Perform Test Cuts on New Cutter

You have received your new cutter, made a place for it on your desk, and now you need to test your new cutter to get started using it. If you need help setting up your cutter, see  this document called Get Your Cutter Out Of The Box. I know you might be afraid of hurting your machine, but you don’t have to worry about that if you follow the steps provided here on how to do some test cuts. If your machine has issues, now would be the best time to discover them, while it is still under warranty, and you still have all the packing materials handy should you need to send it back to your place of purchase. I will walk you through the tests that I perform on each of my new machines as I get to know their capabilities and become familiar with what they can and cannot do. Your tests will reveal cutter accuracy, maximum cutting width, where it cuts, where cuts start, what media it cuts, and what settings work best for the types of projects you want to make.

Loading Your Mat

Before you can make some test  cuts on your new cutter, you will need to load your mat into the cutter. Cutting machines designed for crafters usually include a cutting mat. The exception would be if you are cutting vinyl with a backing. Dedicated vinyl cutting machines do not require a cutting mat, because vinyl has a protective adhesive backing, through which the blade should not penetrate. Vinyl on a roll may be fed through this type of cutting machine without using a cutting mat. Multi-purpose cutters such as Pazzles, Cricut, Scan N Cut, Silhouette, KNK, and Silver Bullet are shipped with cutting mats that allow crafters to not only cut vinyl, but also to cut other media that does not have a protective backing.

This Side Up

The cutting mats have adhesive on them to keep the media in place as cutting progresses. The adhesive is protected with a cover that should be removed before using. Before removing the cover, mark the top side of the cover with the words “This Side Up”, as sometimes the covers are different on each side. After cutting, scrape the mat clean, wipe down the mat with non-alcohol wipes, and replace the protective cover with the correct side up. Store the covered mats flat so that they do not become warped.

Some machines such as Silhouette, KNK, and Silver Bullet allow users to cut vinyl without a mat, or to use a mat for other types of media. Other machines such as Pazzles, Cricut, and Scan N Cut require users to always use cutting mats. These machines have an auto-load mat feature. To load the mats into these cutters, simply press the edge of the mat firmly against the rollers, and press the Load button. The mat will feed into the machine automatically, and position the cutting head at the proper start position.

Test Using A Pen

Cutting mats vary greatly in thickness, stiffness, and weight. It is possible for an incorrectly set machine to cut all the way through a cutting mat, and thus ruining both the mat and blade. For this reason it is important to do test cuts on your cutter. Your first tests may be done using a pen in the carriage instead of a blade. You can use paper on the mat for doing these tests. Use an inexpensive piece of 12″x 12″ paper or card stock on the mat for the initial tests. Because the adhesive on new mats can be quite strong, card stock may be easier to remove  from the sticky mat than light weight paper. Align the corners of the paper on the grid lines printed on the mat, and press the paper firmly in position. Check your pen to make sure it writes by hand. Place the pen in the carriage according to the Quick Start instructions provided with the machine. Load the mat into the machine. Some machines require an optional pen holder for using pens.

The first test cut is to find out the cutting boundaries of the machine. The cutting mat is marked to hold a 12″x12″ piece of paper, but some machines cannot cut the full 12″ width. The manual for your cutter should indicate the maximum cutting width for your machine. Open the software designed to work with your cutter.

Add a square from the basic shapes in your software and resize it to 12″ square. Line up the upper left corner of the square on the screen to x=0 and y=0. Set the software to draw. Send the file to cut. If there are presets for drawing pressure, use the default setting. If your cutter will draw a full 12″ square, notice where the square was drawn. Did it draw directly on the edges of the 12″ square paper? Did it draw any of the lines way off of the paper? Where did the drawing start – upper right or upper left? Lower right or lower left? Measure the drawn lines. Did the height of the square measure the same as the width of the square?

If your machine will not test cut a full 12″ width, you will receive an error message. Resize your square to 11.5″, and send it to the cutting window. If there are presets for drawing pressure, use the default settings. If the square is drawn on the paper, check to see where the square was drawn. Did it draw where you expected it to be drawn? Where did the drawing start? Measure the drawn lines. Did the height of the square measure the same as the width of the square?

How accurate are your test cuts ?

Resize your square to 10″. Send it to draw. Measure each of the sides of the square that were drawn. Are  all sides  exactly the same measurements? Measure with a metric ruler. If your measurements are off even 1 mm, you will get lopsided circles, scallops, squares, and cards and frames won’t be perfectly square. If you want to cut around printed images precisely,  you will need accurate cutting.

Are there options in your software or on your machine to fix this problem? Are perfect cuts important to you? Every machine is mechanically different. I may get perfect test cuts on my machine, but your machine of the same brand may not have the same results. Contact support for the company from which you made your purchase for help in making adjustments for these mechanical differences. One company that I contacted provided instructions for adjusting the step size to fix the inaccurate cutting. Another company told me that if I needed perfect cuts, that I should probably send the machine back for a refund, and purchase a more professional machine.

Where will cuts be made?

Now, resize your square to 1″, and duplicate it so that you have four 1″ squares. Place the upper left corner of one of the squares at x=1″ and y=1″ . Place another at x=10 and y=1, another at x=1 and y=10, and the last at  x=10 and y=10. Send it to draw. Did the squares all draw at the precise locations on the cutting mat where they  appeared on the screen? It is possible that one of the squares drew in the correct place, but perhaps ones that were further away from the starting point were not drawn as close to their screen positions. Make note of your test results .

Test Cuts

One Inch Squares Test

It is important to note how far off the shapes were drawn. You will frequently need to cut scraps. Knowing where to place the design pieces on the screen in the software to correspond with the location of the scraps on the cutting mat can help you maximize the accuracy of your cuts. If a design calls for six or eight small pieces of different colored papers, you may be able to position pieces of each of the colored papers on the mat in specific locations to have all of the pieces cut in a single pass.

If your 1″ squares all drew within 1/2 inch on the mat from where they appeared on the screen, allowing an extra inch  in height and width of paper  for each design piece to cut on a scrap should be sufficient. For example, if you want to cut a 2″ flower from a scrap of yellow paper, you may need to use a 3″x 3″ piece of yellow paper on the mat to have a little extra room  to get the flower cut out completely. But if your squares all drew precisely on the mat where they appeared on the screen, you may be able to use a scrap just slightly larger than 2″. It helps to have an idea in advance of how much variance there is between screen and mat locations.

Test Cuts With a Blade

For optimal cutting with the least waste of media, and the least wear and tear on blades and mats, small test cuts should be made prior to cutting each project. Some software has built in test cuts, and some machines have built in test cut functions. You can make your own small test cut file to use and add it to your projects before sending them to cut. I like to use a small, five-pointed star inside of a small square. I resize the square to about 1/2″, grouping it together with the star. This small cut can be added to a tiny bit of unused space on every project. It is easiest to check your test cuts if you place them somewhere near the bottom of the mat rather than near the top where they will be difficult to check without unloading the mat or moving the carriage.

Test Cuts

Start with a bit less than the recommended blade extension, speed, and cutting pressure or “force” for your first test cuts. Your goal will be to use the least amount of blade extending from the blade housing, and the least amount of pressure necessary to make good clean cuts through the media you are using for your project. Too much blade, or too much pressure will cause media to bunch and tear. Too little blade or not enough pressure will result in parts of the design not cutting through the media.

After doing your test cut with the tiny star in a box, check the points of the star. Does the star lift out of the box easily and cleanly? Are the points of the star bunched or smooth? Is the box cut cleanly so that it lifts out of its position? Did the cut leave a small attached tag between the start and end of the cut? Did the cut leave a gouge in the cutting mat? If both pieces of the test cut do not lift out easily, then move the test shape, make adjustments in blade or pressure, reduce the speed, and try again.

It is normal for the blade to leave a slight scratch on the surface of the mat, but it should not cut deeply into the mat. Retract the blade in its holder if it has cut too deeply into the mat. Slower speeds produce more accurate cuts. Repeat the test cuts multiple times, each time making a small adjustment. Once you have found a blade depth that cuts cleanly through your media, you can make additional adjustments in the pressure, up or down as necessary.

Record the Results of your Test Cuts

Use a chart to record the best settings you used for each media type. Refer to your chart to determine the best settings to start with the next time you need to cut a similar media type. Get a free copy of the Personal Media Settings Chart  from the Free Library.

Doing test cuts can save you lots of time, money, and frustration. Recording the results of your test cuts will save you time for future reference. Environment, changes of media type or color, blade condition, and mat condition can all effect the quality of your cuts. Make test cuts and necessary adjustments frequently to avoid damaging your blades, mats, and media.
