Let’s Carve This Simple 3D Eagle on the CNC

Hello, welcome to today's pop-pods workshop on v

carve

pro. I'm starting 3D carving for you. Now I want to be able to take a very

simple

project like

this

and go from the beginning to the actual conclusion of the project and show you. how easy it is to do 3D carving, it's not that bad. Now I'm not going to go through every little icon in vcar pro, but I will show you the ones that are necessary to get you up and running, so let's get started. I started in the recent videos that I made, I stopped asking people to like, subscribe and share the video and those algorithms just took a nosedive, so please, I'm going to ask again if you would help me be able to drive. the algorithms and if you are new to the channel, press the subscribe button and the little bell next to it so you can receive notifications of the various videos that I upload and like and share

this

when you like the video.

It's helpful to boost those algorithms so we can get this video to all kinds of different people everywhere, so help me by subscribing, liking and sharing this video, so let's get back to today's project. What I want to do is show you how. We can actually

carve

this

eagle

head and this is by far the

simple

st 3D you can do and I want to show you how simple it is and then we'll go to the CNC machine and carve this project. so what I want to do is start with a new page so I'm going to close, well, let's do this.

I'm going to click New and no, I'm not going to save this, so here we go, we're on a new page now this project is going to be done on a piece of wood that I have and it measures eleven and a quarter by nine and a half, like this that those are the measurements that we are going to use and they are three quarters of an inch now we are going to stay in inches today and as for the zero z position, I will keep it on the surface of the material and for this design today we are going to use the center point as our reference position the software. help generate the project itself, it will not change the way it is actually presented on the screen, but it will change the way it calculates the number of pixels you need to be able to produce the final project and the standard, of course, be the lowest number and it will be able to calculate the fastest and for this one I think I'm just going to select high, it's three times the amount of pixels that will be developed, so it will be rendered three times. slower and then you have a very high level, you can go even higher, but I don't want to talk about that in this video, so I want to select high, Canadian maple will be fine and then I'll just click OK, one of the good ones.

The thing about the vcar pro is that when you bought it you also get a lot of clipart so I can go down here at the bottom and click on that and then I have two different categories, we have a clipart and then we have the design and create , you can go design and create and they have a lot of different projects and things that you can download and buy the clipart; However, there are a lot of them that are actually free and come with the software and you can scroll down. and I look at the different projects and there's a lot of different ones and what I'm going to do today is I'm going to work with the

eagle

s and there's three different guys here I want to go ahead and bring this in and I'm going to zoom it out and I want to slide it to the right, I'm going to bring this little one up here. and I want to reduce it because I want to be able to show you and then the second one and this is the eagle head and this is the eagle. go to b and we'll do the same thing, we'll just grab the little arm, bring it down and slide it up here and then this is c, okay, we'll shrink it down and Keep it on the page now, those are the three different types.

One of the things when you're working with 3D models is it's really difficult to be able to see exactly what it's going to look like, so what you can do is come. up here and you can select this and now you can get a very good representation if you want to see it left and right, you can do it this way. Here's the big difference: This is actually raised off the surface if We're working with a three-quarter inch board, what's going to happen is it's going to cut through the material and leave it higher than the surface around it.

This one is actually on a plate and you're going to cut it and this is going to be below the surface and this one. one gives more of that hand carved look and is also below the surface. What I want to be able to do today is be able to work with this one here, it's my eagle head and it's the b, it's the simplest one to start with and um, frankly, between this one and c for this little one are basically identical, this one is going to take more work to be able to set it up and I'll do this or something similar in a very close video, but for now I'm I'm going to go ahead and delete this, this is the one I'm going to work with.

The first thing I want to do is go ahead and put this back in the center, so what I'm going to do is go to the drawing tab and then I'm going to click on this icon right here and press the center and now it moves it and you notice that it moves them both so you can see exactly what's happening when you're working with the 3D that you don't. I don't want to have a lot of white space around your project, so what I'm going to do is go ahead and let this be. make bigger.

We'll make it bigger today, there we go and then I'll go ahead and center it. again and I actually think I'm going to make it a little bit bigger, okay, I think it looks good when you look at this, this is what the image will look like when you carve it, but there are a few things we need. to be able to do this to be able to get the toolpaths to be able to work correctly and one of the things is we know our material is three quarters of an inch thick, but how thick is this project itself?

I'm going to go ahead and highlight this and we'll go down first, I'll close this and we'll go down to the modeling tab and I'll click on this icon right there and now we can In fact, I see exactly how tall this particular object is, it's 0.6674 of an inch. Now, if it's going to be a little bit too thick, we can change it so we can change it by being able to decrease it like this and it will update and show it to you. The difference and you can see what it looks like when I rotate it or if I want to be able to put it back, I can increase it, that really depends on the overall look that I'm trying to achieve to achieve what you don't want to have.

What happens is that this eagle is above the surface in terms of fade and tilt. I'm going to talk about that in another video and when you look at this and I turn it to the side you're looking at this disc. and it looks like it's floating and there are no real landmarks here for the computer to follow. I'm going to put this back into this mode, so what I want to do is basically show a zero board. So this will actually simulate if you want the surface of the material, so I'll go over here and click on the modeling tab.

This is added to the zero height and that's where this surface is placed now, when you look at that. It gives you a reference to follow and you can look down at that line and it looks pretty good, but is it a little proud? Let's take a look, let me back up and come back here to my height and now. You can see when I put this zero plane here, the actual height is 0.593, the maximum z height is 0.593 and this maximum is 0. That means it's below the surface, so at this point I'm ready to set up the tool paths now .

In a project like this as far as tool paths, you could actually do it in one tool path, but I'm going to go ahead and take a look at how to do it with two, so I'm going to go ahead and click on this one right here. Go to the tool path and the first one I want to see is this roughing tool path and it has a quarter inch in milling configuration and I happen to have a quarter inch end mill so I can select the what do I want. so I could keep this with the model limit and that model limit will be set right there, if I had put a vector here I could have picked a selected vector and that vector would have stopped it as well, but this should work fine and as for the limit of displacement, I think I'll put it around .04.

Now what that will do is that part will go all the way to the edge, but it won't go all the way to the end. edge, the finishing bit will take care of the next frame is the machining allowance and this is also set and this was by default at zero point four, which means that while doing the roughing pass it will leave zero point four of the material still there so the finishing bit can go through and clean it up to this roughing strategy. You can go with the z level and it will just make its way through or you can go with the 3d scraper and go in that direction.

Leave it this way and we'll take a look. I don't need to do the ramp and the dip, everything is fine, so I want to calculate this, then we'll reset this preview and I want to set it up and that's it. what it's going to look like so it takes care of the roughing pass and now I want to close this and let's go back and select the final pass. This has an eight inch ball tip and that is the only ball tip I have. let's use that one, this is going to be with the model boundary again, this time we're going to have zero offset, it's going to carve would be the offset, let's take a look at what it's going to look like and this is the 3D Finish Pass and let's calculate that and you'll notice that it takes a little bit longer to calculate because we have it on the high setting and at this point let's reset this preview and there we go, this is what it's going to look like if I don't do it.

I don't want that, let's double check, let's click on that, let's do the scraper strategy and we can do the zero angle and let's calculate that and there we have it, so we'll reset this and this is what it will look like, it will start at the bottom. and work my way up, now what I'd like to do is come back here for a moment and highlight this and I want to go back to the modeling and I want to be able to put the vector in and then I want to come back and take a look at what happens when I have it calculated, so let's go back to the roughing step, we'll look at it and this time we'll select the vector I need. to select the vector, although there we go, we select the vector, we still keep our assignment here and we'll go ahead and calculate it now and now you can see exactly what's happening, it will keep that 0.04 off the surface. let's reset it and carve this, there you go, let's go through the final pass and we're going to do the selected vector on this one and there's no limits here and I think it's going to look good, let's calculate that right and now let's reset it. and preview it, so I think it will look good.

I'm going to go ahead and save them and we're going to go to the machine and carve this now, the only thing I want to be able to see as well. is to see how long it's going to take to carve this so I can go back and click on this, it's going to take quite a while, it's going to take about three hours to be able to carve this, so if I come back here and let's go ahead and do the roughing pass again and we'll do it with the selected vector, we're going to keep them all the same and I'm going to go ahead and calculate this, let's change them because I certainly would We want the roughing pass to be done first, so now we have the roughing pass and then the finishing pass.

We'll close, check our time again and see if that reduced the time. We'll close this. We'll go back to our time and it's still showing the same time, but it adds the time for the preview pass and then it adds the three hours and 24 minutes, so I'm going to go ahead and delete that preview pass and I'm going to do this with just one bit, okay, I'm going to rename this just an eagle so I can find it easily and that's going to be the 3d finish and we're going to recalculate this anytime. If you make any changes, just go back and recalculate and I want to do this so you guys can see what it looks like.

I think it will be a very pretty eagle. Let's close this part. and save the tool path and this post processor is okay so I'm just going to click on save tool path and this will be eagle 3d now we have the x position and 0 in the center so I'm going to go ahead and mark an x ​​right in the center of this project board, so this is going to be my initial x y zero position right there and I think what I'm going to do because we're doing the circle in this area, I'm just going to go ahead. and screw this into all four corners because it's not going to move outside of that circle now, the times when I use these screws to be able to attach it with this mdf, it's actually going to raise the surface and you can change the height of it.

So one of the things I do with that is after I'm done with the carbon I make sure I take a chisel and just hit off those high points so I don't have that problem so I'm going to go ahead and set this up right here on the line that I set up on my machine where I use the zero x and y position this way I know it's square and then I'm going to take the screws and screw it in and two should actually be enough. I'm not going to put four in there now. This is the drill bit I'm using.

This is a one-eighth inch spherical tip. These two. flute and this is an improved snippet, one thing I didn't mention and I'm sure there will be some questions about it so I'll go ahead and answernow and I'll try to mention this again somewhere else in the video, but this part about a step over when you're doing the 3d is actually very important, you need to have a step over between eight and ten percent so far much less. because you need to have that overlap and that's part of the reason you add so much time to carving.

I'm using ugs which is a universal gcode sender so I can carve this, I just opened it and now I'm good to go. to press open and then I'll get this little alarm code and I just press the dollar sign on the x and that will clear it now from there I want to be able to go ahead and move my machine to my Home Position x and zero, I'm not going to use my three axis touch pad, what I'm really going to do is go ahead and align this with my x and zero position and then I'm going to use the z probe to probe and get the zero point for that bit.

Okay, now I have the bit directly over my zero position x and y all I need to do is reset it to the ugs as my zero point. and I'm going to go ahead and lift the bit every once in a while we'll do the z probe, so in my working position right here, this is what I need to be able to do is just press reset my x reset my y and that changes it to basically zero . Now I'm going to go ahead and do the z probe next now that we have it in place.

I'm just going to go to the macros and this is the one that does a z probe alone, so I'm going to to click on that and that's it, now it's complete, so we can delete this to get it out of the way and that takes me right to my z position, so we're ready to be able to carve the next thing I'm going to do. go to file mode, open the file, I just go here to my v car project files, click on my eagle g code right there and I can press open and you will see it appear directly in this window, now I go to come and access to my visualization so we can see what it's going to look like, so I just click on that tab there and it's going to take a minute until it shows up and it shows this yellow right in the center, that's where it is. it's supposed to be and then it will happen from there, so that's exactly what we wanted to be able to see, so we'll close.

All I need to do now is turn on the machine and press send, so now the actual carving time was one hour. and 50 minutes, so I'll go back and see if I can adjust that in the vcarve pro. Now I want to show you this here, this is a little flat spot that was on the carve and that can be easily adjusted and I'm going to show you in v-carve and I'm going to go back and open that up and show you and all we're going to do is lower the height. of this eagle a little and that would solve that problem.

Now I want to show you something else I've noticed. If you notice that here on this side there is a small groove that is not seen anywhere else on the project and that is an indication that this side of the project was raised a little bit and that is what I was referring to earlier when you use screws to hold the project, if it lifts up slightly, then you can get that kind of groove, okay? in the project I want to go and highlight this and you'll see the little blue dot right there, the little blue square, I can highlight it and that opens up this modeling tab.

This is the height of the shape and everything I need. What I can do is adjust that instead of 0.6997, I can lower it to 0.69 and that should be enough if you want to lower it a little bit more just to be safe. I think I would go to 0.6 and then for sure. I know it would be below that, so I'm going to go ahead and update everything right now and then we can take this and rotate it and you can see it's actually going to be below the surface this time, that's how easy it is to be able to make that adjustment, so this is the First 3D carving I've done with this setup and it turned out fantastic.

Now there's no need for sanding, it's straight out of the machine and I think it turned out great.
