- Hey Maker. Remember that time you forgot to adjust your LPI so defocusing didn't work and then you even got a slop error?
Haha, just kidding! That's me, throwing some laser lingo your way ;)
Let's take some time today to understand the top four things you want to keep in mind when you're engraving a project. You ready? Let's go! ;)

Hi Emily,
As a cutting board maker I will say that more oil (food safe mineral oil or cutting board/salad bowl specific oil product) is actually better for the board. Once you have applied enough oil for it to penetrate into the wood vs just a surface coat it helps keep water and bacteria from entering the wood pores and helps keep the wood from drying out which prevents cracking and splitting.
When oiling a board use enough that some stays on top of the wood. Wait a few hours or even overnight and if the oil has soaked in, give the board another coat. Make sure to do both sides and all four edges. Eventually the board will have soaked all the oil it can take and you can remove any that remains. To help protect your board further many board makers use a mixture of bees wax and mineral oil, often referred to as "board butter" for the final silky smooth finish.
As with any cutting board, the board should never be put in the dish washer or allowed to soak in water. And every month or two a new coat of oil and board butter should be reapplied.
Thanks for your great videos and for sharing your knowledge...hopefully my sharing a little of my knowledge on cutting boards will be helpful to you and your other viewers.
There's NO SUCH thing as "food safe" mineral oil. ALL mineral oil is the same, really. You should use Cutting Board oil then finish with cutting board wax. Also, if you "mask" the board first (blue painters tape) where you're going to engrave. ALSO, "air assist" is important as it helps prevent FIRES from starting.
What's your opinion on using raw pure clean linseed oil instead for cutting boards? If in a hurry maybe put it in the oven at like 220F or so to dry it. This is what I do with my cast iron if I think I would use it again soon. I love the coating I get on cast iron and it might be good for a cutting board.
(For anyone who doesn't know, linseed is also called flaxseed and some consider it a super food.)
Just getting started engraving and learned a couple of things on the video. The LPI and X & Y slop you are the only one that I have heard that from. Thanks.
you are so welcome!
Greetings from the Czech Republic. I just ❤️love❤️ watching your videos. Thanks for lots of useful hints and tips.
Thank you! More coming your way soon. 😊
I live in The Netherlands and just love your channel♥️
aww thank you!
Finally stumbled across you. I’ve heard Rick and others talk about you
Good presentation
1) Line interval: I think your scanning offset adjustments might be way off (going by the plastic comparison pic). Can you let me know what you're are set at currently? (found in device settings)
2) if you find you are wildly out of focus and already boned the board right from the start...just let it continue on...yeah, its ruined, but heck, it might be a great outcome wildly out of focus and semi-salvage the job...worst case scenario, you will have an even screw up :)
3) spot on with the less is more for engraving (but make sure to have at least some air coming out of course).
4) Mask it with tape for easier cleanup
Your videos are fantastic. honestly, you need to be training people some advanced stuff as a side gig. Also, great wood. hard to find decent wood around town.
Cloudray sells a value that lets you decide exactly how much air you want to allow when you are engraving ( even if the air is turn off in the software) and you would normally turn off the air thru lightburn when engraving but still need a little air to keep the lens from getting fouled, also a lot of people just cut the air hose next to the laser lens and add a cheap $ 2 air value there to control the air going to the head. When I Engrave at around 500 lines per inch, I don't defocus my lens and I do not have the small lines you do. (also If I am just engraving and not cutting I use a dual lens engraving head ) a lot of times I will just windex a piece to make the lasered text more uniform and then I will sand that afterwards to keep the letters dark and still get rid of the smoke ring around the text. That just goes to show you how there are many different approaches to get a good result when lasering. Please understand that I am just sharing how I do it and I am not trying to say anything negative. I enjoyed your video a lot. thank you.
Hey Dwight. Thank you for the great tips! I try to keep content like this as simple as possible since most of my audience is either just getting started, or operate hobby machines. This is great insight and I hope my viewers read through your tips. Thank you so much for sharing and I hope to see you are kind here more often. Happy New Year!
I appreciate your enthusiasm and tips. You mentioned "sealing" your cutting boards- what do you seal them with- you have to be careful if they are actually used for cutting. The oil should be enough and you can soak them in oil, wipe off the excess, and let it soak in to prevent cracking and warping later.
what font are you using? I have a million fonts but love the one you seem to like for some of my projects. right now I use a CNC router to v-carve or straight carve stacked letters so no gluing unless I want to change wood types. I have a 60watt laser coming to add more capability.
.
Hey Cliff. In the video I show that I use either cutting board mineral oil or butcher block. Unfortunately I can’t remember off the top of my head what font I used and I’m on vacation so I can’t look it up. If you remember in a week, message me again and I’ll double check. :)
best channel out there!!! Thank you so much! Do you / can you mask your boards before engraving or not necessary?
Wow. Thank you! You sure can but it’s not necessary in most cases. :)
Great tips! Yes, needs time to get up to speed......and to slow down....and not crash😂 This is the one downside of my large 1300x900 machine, but worth the slower engraving speed to be able to fit 4x8’ stock😎
In Lightburn you can automatically apply defocus ( z axis) to any layer/color. I’m slowly building my cut library, so I don’t have to remember everything😎
haha that's awesome! I didn't know that about defocus in LB! I'll have to learn how to use it and make another video. Thank you!
@@ThatMomWithALaser Now we are getting into advanced stuff (bout time :P )
To enable that, you must first go into your device settings and switch on Enable Z Axis. now you can go to your layers and adjust an offset. Really handy to defocus engraves, then refocus for cuts. I haven't used it too much (you have a lot more hours on your machine than I do. heh) but others say it works good, just remember you set it (defaults to last settings used per colored layer)
Gonna put a warning here
its buggy. use with caution because it likes giving extend space errors. might be a LB mixed with ruida, not sure. testing to see what the issue is
does lines fine, but fills gives issues
make sure to also click relative z moves only also. seems to mess up less. still errors out on cuts
Hi, Ms. Mom! Thank you so much for sharing your time and knowledge! We have been following you and you have given us the encouragement to purchase! We used your link, and we are excepting delivery sometime in late March, early April. Your tutorials are so helpful and inspiring! May you continue to spread your joy and blessing the crafting community with your wonderful, infectious uplifting spirit! Thank you, SaBrina and Walter.
Your videos are excellent . !!!! i have watched alot on most are on setting up etc but you get to the heart of it.. You are clear and easy to see what you are doing on your computer.. excellent
Thank you! I'm so happy to hear you are enjoying my channel. More to come soon! :)
Thank you so so so much. The way that you explained everything was chef's kiss good. ❤️❤️❤️
Haha I’m so glad to hear it. My pleasure!
Thank you so much! Your videos are so useful and your smile is contagious!
Aww thank you for that. It’s my pleasure!
AWESOME video! You answered so many questions for me and you're an excellent teacher! Thank you.
I love to learn on your channel. Thank you!
Any time :)
I ask this, not to be critical, but to get a better understanding. Why would the cutting side of a board be engraved? Wouldn't that make it non-utilitarian? Or is this strictly for decorative purposes, if there are people who decorate their kitchen with a cutting board? I just ordered my first cutting board blanks, and I would have thought to engrave the backside, so it could be decorative, yet still used as a cutting board. Help, anyone?
I’ve had my laser awhile now and I use it mainly for cutting foam. I’m venturing into engraving wood now and had a basic question.
If you follow tips for a darker engrave then clean it, you lose the darkness you’re trying to achieve. How can you keep the darkness and still make it food safe?
A new subscriber tonight. Hello from Australia
Yay! Hello from Florida! :)
Super instructive and easy to follow. Thanks!
I love that script font you are using. what is the name of it?
Hey question. I don’t want to carve on to the wood. Only mark over the surface with black finish. What power and speed you use. My laser is 155w
Also what’s the tool used to measure the defocus
Some good helpful tips. Just wondering why do you manually defocus instead of using the z offset setting in lightburn?
Just habit I guess.
Hi, I wanted to know what engraving machine do you have, I would love to start doing this as a side business. Thank you
So informative... and fun to watch. TY !
You are a star sharing so much! Thank you!
Can you advise which font you are using for Gallagher?!?
I love all of your videos so MUCH! Thank you.
Yay! This makes my heart happy. Thank you for taking the time to share.
When you mention defocus and go on to say you “lower it a little bit” how much more or less would you say you lowered it for a nice engrave finish? Thanks for the video...love learning with you ❤️
I LOVE learning with you too! Just lower the bed 1-2mm. Not much but just enough to blur the lines :)
Do you have a file for the "thingy" you were using to measure when de-focusing? Or can you tell me what to search for...pretty sure it's not called a defocusing thingy!!
Did you pre-treat the cutting boards before engraving, so it would engrave darker? If so, with what? I don't guess it's safe to use borax on a food prep surface.
Hi Ms Emily! How would one de-focus on a Glowforge? Perhaps set the depth manually? I’ve had mine since August and there still so much to learn! 💕
Unfortunately I'm not sure. I think there may be an automatic function? Definitely ask in the GF groups. They will know for sure :)
great job. I learned a couple of things. One question. I take it you are doing this as a job and all...Why are you not putting affiliate links in your comments? It doesn't cost your views anything extra and puts a few more nickels in your pocket.
Great tips! thanks
Invest in a thickness planer and you can take off that top layer. Then you will have a clean board and can start again like new.
Very nice explanation
Yay! Thank you.
What kind of engraver do you have? I noticed you didn't use a masking transfer tape. I have a glowforge everything I have seen uses some type of masking so I assume I don't have to mask everything based on your video and beautiful projects you make. Thanks
Thank you! I don't mask cutting boards because I rinse them after the job is done. So you're correct, you don't need to mask everything. :) I have an Aeon Mira 7 60watt. It's a more industrial type laser. There is both a link to their site as well at a video above in the description box on why I like it.
Hi, what font are you using here?
An excellent video...very informative. Thanks for sharing
My pleasure. Thanks for watching. 😃
That engraving on the center of the cutting board are really deep. Are you going to fill it in with epoxy or something like that?
I am sure you have heard how coating your wood with a thin solution of water and borax (and letting it dry) makes for a much darker engrave at lower power. Have you used that?
Thank you so much.
Great video. Keep it up where do you get your cutting borads at?
Thank you! The ones I used in this video were just from places like IKEA and Homegoods. However, www.webstaurant.com is a popular place to source cutting boards.
Very helpful!!
I like your tips. I'm wondering when you are engraving your cutting boards are you using vectors or rasters?
Mostly vectors
Hi Emily, I'm trying to engrave a person's name on wood using LaserGRBL. I set up the name using Open Office and saved it on my desktop. When trying to bring the file in Laser GRBL the file does not show up when opening desktop. Any suggestions?
Hi was wondering what masking tape you would recommend for food? Do you always tape down before you laser?
I get my masking tape from www.createwith614.com if you use the code TMWALYT you’ll get 20% off. I don’t always use the masking tape. Just depends on the project.
great tips thanks for sharing
Wow such a great channel! Amazing job! Do you know the font on your cutting board?
Fun Video Thank You
How do you know what setting to do put the laser for engraving ?
Good tips! Thanks.
My pleasure!
Great videos I enjoy watching them. Where are you located?
Thank you! I’m in Florida.
@@ThatMomWithALaser I was hoping you were in Houston, 😂, I have a laser machine but my software is not very good. I probably need a better and updated software. I just need a few classes.
Do you give personal one to one classes?
Do you have tutorial for how to use the machine?
Did you notice that your font changed shape some on Gallagher when you changed the focus?
Not at all. Did you?
It looks like it on your video. Maybe it’s just the angle of the camers
Where can I get the guage you used to measure depth?
Does your machine use water and a water cooler? Thanks!
Hey Lacey. Yes. My machine has a chiller built into it.
Great video! Thanks for these great tips... I'm currently using a diode laser. I'm kind of looking forward to upsetting my wife when I start Dad with a bigger/better Laser...(TM) LOL
Hi. Thanks for the video and the great tips. what air compressor are you using and if you recomend it? Thanks.
I have a small 8 gallon. It gets the job done but if you can get a larger one then make the stretch. The smaller takes longer to fill. I have a video on it here: th-cam.com/video/_i3NXj3_u-k/w-d-xo.html
what sort of machine do you use? (i.e. brand? model?)
How do get a design in the spot you want without a camera
Love your videos but adjust your volumes to be the same between your voice and music
Yes, I LOVE her videos and her personality but I find myself missing a lot of informative information when I’m trying to listen and mulititask because when the music plays it’s blaring but when she talks I can barely hear her so I turn it down when the music comes on and miss a lot of what she said bc the volume is so low. I find myself going back and forth with switching the volume. I end up turning it off bc I don’t have time to keep doing it while multitasking. BUT when I have time I will sit and binge watch all her videos. She makes my day.
Hi, i have been following since i started my laser journey. You have been my inspiration for my purchase of Mira 7. I have been looking to join your FB group. Can i get the link to join there please?
Great! How do you get those letters?
Okay, I have two questions :) 1. can this router out those groves that are made in your boards. (made to catch liquid) 2. By engraving you wouldn't use any tape to help remove some of the charing? Never done this, just learning.
yep, I engrave through masking tape the problem is making sure that you remove all the tape on intricate designs. you can use gaffer tape to help peal some away but have to be careful not to miss any bits. you can also use methylated spirits to help clean stubborn marks off( it seems to dissolve the residue well) or scrape it back with a cabinet scraper or sharp blade. I have played with dark wax polish on something's and that reduces the visibility of some burns. ps don't forget to add power to engrave through the tape I think it's about 10% on my 80W.
Hi I'm interested in doing this, could you do a tutorial on how to create these files using Adobe Indesign?? Thank you.
Hi
Love your channel
Do you always clean your wood after? What if it is just engraving on plywood? I’ve just finished engraving milestone cards and I actually prefer the darkness of it before cleaning. Lol still learning. Also would you recommend sealing it?
Depends on the item. If it's masked then you probably don't need to clean the board but if you don't mask it then you need to wipe off the residue around the edges of the engraving. Also, depends on what your working with for sealing but I tend to seal everything lol
Hello! What is the gauge you are using when you Defocus? And do you know what setting it should be at?
Hey there! It's called a focus gauge. Aeon Laser USA provides them for us when we get our machines. Settings will vary depending on the material and tube wattage.
Hi where do you get the laser from?
Hi Amanda. I got my laser from Aeon Laser USA. This is my affiliate link if you'd like to learn more aeonlaser.us/?ref=momlaser
I'm looking to get a laser soon, and have found your videos very informative, thanks for posting them.
Is your Mira 7 the 40 watt or did you upgrade to the 60 watt model?
Hey Josh. I’m happy to hear you’re enjoying the content. I upgraded and got the 60watt tube. The only other add-ons I got were the rotary and stand. However, the rotary along with a few other things are included now for free as part of the pre-order specials. My affiliate link is above in the description box if you’d like to request more information. Feel free to message me on IG or FB if I can help answer any questions.
@@ThatMomWithALaser Awesome, thank you. I was planning on getting rotary with whatever laser I settle one, and the stand if I get the Mira, thanks for that extra info!
@@josh_the_happy anytime! The rotary includes is just the basic one like the one I have in my videos but it gets the job done. 💪🏼
You should play with a product called laser dark and make those letters pop and then oil it with cutting board oil.
oooo never heard of that, must google it ta
Can you give me file for the tool fouces ?
When you seal these with the oil, can it be used on the engraved surface with food?
Do a bit of research for what can and can't be considered food safe. Mineral oil is fine along with some other types of oil. Check this list out www.cuttingboard.com/blog/what-type-of-oils-are-safe-to-use-on-your-cutting-board/
@@robxsiq7744 I guess my question was really I thought once engraved that surface is not food safe due to bacteria that can get into the engraved crevices and will using the oil help with that and is it now food safe.
@@alancynvideo The idea is that the oil and other stuff from, that material seals it. "Using food-grade mineral oil on wooden kitchen utensils and cutting boards provides a protective layer that prevents water from seeping into the wood and warping it. It can also prevent bacteria from building up."
So yeah..but you might do well to occasionally touch it up with a fresh coat now and then, even without engraving (after all, you end up cutting on cutting boards which digs in). Also, dont engrave too deep on cutting boards just as a rule of thumb
Do you have a link to make that focus gauge?
I’m afraid I don’t. Aeon provides them when we get our machines.
There's NO SUCH thing as "food safe" mineral oil. ALL mineral oil is the same, really. You should use Cutting Board oil then finish with cutting board wax. Also, if you "mask" the board first (blue painters tape) where you're going to engrave, you won't get those edge burn marks. ALSO, "air assist" is important as it helps prevent FIRES from starting.
Mineral oil has been used as a laxative for ages. There's plenty of safety data on it.
Food safe is about the impurities. If there is some hexane mixed in then it isn't food safe. But it is still fine for industrial lubricant and in making several types of plastic. Depending on what the plastic is intended for.
Anyway, don't eat industrial mineral oil, baby oil is probably not good due to the scent ingredient. Food safe and medical grade is pure enough to be fine but too much does cause a BM 😮😂
P.S. many cutting board oils and conditioners are made from paraffin or bees wax cut with mineral oil.
Bamboo is a grass not a wood. This is the reason it doesn’t laser good…
Your voice is piercing
What can I say? That’s my voice and I’m not a professional video editor.
Hi, nice video. I enjoyed it, and don't take this personally because everyone does it. Quit with the music. I'd rather just listen to the machine buzzing. Anything. And then I have to turn it down. And then guess when you are talking again. Please. Tell the others. Otherwise, great video, thanks again.
