312.09 Important Checklist Before You Cut! Do you have your material on the mat and the mat inserted into the cutter? (Note: materials with a backingsheet, such as vinyl and iron-on transfer do not require a mat for cutting) Do you have the mat under the pinch rollers and the levers lowered in the back? Have you set the blade length/exposure based on the thickness of the material you are cutting? Do you have the blade holder firmly mounted in the blade holder seat and the blade tip at the correct heightabove the material? Have you set the origin at the front right corner of your material (or where you need the origin to be)? Have you set the force? And the velocity? Have you selected the correct Offset value for the blade you are using? Do you need to turn on Multi-cut for this material? Do you know, with confidence, where your shapes are going to cut?2.10 Calibrating the ACS-24UHF Resolution Digital die cutters may cut shapes slightly off from the size of the shape in the software. For example, an 8”x 8” square might cut 7-15/16” x 8-1/32”. Now this might be perfectly acceptable for the type of cutting youdo. Therefore, it may not even be necessary to do this particular calibration. However, if you do want tomake sure your shapes are cut precisely, the following procedure will allow you to calibrate your ACS-24UHF. Note that this Resolution only applies to Knife Point and WYSIWYG cutting modes. For Print and Cutapplications, Resolution is determined automatically based on where the registration marks are set with thelaser light during the print and cut process. Go to File>Import>From Basic Shapes and select the category called Polygons. Then scroll down tolocate the Square and double click to place the square onto the screen: To resize the square, select it and then at the top right of the screen, change the W to, for example, 8inches. Note that the larger the shape, the more accurate your calibration will be. If you prefer to enter a sizein mm, then enter 200 mm, but enter it just that way, with the “mm” following the 200. The value will beconverted to inches, but not to worry: you can still perform the calibration in mm.A square willappear on thescreenSelect PolygonsDouble click onSquare to add to thescreen.
