Silhouette Cameo Cutter by Cathy Saxton I got a Silhouette Cameo plotting cutter and have been using it for a variety of purposes. My experiments and tips are below, but first, a story from when I received the cutter. It came in a gigantic box. I opened that to find a bunch of packing paper and another brown cardboard box, about half the size of the first one. (It looks like that was used to ship from the distributor to the retailer.) I opened the second box and found a third box. At that point, my husband, Tom, speculated that I'd keep opening successively smaller boxes until I got to the final one with an X-Acto knife and a ruler. And now the usual disclaimer: I make no guarantees that my techniques will work for you, or that they won't damage your machine, blade, or mat. That said, I hope you find some useful tidbits on this page! The next several sections are some general observations and tips. After that are three sections with steps for a specific project:
Experiments with Rotations when using Registration MarksI was interested to see whether the cutter assumed a perfectly aligned paper, since it's challenging to accomplish this. I created a simple drawing with registration marks and cut-out squares in the corners, then printed it (just the registration marks print, of course). My first several attempts at mounting the page at a noticeable angle failed. I was doing an extreme angle (~1/2" drop over the 11" length of the page) so it would be easy to see whether the squares got cut in the right place (and angle). The first indication that it wasn't happy was that I had to use detect registration marks manually. That worked in one of two cases, but the squares weren't cut correctly; it had correctly accounted for rotation vertically, but not horizontally. For the second test (rotated the other direction), the Cameo failed to find the registration marks. Note that my extreme rotation cases were outside what could reasonably be expected when mounting a page on the mat, so I don't fault the machine for not coping with them. Next, I tried a less extreme angle, more like how a page might be mounted just slightly off, but still enough of a noticeable tilt that I'd be able to measure and determine whether it adjusted for the rotation. That worked beautifully! The picture on the right shows the page mounted slightly askew on the cutting mat. As you can see from the arrow, the top of the cutting mat (first part into the machine) is on the right side in this photo. In this orientation, the 11" side of the paper is vertical and there are squares cut near the right edge, close to the top and bottom. The pictures below are close-ups showing the distance from the cut to the edges of the paper,
sticky area, and mat.
The first photo is the top square, the second photo is the bottom square. Notice
that the distance from cut to edge of paper is the same in both, and you can see how the paper
was crooked, closer to the edge of the sticky area in the lower photo. Measurements along the top edge of the paper were similar, showing that the cutter did correctly account for the rotation of the page. Yay! Conclusion: The Cameo cuts correctly (rotating the design) even if the page with registration marks is mounted slightly crooked on the cutting mat. Compensating for an Overly-Aggressive Sticky MatI found that peeling off a large piece of cardstock was challenging and tended to result in pretty major warping and sometimes wrinkling. In my case, I was making a few small cuts to the card, and wanted to use the card (not the cutouts), so it was a problem when it got damaged during removal from the mat. My solution was to place a thin piece of paper under most of the middle area of the cardstock, in an area that wasn't getting cut. I found that I needed to change my blade setting to 4 instead of the default 3 that had been working fine to cut my (Stampin' Up!) cardstock. This worked wonderfully; the cardstock was still held in place for cutting, but was a lot easier to remove. Thanks to Chris Savery for sharing another great technique that I've been using recently: Place the mat at the edge of a table, with the cut paper on top. Gradually slide the mat off the table, pulling it down and guiding the paper off the mat, keeping the paper parallel with the table. This works well and results in very little curl in the paper. Cutting at a Precise LocationAfter a few trials, it became apparent that I would be unable to get cuts in a precise location on a card by just mounting the cardstock to the cutting mat and inserting it into the cutter (even when placing very precisely on the mat and inserting at a consistent left-to-right location). It tended to vary by up to about an eighth of an inch. The good news is that the "registration mark" feature provided a nice way to ensure consistent cut locations. The next two sections — Integrated Card Stand and Cutting Out a Stamped Image — show examples. Integrated Card StandCards with the fold on top (instead of left) are temperamental to display; they tend to unfold, slowly creeping toward becoming flat. There are nice options for a separate stand that can be used to hold the card and keep it from sliding apart. I decided I wanted to make a card with an integrated stand, so I did some experimenting and designed a system that created "legs" from the back cardstock. The card is a standard half sheet (8 1/2" x 5 1/2") folded to 4 1/4" tall x 5 1/2" wide. The legs are 1 3/4" long and 1/4" high, with the feet extending up to 1/2". Slits in the front are 1/4" long, 3/4" in from the edges. I made prototypes using my trusty X-Acto knife, but used this project as my excuse to get a cutting machine. :-) It has turned out to be useful for other projects, too. Cutting with the Silhouette CameoThe basic strategy is to create a "template" sheet with registration marks and a cutout to provide for precise placement for the card, then use a second file to make the cuts. Preparing the Template
Cutting the Card
Finishing the CardScore the legs where they should bend toward the front.
I put a sticker on the back of the card with instructions. As you can see in the photo above, I decided not to extend the "foot" cut all the way to the edge; that way the legs aren't loose and flopping around. For the front and inside, I cut white cardstock 5 1/4" x 3 3/4". On the inside one, I punched the two lower corners with the ticket corner punch; this matches the arc from the cut on the feet. Cutting Out a Stamped ImageFor computer clip-art, printing and cutting out an image is easy — just add registration marks to the artwork, print, and the cutter knows exactly where to cut. With a stamped image, however, we need to do a little more work to define the relationship between the image and registration marks. We do this by using a template that shows the location of the cut relative to the registration marks. The template will guide the placement of the stamped cardstock onto the cutting mat. We'll create two files: one for cutting the outline, and another to create the template. Setting up the FilesWe'll start by creating the OUTLINE file, then will add to it to create the TEMPLATE file.
Creating the OUTLINE File
Creating the TEMPLATE FileFor the template, we'll cut the outline that we want to use on the card, and then another outline just slightly larger; this will give us a narrow band to guide placement of the card. We'll also cut a large rectangle on the template to provide a large exposed (sticky) area on the mat. Note that the steps below are assumed to immediately follow the steps above. Specifically, it is assumed that the blue outline cut is selected. To verify that, open the Line Color window and make sure that the blue block is highlighted and that a selection is shown around your stamped image. If the blue outline cut is not selected, you can select it by clicking precisely on it; if the blue block isn't highlighted, click on the grid area to remove the selection, then try again.
If you open the Cut Style window, your image should be similar to this: Preparing the Template
You can now use this template again and again to cut out the same image multiple times. But, once you remove the template from the mat, you'll need to follow the steps in this section again; you can't just put the pieces back on because you won't know the spacing between the outline and registration marks. Mounting the Cardstock on the MatTo align the stamped image with the template's guide, I worked from the back of the mat. It's translucent, so I was able to see through it pretty well. The issue is being able to see from the back of cardstock (which will touch the mat) through to the stamped image on the front. A window works well for this. (Yes, even in overcast Seattle, there's plenty of light for this during the day.) Of course, a light table would work great, too, but I don't have one of those. I taped the stamped cardstock to the window with the back facing me (so someone outside would be looking at the front of the image). Then, I held up the grid, aligning it so that there was a consistent gap all around between the stamped image and the template's outline. I pressed all over the cardstock to get it firmly stuck to the mat, then removed the assembly from the window, gently pulling off the mat and tape. This photo shows the image as seen through the mat and cardstock. Note that you can see the
template's outline shape pretty well around the feet. It was easier to see in person. A couple options for alternate ways to mount the cardstock image:
If your image is on darker cardstock, it can be challenging (or impossible) to see through it. Either of the methods above would provide a way to mount those images. Cutting Around the Stamped Image
Cutting Mylar for Solder StencilsWhen soldering surface-mount components to a PCB, I like to use a stencil to apply solder paste and a griddle to heat the solder. I was hoping that my new Cameo cutter would be able to cut the 3 mil mylar that I like to use for stencils, and it worked splendidly! I did some experiments and the Cameo made a beautiful test stencil. The cuts are clean and precise, as good as or better than I've gotten with a lasercutter. In the images below, the larger blocks are 2 mm square. The smallest cuts (top center) are 0.5 mm pitch spacing.
For 3 mil (0.003" / 0.0762 mm) mylar, I was able to get a good cut using a blade setting of 1 (0.1 mm) and Silhouette Studio thickness setting of 33 (max force). With less force, I had just a bit of trouble with occasional shallow cuts. I'm using speed of 1 since I'm making fairly small cuts. This is a photograph (through a microscope) of a board with its stencil offset slightly right and up.
I needed to slide it a little off-center because it's so perfect that it disappears when placed in the
correct position!
Sizes: the resistors are 0805, the capacitors are 0603, the 5-pin IC in the lower left is
SC-70-5. I was able to export DXF from EAGLE, the PCB design software that I use (I've also got a page with tips for using EAGLE), and import into Silhouette Studio, but this step is tricky. The default DXF export from EAGLE uses "blocks," which aren't understood by Silhouette Studio. The best solution I've found was suggested by Junichi Nagayama, who told me about this custom DXF exporter that creates DXF files for the top and bottom "cream" layers. In addition to creating DXF that Silhouette Studio understands, it's very convenient since it automatically uses the tCream and bCream layers; there's no need to turn other layers off before exporting. (My original solution was to use a CAD program to convert the blocks to "polylines." Those steps are archived on a separate page in case my new solution doesn't work for everyone.) Exporting from EAGLEOne-time setup step: Copy cream-dxf.ulp to your EAGLE ulp folder. To export DXF files for top and bottom surface-mount pads (cream layers):
This will generate filename-tcream.dxf and filename-bcream.dxf files in the folder containing your filename.brd file. One note about DXF: It appears that it does not encode an indication of units. This DXF exporter uses millimeters, which is what Silhouette Studio assumes. Importing into Silhouette Studio and CuttingOne-time setup steps: There are two settings you'll need to make once; both are in the Preferences dialog that you can find on the File menu (Windows) or Silhouette Studio menu (Mac):
Each time you want to cut a stencil, do the following steps:
Now you're ready to use the stencil to apply solder paste, add components, and heat it on a griddle. ThanksI want to acknowledge several people who have shared their ideas and helped me improve the information on this page:
