- This video shows you BobsCNC CNC router engraving on glass using a diamond drag engraving bit.
how to engrave (etch) on glass and soft metals on a CNC router using drag bit engravers. It also shows you how to set up the CNC router for engraving the glass and what engraving tools you will need. Engraving n glass is very different than carving. In fact, some projects can only use this method. when you don't have an engraving machine, a CNC router works just as well.
Etching with a drag bit is much easier and less messy than wood carving. There is glass dust but it remains very close to the etch line. A quick vacuum cleans it quickly.
This method also works with brass, aluminum, and any other soft metals.
It is STRONGLY recommended to use a spring-loaded drag bit when engraving on glass with a CNC router. This eliminates possible variations in pressure that can break the glass. It also is very forgiving for a spoil board that is uneven...you can have 0.25" variation and will still get a good project without damage or glass breaking.
Glass engraving can be done on any CNC router. This job was done on a BobsCNC evolution 4 (evo4)
If you own a CNC router, please take this survey: bit.ly/3r5XzNh
CNC settings for the diamond drag bit:
→ Spindle remains off
→ the tool is setup as an endmill in the tool library
→ Feed 30 inches per minute
→ Depth of cut 0.05 to 0.1 inches
If you search Amazon for a spring-loaded drag bit, you will find one that is not Widgetworks brand. DO NOT BUY THAT ONE IF YOU WANT TO ENGRAVE ON GLASS. The ratings repeatedly say the tip breaks on glass and other hard materials.
However, it does have good ratings for acrylic. Here is the link: amzn.to/3bgWiwK

My goodness, this bit is amazing! I have been etching on glass with some really professional results.
wendelclement, I couldn't agree more brother! It is a great bit.
You made a really beautiful design layout with the text and script. The choice of fonts is awesome, and that is not easy at all to find the right ones that say the right things.
Jeff, I'm glad it was helpful brother!
Whoa! How did I miss this one... a year ago. I was probably on the road driving to your place 🙂.
Probably. Naw...this was long before we talked
Have watched several of your posts. Thank you!
Hey Chris. you're welcome
Well done sire ! turned out pretty cool !
Thanks Bruutt! Yes, I think it did too.
Great work.
Jeff, many thanks brother! Happy cutting!
cant wait to try a dragknife.
They do amazing jobs on glass.
Amazing Garrett
your awesome
Keithy, thanks so much! You rock!
Thanks for the video. Nice to know glass can be another material to work with on the cnc.
Yes, this was a nice surprise! the diamond tool works well
I dont mean to be so off topic but does anybody know of a tool to log back into an instagram account?
I was stupid forgot the account password. I love any tricks you can give me
@Casey Jaxtyn instablaster ;)
@Marshall Korbyn thanks so much for your reply. I found the site on google and I'm trying it out now.
Takes quite some time so I will get back to you later with my results.
@Marshall Korbyn It did the trick and I actually got access to my account again. Im so happy!
Thank you so much you saved my ass!
Very good👍
Thanks Don!!
All I can say is 'Wow.....'
Hi Michael. Pretty cool, huh?
man this is fun,thanks.
you're welcome, my friend
Looks good. If you have uneven engraving depth from one side to another it's because you are failing to compress the bit into the spring. If you don't have your depth where the spring is partially compressed it can't compensate for uneven surfaces like it's designed to do. Even the best CNC beds have some variation in flatness. I compress my drag bit by 7mm (out of the 15mm total) and the tip pressure is very constant on un-flat surfaces. This feature becomes even more important when engraving surfaces that aren't very flat.
BTW.. if the pressure is too high after compressing the spring, just back off the tool's adjustment screw a little bit.
Tralfazy, very good points my friend. Thank you for sharing your wisdom on glass engraving.
@@IDCWoodcraft I hope it's helpful. I spent a bunch of hours looking at bit pressure and measuring it. WidgetWorks tells people to set the z height to zero and never even mentions compressing the spring. Hard to understand how the manufacturer of a compression drag bit could get that wrong!
Carbide Create recommends that people compress a spring loaed drag bit 1/4 inch. (5mm) which should be fine most of the time. I use 7mm to put it at near mid-range. I loved your eagle engraving video and have been putting a similar one on all sorts of things. It was when I tried to put it on a rounded surface (flashlight) that I discovered the need to compress the bit into the spring more and started measuring bit pressure.
For contrast, I've been using Gravograph CNCs (IS400s specifically, but I've a little experience with IS8000s, Vision and Omni CNCs) for diamond drag for twenty years and found that on those CNCs 1mm compression with 3mm Z travel on flat surfaces works well. For these machines the spring is in the spindle rather than attached to the diamond bit - but the principle is the same. But these CNCs have much smaller bed sizes than the one in this video.
I judge pressure by pushing the bit with my fingers and for my circumstance (mostly engraving into soft metal) have never even thought about measuring it.
That being said we've never used the diamond drag method on glass (hence my interest in this video) as it is considerably slower than CO2 laser. We also use sandblasting for some glass items. But if all you have is a CNC - then by all means. A CNC may also produce an effect that you, or your customers, prefer over other methods.
The software used looked a bit clunky due to the high number of steps to create the design and get it ready for engraving. The default software for Gravograph (Gravostyle) is also clunky. I find I do much of the design in a more general programme like Blender, GIMP, and Inkscape. I like to use the engraving software just for simple jobs and for sending artwork to the CNC. A more general programme has more features and tutorials due to a bigger user base and bigger development budget.
Very interesting. Iv got an e4 myself and was wondering about doing glass never knew about a drag bit thanks
Hi BG. Yes...it has turned into my favorite thing to do on the router. Check out this more recent project I made a video about with the drag bit: th-cam.com/video/TvmUO3Cvxmk/w-d-xo.html
@@IDCWoodcraft thanks will do. Is there other types of bits that will work with the router? I know I used to do it by hand with dremel bit wasn't sure if there are similar bits for a bigger router like what's on the bobscnc.
@@BG-hg7cp there are many types of bits that do lots of things. Too much to cover here. I'll be adding this info to my website soon. Watch for a video I will be putting out in a couple days. It'll get pretty deep into some of that stuff.
@@IDCWoodcraft ok will do thanks for the reply. Iv been using an e4 for about a year now and just wanting to try more ideas out with it. On my other channel (linked on this one/ is several videos iv done over the past year. Still lots to learn but so far it's enjoyable.
@@BG-hg7cp no link to your channel
I have a question…I used my diamond tip bit for engraving on uneven slate. When it moved to lower area then came back to higher area it bent my diamond tip but. I did straighten it out some but was afraid to be too aggressive to prevent breaking it. Is there a way to salvage it since it’s a $50 bit? Thank you
Anecia, I am not too sure on that one! Your best bet is to reach out to the bit manufacturer on this one on how to salvage it.
Nice job. I like the way it looks. Are the coffee shop owners pleased?
Thanks Rob. More than pleased. It was a surprise gift. And it generated business. Everyone won.
@@IDCWoodcraft Cheap advertising. Best thing to do.
Garrett, I just am starting to try using the Wigetworks bits I bought through you. I was just looking clarification on generating the tool path. Which bit to use in the data base etc. I have 2 bits in mine, both are listed as diamond drag. The feeds and speeds etc. I got when I purchased the bits. I will be experimenting. thanks for any pointers or if you have a newer utube that discusses the subject. I also viewed you eagle project, with the sonagram.
Charlieearle, try using both bits in your database and see what works best brother! The Quick engrave toolpath is best for engraving such as this.
If it's possible ; I would love to see the same work with real song (not with music) but on marble please!
THANKS
Slim, I will look into doing this with marble. Thanks for the great video idea brother!
Thank you for the video. Would this be the same bit used on acrylic?
Hi again Maraget. Yes, this bit is used for acrylic when engraving. What kinds of engravings are you hoping to make?
Getting ready to try my hand at acrylic engraving for some LED signs for my kids. DO you think I should flip the design like you did for the glass or can I leave it as is for the acrylic?
Hi David. Flipping it always leaves a better impression on the front. So yes you should.
Not sure if this has been asked and answered already, but would these types of cuts be equivalent to scoring glass for the purpose of cleaving/cutting? Thanks for the video.
Aaron, great question. The simple answer is yes but it is challenging brother! Look up cutting glass on a CNC, its a bit more involved than what I can help you with in a comment box brother!
I have a 2Link engraver, will the one you used fit the 2L? Great job. I would like to see the setup in Vcarve Pro. Thanks Garrett
You will need 3.5" clearance for this bit. I don't know if your engraver has that clearance.
@@IDCWoodcraft 6'' span
@@jamescullins2709 6"z travel?
Have you tried engraving on aluminum plates? do you think the Evo4 would do a good job on aluminum?
With the diamond engraver, absolutely. I have not but will be doing it shortly. I'll shoot a video on it when I do.
@@IDCWoodcraft I look foward to that video.
What profile do you select in vectric? Surely it can’t be v carve?
DerekJenkinson, try the "quick engrave" toolpath in Vcarve brother! It works great for glass etching.
@@IDCWoodcraft guess which function I've never noticed it used before! 😂 many thanks.
Does the bit spin while engraving? Or just drag?
Hi Karl. No, the spindle stays off with this bit. Just drag. When someone talks 'drag bit', the spindle is always off.
Curious at what depth do you engrave the glass?
tpsooner7816, try setting it to 0.050" brother! The spring loaded tip will take care of the rest.
Have you heard of the MC Etcher by Carbide 3d? It's another diamond drag bit but a fraction of the price of Widget Works! I'm curious to know how the 2 compare. Hoping one day I can afford the Widget Works, but for now it's looking like the MC Etcher..
Landon, I've heard of this one from EC Etcher but haven't tried it out myself. If you end up getting one, let me know what you think of it. I will say the Widget Works will be a tough competition but I will always keep an open mind!
Also will it work on acrylic
Yes
Looks real good to me how much is the bit
Paul, it's an awesome bit. Here's a link to their website → bit.ly/2WR5mVl.
Being diamond tipped, does it work with a touch probe?
Thefilthelement, great question! No it won't because it is not conductive!
I have 6090gz cnc wondering if I can cut glass
Cal for, that machine should be able to engrave and score glass for cutting no problem.
Could have shown toolpath info, depth of cut?
David, check out this video brother. It has all that info: th-cam.com/video/TvmUO3Cvxmk/w-d-xo.html
Hello can you please share your settings you used in vcarve?
Hi Dameion. The settings are listed in the description of the video.
@@IDCWoodcraft my apologies I didn’t see that
Trying my first engraving with the diamond 90 deg bit. When I select profile the bit doesn't exist. Do you have a current drill library that has it. It is interesting that when I bring engraving tool path I can select the drag bit 90 deg. Any ideas why?
Thanks Dave
Dcar1234, great question. You'll want to use the engraving tool path and not the profile tool path brother!
@@IDCWoodcraft thanks I was wondering about that. I was watch your video and you selected profle and it make me think that I might had to use that tool path .
@@IDCWoodcraft sorry one more question. Vcarve or quick engraving toolpath?
@@dcar1234 engraving
can we engrave on tempered glass?
Hey Scott. Yes, as long as you use a spring loaded bit.
I can't see if you're running the spindle, or is it off?
ChristianGchackmool, the spindle/router is off brother! Very important that you do that!
What feed rate and DOC did you use?
Hi Stacy. I forgot to mention that in the video so put it in the description. There is a lot more info in the description as well
Feed 30ipm
doc 0.1"
SPINDLE OFF
I also jusr post a video 2 days ago doing another glass engraving project. Here it is: th-cam.com/video/TvmUO3Cvxmk/w-d-xo.html
Awesome thank you!
How long does the bit last?
John, for glass it should last about 50 hours worth of engraving. In plastic its a lot more than that, in harder glass its less than that. You can pick up replacement tips too!
I’d like to see more videos on drag engraving, design considerations, and tool paths
Well, you told us the length, width and thickness of the glass you used, but you never gave any toolpath settings. It would have been nice to know the depth of cut needed to determine the pressure on the diamond tip and perhaps the cutting speed used (inches per minute).
Hi Bill. I'm sorry about that. I caught it after the video was done and uploaded. Whenever I miss things, I always put iti in the description. You will find it there.The manufacturer of the engraver sends this information with it as well. Here is the link just in case: bit.ly/3tRy98s
What are your thoughts on this project for a first time?
I thought this was pretty cool to do
This is awesome!
Pls sir give bit
