− | # Setting up a Job | + | # '''Setting up a Job''' |
− | ## First off, to get your design, just copy an image and paste it into Inkscape or find a pdf version of the file and open it. If you are cutting a part from a Solidworks file it must be saved as a dxf before importing to Inkscape. | + | ## First off, open a new document in Inkscape on your own machine or one of the lab computers (File > New, or Ctrl + N). Next, you’ll want to set the dimensions of your page by going to [File] > [Document Properties] (Ctrl + Shift + D). Your page can be as big as you like, as long as it’s larger than the shape you’re working with. However, always '''make sure that the document is square.''' There’s some weird quirk with the software that makes this necessary, keeping the document square will keep you from running into a lot of problems later on. Under the “Custom Size” section in document properties, set your hight and width to something larger than the longest dimension of your object. When you export the shape to the laser cutter, Inkscape will export anything within the document canvas and ignore anything that extends beyond it’s borders. |
− | ## To open a dxf file go to [File] > [Import]. If a dxf file is being used feel free to skip to step 7.
| + | ## Now you’re ready to create a shape to be cut or engraved. a.) If you’re importing a shape from SolidWorks, the file should be saved as a .DXF file. Simply drag the file onto your Inkscape document or import it via [File] > [Import] (Ctrl + I). If prompted to select scaling options, choose “read from file” and click OK. Next, select the object and go to [Object] > [Ungroup] (Ctrl + Shift + G). This will allow you to select the text objects that make up the SolidWorks watermark and delete them. While you’re here, make sure that there is only one copy of each line, as SolidWorks often likes to make duplicates. Finally, you may want to select all of the remaining objects and regroup them with [Object] > [Group] (Ctrl + G). Skip to step 5. b.) If you want to cut or engrave from an image, the best way to do so is from a vector image file. Vector graphics files store the lines, shapes, and colors that make up an image rather than storing data based on pixels as in a typical raster image. These lines, shapes, and colors is what the laser cutter interprets when cutting and engraving. If you’ve designed something in Adobe Illustrator, Inkscape, or other vector-based drawing applications, you can save your image directly to this format. If you’re looking for images online, search for vector images. These will most commonly be in the format of .SVG, .EPS, and some types of .PDF. You can import these types of images into your Inkscape document by simply dragging them onto the canvas or importing them via [File] > [Import] (Ctrl + I). Skip to step 5. c.) If you want to engrave or cut a raster (pixel-based) image, you will need to convert it to a vector shape. Drag your image onto the Inkscape canvas and proceed to step 3. [[File:...gfuLogo.png|none|thumb|600x600px]] |
− | ## Measure the size of your material, and set the page in Inkscape to those dimensions. You can alter the dimensions of the page you are putting the image on by selecting [File] > [Document Properties], and even the width (W) and height (H) image itself in the top. If you want to keep the image dimensions consistent, but just scale it down, click the lock button between these dimensions. If you want to make your own design using text, squares, circles, etc, you can find everything you need in the column on the far left of the client.[[File:...gfuLogo.png|none|thumb|600x600px]]
| + | ## Inkscape can convert an image into vectors based on the composition of the source image. To do this, select your image, right click, and select Trace Bitmap, (Alt + Shift + B). You will be given several options shown below. Check the “Live Preview” box which will give you a better idea what’s going to happen. For the George Fox logo, we want to separate the colors from each other, so we’ll select “Colors” under the “Multiple Scans” section. The number of scans you specify correlates to the number of objects that Inkscape will create based on the different parts of the image. Since our example is a simple logo with 3 colors, 3 scans will be sufficient. Depending on your image, you’ll have to play around with these settings a bit. For a back and white image, you’ll probably want to use “Brightness Cuttoff” under “Single Scan” and adjust the “Threshold” value until the preview looks correct. Once you click OK, the vector will appear directly on top of the original image, so make sure to drag it off and move or delete the original image. [[File:...traceBitmap.png|none|thumb|600x600px]] |
− | ## Once you have your design, we need to alter the colors a little bit so the Laser Cutter can understand what you want it to do. It goes like this: a red stroke will cut, and anything that is black will engrave. A stroke is merely an option that outlines the object you select. | + | ## You will now have a vector object that consists of several parts. Separate them by right-clicking the vector and selecting “Ungroup” (Ctrl + Shift + G). Now you’ll be able to alter each part of the object. In our example, we’ll go with the one on the right and delete the one on the left. [[File:...separateParts.png|none|thumb|600x600px]] |
− | ##In order to do this, we need to split up the image into different pieces. This is called vectoring, where it will divide the image into different pieces based on shapes and color. Just select the logo, right click, and select Trace Bitmap. You will be given options shown in the picture below. For this application,we want to separate the colors from each other, so we select the Colors option. The number of scans you have selected will define how closely the vector output will replicate the actual photo (the bitmap) or how many colors you want the vector to tape. Since this is a simple logo and we have 3 colors/shades to take, 3 scans will be enough. If the detail is not good enough, try the other options and have some fun. Once this process is finished, the vector will appear directly on top of the original image, so make sure to drag it off and separate the two before beginning.[[File:...traceBitmap.png|none|thumb|600x600px]]
| + | ## Now we can manipulate the colors. Select the object and go to [Object] > [Fill and Stroke] (usually it will already be open on the right sidebar). You will see Fill, Stroke Paint, and Stroke Style on the top right. Fill changes the color of a piece, Stroke Paint changes the color of a stroke, and Stroke Style changes the thickness and style of a stroke. You will see values for R, G, and B, which control color. When each color has a 0 next to it, it will be fully black. When the red has a 255 next to it and the others have 0, it will be fully red. The machine will cut material ONLY when it sees a stroke that is 255, 0, 0, and it will engrave material ONLY when it sees 0, 0, 0. Set these values on your object depending on what you want to engrave or cut, and make sure these values are exact before continuing. Anything that you do not want to cut or engrave, either delete or set to white, which is 255, 255, 255. Be sure to make each a “Flat Color” so that the color is constant throughout the entire object. |
− | ## Since there are a few separate parts to this vector, it is possible to break apart these and alter the image however you want. Select the image, right click and go to Ungroup. Now you can mess with each individual part! You can take either of these designs and delete them, essentially they will cut out and engrave the same design. Let's go with the one on the right. [[File:...separateParts.png|none|thumb|600x600px]] | + | ## Now that you have an object with the correct fill and stroke, you’ll want to resize it to the size you want. Select your object, and in the top bar of Inkscape you’ll see options for height and width. If you want to scale the object without altering it’s height and width ratios, lock the two together by clicking the lock icon. Measure your material and set the height and width accordingly, or set the values to your desired size. If you imported your file from SolidWorks you shouldn’t need to change these dimensions, just verify that they match the size of your object in SolidWorks. [[File:...Stroke.png|none|thumb|600x600px]] |
− | ## Now we can manipulate the colors. Select the object and go to [Object] > [Fill and Stroke] (usually it will already be open on the right sidebar). You will see Fill, Stroke Paint, and Stroke Style on the top right. Fill changes the color of a piece, Stroke Paint changes the color of a stroke, and Stroke Style changes the thickness and style of a stroke. You will see values for R, G, and B, where all colors can be made using these. When each color has a 0 next to it, it will be fully black. When the red has a 255 next to it and the others have 0, it will be fully red. Make sure you check these bit values before continuing, since the machine is set to cutting material ONLY when it sees 255, 0, 0, and it will engrave material ONLY when it sees 0, 0, 0. Everything else, make it white, which is 255, 255, 255. Be sure to make each a Flat Color so that the color is constant throughout the entire object.[[File:...Stroke.png|none|thumb|600x600px]] | + | ## Once you have finished your design, it’s time to send it to the Laser Cutter! Go to [File] > [Print] (Ctrl + P) and make sure it is sending to Trotec Engraver but do not click [OK] yet. |
− | ## Once you have finished your design, it’s time to send it to the Laser Cutter! Hit print, make sure it is sending to Trotec Engraver but do not click [OK] yet. | + | ## Select [Preferences] to open the engraver properties. Check both “Take From Application” and “Minimize to Jobsize.” These settings tell the program to assume the canvas is the same size as it is in Inkscape and then crop to the size of your print. Also verify “Image Mode” is set to “Color” and “Enhanced Geometries” is not selected. '''NOTE''': “Take From Application” will only work if your Inkscape canvas is square. Make sure to set this correctly, or else set the print size to something larger than either dimension of your print (so long as “Minimize to Jobsize” is enabled.)[[File:...printing.png|none|thumb|600x600px]] |
− | ## Select [Preferences] to open the engraver properties. You will want to make sure the [Minimize to Job size] option is NOT selected and that the [Height] - [Width] values match the page size selected in Inkscape. DO NOT have [Enhanced Geometries} selected because it causes the curved parts of your design to be unrecognized once it is uploaded to the Job Control.[[File:...printing.png|none|thumb|600x600px]] | + | ## Save these settings by selecting the button that shows the JC logo near the bottom of the Printing Preferences and select Print to send the design to Job Control. |

| + | ## Turn on the machine using the power switch located on the back of the machine in the left corner. The machine will go through a startup procedure where the cutting bed lowers and the laser travels to its home position. Note that the lid must be closed for the startup procedure to begin. You will hear be some beeping coming from the machine. |
− | # Setting up the Laser Cutter | + | ## Place your material onto the honeycomb table. '''ALWAYS''' place it in a corner, snug against two sides of the bed. This way if something doesn't go quite perfectly in the cutting process you can return the material back to that corner and try again without having to scrap the entire piece. |

The machine will go through a startup procedure where the cutting bed lowers and the laser travels to its home position. Note that the lid must be closed for the startup procedure to begin and there will be some beeping coming from the machine which is normal. | + | ## Now it’s time to focus the laser onto your material. Begin by moving the laser head over the middle of your material. Place the focusing tool on the laser head and slowly raise the table until the the focusing tool just barely touches the material. Be sure to raise the bed extra slowly when approaching the focusing tool, so that you can stop the moment you are at the correct height. Use cation, as there is also no safety in place to prevent the material from crashing into the head and damaging this delicate, expensive assembly. The focusing tool will likely fall off the head; this is fine so long as you didn’t overshoot the point at which it first touched. Reference the images below for proper focusing tool placement and laser head controls.[[File:Laser Focus Tool.png|none|thumb|404x404px| Proper placement of the focusing tool. ]][[File:Laser Controls.png|none|thumb|296x296px| Laser control pad.
