Very good video I learned a lot from it. Thanks
Thank you for such great instruction John. This is the best vcarve video that I have watched.
Absolutely fantastic video. The explanation of how the different v bits relate to the line widths was really helpful.
Thank you for taking the to shear this effect with us John.
Well, you did it again. You managed to teach this old guy something else I can do with my XXL. Great job!
Once again you've helped increase my proficiency. Clear and direct; excellent instruction. Thanks!
I really enjoy the videos you put out! I use carbide create and your tutorials have helped me so much.
I always wanted to hear that from someone before i wasted a lot of workpieces. Better late than never. Great Job
I learned something new. Thank you Clark!
Great to see a new video. I learn so much from your tutorials.
Thanks. Sorry these seem to take me so long. It's more a labor of love than an occupation. I will keep pushing.
Great job John Keep the videos coming
I have watched all of them. That rose would look great on the top of a Heart shaped box.

Thanks for that demo John, as others mentioned already...awesome. I have the same dose file and have vcarved like the left one for .twisted outlaw, I mean in law and turned out fantastic, but I really somewhat one on the right, I never thought about doing it like that let alone knowing how to do that. So thanks so much for sharing that, I'll be trying that out in due course. Andrew, ps videos are always awesome!
Thank you for the great videos.
BEST- THE BEST video I have seen so far. I have sat through 2 classes and it was not explained like this! NOW I get it! Thank you!!
Thank you! That is always the nicest thing to hear. :)
Very nice detailed tutorial. Thank you sir
Love your videos. Keep them coming. Carbide Motion now supports bit changes for jobs created in Carbide Create ( and Vcarve if you use the custom tool change post processor).
Freaking awesome video Thanks John!!!
I needed this video.
Great info there, thank you so much
Add a third V-carve to the raised pattern with a shallower cut and that would have really been interesting. Thanks for sharing these techniques, they are very helpful.
Awesome video.
Thank you!
Amazing
thankyou
Wonderful
Thanks!
Perhaps you can make a video or explain how you pick your bits and or where to source them?
yep found it,
Thanks for your help on this type of v carving. Question. How did you come up with the distances for your offset?
With a 90 degree v bit, my depth will always be half the width of my offset. From there it’s just a matter of how high above the surface I want the design to be: for example, if I want my design to be .2 inches high, my offset needs to be .4 inches around the original design. The inner offset for cleaning up the rest of the piece will always be the same as my depth, in this case .2 inches. Does that help?
Awesome video. Thank you so much. What wood was that? I thought you said MDF, but you got a really nice finish on it ?
The box at the end was done in red cedar and finished with mineral oil. The rest of the video was MDF.
Thanks for this. I can never find the right depth settings when vcarving. I end up eating up all the details. If I barely set depth say 0.03 or so I get just surface tip ?? Any help would be greatly appreciated
So it's a little confusing, but the depth (at least on Carbide Create and I think V-Carve Pro) is a Max depth. This is to keep this bit from diving through your board if the lines are too far apart. So for example, Let's assume a 90 degree bit since the math is easiest. It is going to go about half as deep as the distance between the two lines. If you set max-depth at 1/2 inch it will still only cut all of the details as expected, but anything that would cause it to cut deeper than 1/2 inch will be ignored. The rest of the carve depth will always be dependent on the distance between the two lines you cut between. Does that help?
@@johnearlclark yes it does. thanks so much. i'll keep practicing. I really want to use the vbits more. but so far on my 8 to 12 inch x 20 to 24 stock sizes, i gouge out my details with the vbit
Hey john how are you? I need a bit of your help once again how do you do a clean out pass ?
Thx a ton. I’ve had my xxl for a couple mos and I keep having questions. The first outside distance was the same as depth?
Yes. The idea is that when you vCarve between the rose and the outside line, that inner line is where the point of the v-bit should go. You want to match the depth so that the follow up cuts with the flat bit are right to the edge of where the v-bit tip travelled.
I can’t thank you enough. I messed around with a current design and had it planned correctly. Thx again. Please keep making videos. Another thing I’m struggling with is downloading more fonts to carry through to carbide create
@@mattl1758 So one thing that makes me a little crazy is the font menu in Carbide Create. At first glance, it appears to be in alphabetical order. However, if you scroll down you will see that it goes past the Z's... to a second group of alphabetical fonts... and a third... and a fourth (at least on my machine). If you load in a new font into your system and can't seem to find it, scroll down and see if it ended up in one of these additional sections. (I really wish it was a searchable selecter field)
Depth of cut and max depth in carbide create for v bit?
This video is a keeper in my collection.
But, I watch many videos and it took me a while to learn to set the max depth to the bottom of the wood and the program determines the rest. it seems every one leaves that part out and takes it for granted not to mention.
But however, if you have a comment on that one I would like to learn when NOT to do that?
I have done this both ways. I got used to setting from the top when I started out, but setting from the bottom is definitely better in terms of repeatability and not marring the spoil board. I think in terms of v-carving or recessed design work, I still like to set from the top to make sure I have the exact depth I want. Honestly, a lot of it is down to how your brain works. Some folks visualize the the design better one way or the other.
Great video! So do you set your max depth the same as the width of you vbit?
Carbide Create has two kinds of V-carve paths (Regular and advanced). The regular one just uses the width of the line to determine depth. If its a 90 degree bit, the depth will be half the width between the lines ( a 60 degree bit will be deeper, but I don't know the math) When the lines of an object are farther apart than the max width of the bit, it seems to cut only to the max cutting depth of the bit, while still carving out to the edge of the lines. It can be a little hit or miss for big objects like that. The Advanced V-carve lets you set a max depth and also lets you set an area pocket tool, a flat end mill that will carve out the bottom areas the vBit doesn't reach. I believe you need either the bit setter or some depth collars on your bits to use this option. Does that make sense?
@@johnearlclark Yes Thank you very much. I was doing that and making good cuts in the beginning but then they started going bad. I thought it was me but I think my settings may have changed without me knowing. I went in last night and reset my setting in Carbide Motion and the cut I made seemed much better. Not sure what happened but I think I'm back on track. Still tricky to pick the correct bit at times though. I really appreciate your help!!!! Killer Tutorials!
@@rrshoeing Glad to hear you are back in the groove. I think bits and setting toolpaths is the next video I will have ready. Fingers crossed as it has been a weird year. :)
@@johnearlclark That sounds great! Thanks!
salut et merci de votre temps passe.j'ai une question le moteur de broche Z de ma cnc3018 fait trop de vibrations comment le rendre plus stables ????
I am not very familiar with the CNC3018, but I did find this on another channel: ruclips.net/video/bbvgB_-NqYs/видео.html It looks like it might work for you.
how can i choose the sutiable v 90 or 60 or45 ? the left is deeper than the right why
Carbide makes a good V90. The others I just ordered off of Amazon after reading a few reviews. When you say the left is deeper than the right, what part of the video are you referencing? If you mean the main image, the video explains how the two designs are cut. The one on the left is a standard VCarve and the one on the right uses some extra steps to create a raised effect.
John I realize this is an older video but I just found it. It appears the rose file is not available on Etsy any longer. Any idea how to find the file?
I would probably try a search for "Rose SVG" and see if you can find something similar. That basic concept should be the same. If you run into problems just let me know.
Would you at sometime be able to show this with razed words or is that not possible?
The principle is basically the same: Two outset paths around the word, one half the distance as the other. The only difference is for the insides of letters like "o" and "e" you would also want to do the opposite and make paths inside the letters at similar distances. You might have to fiddle with those inner cuts to make them work right, but the basic technique is the same.
what software were you using?
This is all done in Carbide Create , which comes with the Shapeoko CNC.
Dude wait - does your router not prompt you to change bits in Carbide Motion between those different tooth paths??
When the video was made (two years ago), I did not have the bitsetter on my machine. This was how things were done in the long ago times. :)
@@johnearlclark ah! I didn’t realIze that prompt was part of the bitsetter’s functionality.
how do you get the group in icon?, it is not sowing on my computer, mate
It only shows up when more than one item is selected. If you are selecting more than one item and it still does not show up, let me know which version of Carbide Create you are using and I will check into it.
Cut_Depth = Cut_Width / tan(Bit_Angle / 2) / 2
So, the depths for each bit when they reach 1/4 inch cut width...
V-90: 0.1250" (1/8")
V-60: 0.2165" (7/32")
V-45: 0.3018" (19/64")
How to get the formula...
A Bit_Angle forms two right triangles having angles equal to (Bit_Angle / 2). (The Cut_Width / 2) forms the base of each right triangle that will have a height equal to Cut_Depth. If you draw this out, you'll see that you're dealing with "opposite over adjacent" which is the tan function (tan = opposite over adjacent).
tan(Bit_Angle / 2) = (Cut_Width / 2) / Cut_Depth
Cut_Depth * tan(Bit_Angle / 2) = (Cut_Width / 2)
Cut_Depth = (Cut_Width / 2) / tan(Bit_Angle / 2)
Cut_Depth = Cut_Width / tan(Bit_Angle / 2) / 2
I did the rose perfect ty I am new to cnc I tried to do eagle from Etsy but not successful
Where did the eagle seem to go wrong? I would be happy to see if I can figure out a solution.
John Clark when I try to do the offset etc all heck brake loose I can send you the eagle svg by email if you want
@@athanasiospersopoulos1499 Is there anyplace you can post the file so I can take a look?
John Clark I can send it by email if you want
@@athanasiospersopoulos1499 That works. Just use the business inquiries email on the channel About page.
Approximate cut depths for V-60 and V-45...
V60: Cut_Depth = Cut_Width * 0.866
V45: Cut_Depth = Cut_Width * 1.207
...or...
V60: Cut_Depth = Cut_Width / 1.155
V45: Cut_Depth = Cut_Width / 0.828
...derivation...
Cut_Depth = Cut_Width / tan(Bit_Angle / 2) / 2
Cut_Depth = Cut_Width / (tan(Bit_Angle / 2) * 2)
Cut_Depth[v60] = Cut_Width / (tan(60 / 2) * 2)
Cut_Depth[v45] = Cut_Width / (tan(45 / 2) * 2)
Cut_Depth[v60] = Cut_Width / 1.155
Cut_Depth[v45] = Cut_Width / 0.828
Cut_Depth[v60] = Cut_Width / (1 / 1.155)
Cut_Depth[v45] = Cut_Width / (1 / 0.828)
Cut_Depth[v60] = Cut_Width * 0.866
Cut_Depth[v45] = Cut_Width * 1.207
Great videos, Hate the music, in particular the increased volume!
