht erwähnt.

What is the black material used in the video please, the one were you engraved photos of animals

[@stephensharma3259]

I think its black acrylic,

So my settings for each one of my colors is going to be changed on my C02 side?

[@lightburnsoftware7189]

@@Golfexpertbelieveme - Not sure how this relates to focusing a galvo laser. The question is confusing.

[@Golfexpertbelieveme]

@@lightburnsoftware7189 well I was following along and noticed something so I thought I would ask a question to the lightburn people. Didnt realize you only answered questions that pertained exactly to the video.

[@alattecharm]

I followed the instructions to find focus length as well as the calibration steps for a new lens. Is there away to adjust the focus beams? When I had my 290 lens, all the beams met in the middle when focused. Now with the new lens all the beams are spread apart. Is this able to be adjusted or will I need to manually find focus with a ruler each time? Thanks!

[@ainttakenanyshit]

When you find the perfect lens focus, note that distance. Then under the galvo head there should be screws holding each of the two red pointing lasers. Loosen these screws and manually move that red laser pointer to dead center of the main - center laser beam. Repeat for the second red pointer and then ALL three dots will be centered. Gently tighten each of the two red pointers snug, not "head bolt" tight, but, secure firmly. See my suggested lens focus method above as I think it will give you a perfect focus by the "burn average" method.... Hank

Can this program be used in place of Ezcad2?

[@lightburnsoftware7189]

Yes, it is an alternative design and control software.

[@authentic4225]

@@lightburnsoftware7189 When using lightburn there is no color markings although using a mop laser?

[@northamericancannonllc]

yes, lightburn uses the ezcad driver hardware. lightburn is a more intuitive software- easier to use than ezcad2. my new cloudray fiber laser came with both programs. i preferred lightburn.

[@harinarayanan.p1063]

details of the laser used?

[@RicardoCostaBebedouroemFoco]

Please clear my doubt! Can I make 3D relief woodwork in Lightburn? Like following the contours, making the lines more realistic, I don't know if I was clear! Hug!

[@eugeneallen4373]

yes. You need to learn grayscale

[@lazerpug]

How does this process work for a CO2 galvo? is it still based on sound?

[@lightburnsoftware7189]

For CO2 it would not be based on sound. It would be visual inspection and you can run a ramp test to help with finding the correct distance for your lens.

[@LockLT]

I find ramp test easiest way for CO2

Hallo haii,why my software lihtburn go problem?got any solution. When i use word it not in straight line ,it make zigzag on word,cause my machine shakking and the word tha i cut not accurate,can u solve it for me,any setting for it make nice line?

[@lightburnsoftware7189]

If your lines have zigzags it could be a few things. It could be that you have the speeds set to high for your machine or that physically you need to adjust something on your laser. If you have pictures and some additional information send us an email [e-mail]

how make draw on lenses????

[@Golfexpertbelieveme]

its only letting me go to 20khz?

[@umargul5644]

Great ❤

[@758Redwhulf]

Why don't you guys just create a comment? Section on each profile and light burn so that people can put the notes on there about the focal height and stuff. Like that. Maybe even make it where it can show at the top of the screen at all times

[@758Redwhulf]

Sorry about all the random punctuations...i was talking to my phone and it acts crazy

[@lightburnsoftware7189]

There is an option to add project notes to any project and also a checklist when you start a job. Since each lens is its own laser profile in LightBurn your best bet would be to use the Job checklist for the focal distance. We just released a video on this: kzbin.info/www/bejne/pYOkXqeAnKaBg8U

[@michaelv.8753]

👍

[@richardknezevic7371]

You can just use the red dots on the laser keep it simple

[@lightburnsoftware7189]

Many Galvos do not have the red dots for focusing. (The galvo in the video is one that does not)

[@richardknezevic7371]

@@lightburnsoftware7189 thank you for that information, then I am lucky as my unit has two red dots on my unit. cheers for the reply

[@JustinAlexanderBell]

​@@lightburnsoftware7189 What are the two brass thingamabobs?

[@corey.morreale]

those are definitely red dots but once a lens has been changed those need to be adjusted as well and this method (creating a jig) will be much faster

[@eugeneallen4373]

Mine doesn't work in Lightburn yet. Hopefully LP will fix that.

[@758Redwhulf]

Or maybe even engrave on the frame of the lens with the laser lol

[@lightburnsoftware7189]

I like to use sticker labels. It is definitely a safer option.

[@758Redwhulf]

@@lightburnsoftware7189 lol. I agree.

[@ainttakenanyshit]

NOT MEEEEE....

[@fivefoldphoto]

Wait, do I need another laser, to engrave onto my current laser? And what if I want to engrave on the new one but it's bigger and wont fit under the old one?

[@758Redwhulf]
