Two Huge Signs to Make Using Tiling on the XCarveJun 25, 2021
Hello, welcome to the pawpaws workshop. I'm making two big
signstoday. They're about 20 inches wide and 42 inches long, which means I have to tile them on the CNC machine, so I'm going to show you how today. But I also need your help. I have a lot more of these things to do with all the different types of fan art. If you like the videos, please let me know in the comments so I can continue this series. i know that too and we will move on to another project and i will continue to
signsbehind the scenes but for now i want to show you how i made these two big big signs by stacking them on the x-carve so let's go ahead and get started these signs were very hard to
make, although it was a lot of fun to be able to carve well, new day, new project and today I'm taking the word daredevil and right now I'm in inkscape and it just did the tracing bitmap and to be able to do that go up here to the path and select the trace bitmap, click that t and then just follow the steps here.
I just narrowed this down to the two colors there. Press OK and bring it up. This is the image I have. The original image that was given to me was removed and is now done. to be able to save and bring to easel now, I opened easel and brought new word to easel. I just import it and all you do is upload to the import file to SVG and there it's fine nothing special there but what I need to be able to do this is actually about 40 inches from this point to this point here and obviously that's bigger than the machine will be able to cut now this is going to be 3D I'm going to cut the letters out of quarter inch MDF and then I'm going to cut the base that will outline this half an inch now I've opened a new window so I can do this and i copied and pasted daredevil into that window so the next thing i'm going to do is go here to apps select that drop down to scroll or app c lick that and this comes up now what i want to be able to do is outline this to about 1.5 inches so it looks like this so from there there's nothing else I need to be able to do and I just go ahead and import it into the layout so here it is in my piece of work now and how important it needs to be to give Realizing these letters are going to break and I want to be able to just grab this and build it and move it out of the way that's what I'm going to cut these letters will cut as individual letters I also went ahead and rotated this 90 degrees and I'm going to set this up where it's going to cut into the half inch piece of the MDF and I'm going to tile it so what I need to be able to do is place it down here in the corner so I can get the exact location and then this little dot right there, I think that would be a good place so I'm going to set this up so I can tile it and first I'm going to cut the bottom half and then I'm going to slide my board down and cut the top half now back to the original words next thing I need to I can do is go back to the app and I'm going to select that and this time we're going to select the exploiter and I want to be able to split these letters into individual letters so it's accomplished with that I don't need to change the spacing or anything else , all i need to be able to do is select the import and bring that back now it comes with this little box the layout is bigger than the work area and that's fine so i'll leave the original and now these are highlighted and these are individual letters from there all I want to be able to do is select each individual letter and pull it out because I'm going to arrange it to fit on the smallest board possible to carve now let me show you that the other thing I want to be able to do is take these letters and I'm going to change the outline and I want to cut to the outside and for this I'm NOT going to use tabs so now I opened another window and put the word reckless on it and then rearranged them to fit in the smallest space I could get so I'm going to go ahead and set up the machine now so that it's able to carve the letters first and then we're going to move and cut the background second now because I'm going to cut all the material.
usingthe glue and tape method so I took a piece of masonite and with the tape and on the Star Bond glue I went ahead and glued it to the table that way when I cut it it will protect the waist board the glue I'm on
usingtoday is Star Bond medium CA glue and this works extremely well now we will put a link in the description. I was recently offered the opportunity to offer you 15% off so in the description below I have a discount code that allows you to purchase the Star Bond glues for 15% off it's ok to be able to cut out these letters this area goes g to be 23 by 23 now I have it set to a half inch so I need to go in and change it so it's currently set to 0.5 of an inch and then what I need to be able to do is change this to a quarter inch with the calipers, I measured the material, it's actually 0.24 thick, so what I'm going to do is change this and go with 0.26 and that way it'll cut through all the material. see what it looks like in that preview what i actually did is write to point 0 to 6 and then when i came and tried to adjust it here and put 0.26 it automatically changed it to point 0 to 6 so i had to do that adjustment before carving is ok now i have everything set up and this is a preview of what it looks like and you can see it will cut all the way through and again i am not using tabs for this which is why i am using the glue and tape method and so it is as seen on the other side of the screen.
Now I'm ready to continue. d and cut my board 23 by 23 and place it on the C&C and start carving hey I have my quarter inch MDF and I'm just putting up the fence for the 23 inches and I'm going to run it through the table saw now that I had the guide on already , I was just checking one last time measure twice cut once and the other thing I had done is adjust the saw blade and I brought the blade down to where it would be just above the height of the material itself and that's how more secure to be able to cut the material and with the first piece cut I just flip it over and cut it again and that makes it my 23 by 23 square now the next thing we do I want to make sure the top and bottom are secure real good , they don't want to look at the letters, the letters at the bottom need to be secured, but then the letters here in the middle I need to have multiple pieces to glue together, so I'm going to go ahead and put one more. here that way it'll hold those lower letters right now so to get these little letters in the here in the middle, I need one to go through this area before I put the tape on the table.
I'm just checking on the computer screen exactly where it needs to be right so that's where it's going to be now then I have to put the tape under it and the first piece of tape goes right across the bottom which will go right there the second tape will go right here and then I'm going to have a piece here there and there okay so we'll just slide this out of the way what I'm going to do is just put the glue here flip it over place it in place and square it now again. for this not a bad deal so just a row chit Rose i think i'm going to add a little bit more here just to be safe and there we go we'll give you a chance to drive for a bit and i'm going to go ahead and set up Athens , this will be my xy0 home position for my work piece zero now I'm going to go ahead and set my X Y zero home position right now and I'm going to do that first so bad will the location be there so now what I'm going to to do is move it i can do the z axis so much give my z axis right there at that location now i set my x y zero point first so i can get the bit close to the surface and make sure my alignment is exactly where i want it once done this I can move the router to any location for the Z so to measure the material is correct the thickness I set it to 0.26 of an inch the actual thickness of the material was about point two four so it should be cut complete ely the material is clamped and secured it won't go anywhere, in fact you probably used too much glue.
I'm using the eight inch straight bit so I can do this carving and now we're going to go ahead and probe the clip attach this let's go ahead and make the contact we got it and we put it exactly where it needs to be and we'll go ahead and test it's done , the z axis is done so now what I'm going to do is click set X y 0 and in order to do that I need to move it back. to this position and there we have it now we're at zero X Y position so I'm going to click on that and we'll turn this axis on and start cutting the letters.
Now the feed rate on this started at 40 inches per minute and I realized that was really too slow so by being able to do the adjustment on the screen I was able to adjust it up to 80 inches per minute and that made things slower. muted a bit faster and still worked extremely well. I wanted to show a really good closeup and you can see how clean it's cutting and you can also see where it's moving F 80 inches per minute cutting through all the material, that's what I wanted and you can see how nice. the tapes holding there is no movement at all that is what I have to have to be able to have the necessary precision for these let ters now one thing that I want to be able to point out as far as the depth of the cut is actually a very shallow cut and doing multiple passes with this thin material and being MDF, I frankly could have changed that and done this in probably about two passes by cutting it deeper in a drywall cut, but I didn't, so you'll see shallow passes and it takes a little longer, but at The end is done and now it's time I can go ahead and remove this wood now I can remove this just using the putty knife lifting it up and then with my hands it will go ahead and lift the rest of the tape off the bottom tape and it will just lift leaving the letter still on tape and then from there.
I'll just lift the letters and remove this tape and clean my work surface again and I'm ready to go ahead and move on to the next step and these letters will slide off very easily. This is one of the reasons I really like the tape and glue method to be able to secure m and project to the table if you have a stubborn one a little bit of spatula work and it just pops up now the other thing I want to point out and I used an 8 inch straight bit for this and it worked great. Good, and I don't really have to sand, that's necessary.
Some of you might be wondering, what about a down cutting bit? cut a bit and that's going to get the chips out and probably need some sanding so just keep that in mind when you're doing a bit selection and with all the letters removed this phase of the project is done now everything I what I have to be able to do is clear the board of rubbish and prepare for the next phase. Now I wanted to show you what the finished letters look like and again, this is not with any kind of sanding. I went ahead and explained roughly what it would look like in the finished sign and now in the next ep and that's where the tile will be involved in cutting this base and the next question is how do I cut this shape and the reason I'm asking is so this white area is the size of my CNC table so what I've done the steps I'm taking I went ahead and highlighted the area I'm going to carve and that's thirty nine point six by nineteen point one now the easiest way to to do it is just round to forty inches by 20 and that's what I've done here I've set my work area to 20 by 40 and I've set my thickness to point five two inches so that's what I've done here I've set my workpiece I 25 so I can see the line that is the workpiece so I want to bring this object down and center it on the material and that way it will cut all the way to the edge but it won't be off the board so i can undo get over that you'll see you'll get to it now the other thing is just to make sure this is cutting the path and f or this I think I'm going to go ahead and cut this and leave that in the path which will be fine right now so next what i need to be able to do is decide how i'm going to tile this this is a really good point here so what i want to be able to do is set this up and i'm going to carve this bottom half first and then carve the top half and the shape What I'm going to do is I'm going to create another box and I'm going to take that out and make it bigger and I'm going to put that right in that spot and I'm going to light this up to nothing, so what I want to be able to do is zoom in and see exactly where it's going to be this point to this point and that's what I'm going to transfer to my board so I'm going to zoom in and think what I'm going to do what I do is put this at 21 like 20 but I look at this right here this twenty point nine nine.
I'm going to make it a pair of 21 inches now with that done I can transfer that measurement and use that as my point. Then what will happen? Let me zoom out my XY start position will be right here and it's going to carve this part out and then I'm going to slide my workpiece down and my new now so I can show this would be quite capable of simulating anyone enjoying it and pressingstimulate, okay? What are you going to do? We're going to go up here and carve it and then it's going to come home and there's no other places here that I need to worry about right now, now it's very important that you don't skip this. step you want to press stimulate and you want to know exactly where the CMC is going to go because if you make a mistake and you have some objects that are outside of your desired cutting area it could cause a problem and the machine could try to cut outside of your working area you are ok so here is the setup on the table itself.
I have two bit bunk stops that are also taped and glued together that make up my y axis and that will allow the board to slide from this point and it will slide this one to my 21 point line and that will be my new XY 0 now I also have this with the glue and tape to hold it in place so now i'm ready to be able to carve the
tilingoperation like this where the lines have to match up exactly your machine has to be very very tuned now. i know my machine is 100% square but i also know i was slightly outside the lines that are on the grid so it's important to check that i'm also now doing two signals right now this is the daredevil and it's doing the cut and learned a lot about how accurate this needs to be.
The other sign I made was the poison sign and it had the tile both the letters and the board and if your piece of work is as small as 1/32 of an inch off it will make a world of difference with the letters not lining up now. I know this has been discussed many times on the Inventables forum, but you can see the toolpath the ridge is generating and it's definitely not an efficient toolpath because ideally this would have cut the entire line without any movement and then I could go back through this saving a ton of time, but the easel is what it is and gets the job done, okay, here's a new setup.
I have the board compatible with the rest below. This is my 21 inch point right here which is my home to my ex wife zero position and I lined it up with a full vacuum sizzle or Skippy same point I have to zoom in now what I'm going to do is move on . and carve I've got my white box moved down to this position now and for it to cut this portion and here's how it's going to cut along here and you'll see the red line, the red line will come and cut this and then come back right at the part bottom so this is where it's going to cut so let's see how it does it so I move the router to the exact spot from an angle XY suspiciously after C is the key to make them very very precise I'm going to hit the C axis and like I said I've learned a lot doing this project because even though I've done a lot of tiles in the past, accuracy wasn't as critical as it was with this one because of how the letters have to line up and how the backer board now it's time to go ahead and remove this one from the board and again the waist part it just breaks leaving the backer board in place and then I can remove it separately now again like I said I've learned a lot and on the next sign i carved this top first and then slide it along the axis back to the top and cut the bottom so it's just the opposite of what i did in this particular video and that seemed to work much better , the other thing is instead of using a pencil line for my reference. aim for 21 inches.
I actually put a little little box and carved it and that gave me a much more accurate reference point of exactly where the bit was so here's a look at the finished card sign now on this particular sign these letters they're going to be offset because once the color is added the LED lights will be placed behind these letters and it will look really nice but the client will do that part so from my point of view this job is done but one thing i wanted to show you how the lettering would stand up so check this out there is a big difference having the lettering offset i think it will look good once it is full color with a black background the red lettering and the are shown LED lights I can't wait to see this finished sign when the client paints it I don't have an updated video when it's finished The other thing I wanted to show you is this quick look at the sign I made for the poison using the same techniques now new Mind you this sign is 42 inches long and in order to do that both the board and the letters had to be tiled and you can see all the crazy line movement in the letter and that's where the
tilingtook place that's why the machine has to be extremely precise or those lines won't line up and it will look worse than horrible so I think you can see here that it ended up looking fantastic and the other thing that was a real challenge on this poster was being able to send the lettering to the SVG file the way i wanted, it took me a lot of work to achieve it, so i need you to do me a favor, leave me a comment if you like this kind of project, the reason is that i have enough more signs to do this with the various fan art and if you like this, if you want me to go into more detail on how I create these different signs, please leave me a comment below because if I don't get a lot of feedback and interest in making these types of signs.
I'll do them off camera and continue with other projects and not show it so it's up to you right now if you want more of this type of project and be able to see the other logos in all the different types of comics let me know in t he comments below you hi everyone thanks for watching my video today if you liked the video please go ahead and hit the subscribe button below and the little bell next to it to get noticed
