brunelloinc posted a topic in GraphTec Cutting Plotter Support RequestsHello, Sorry for the long post. Just trying to give as much info as possible up front to minimize any followup questions. Summary: I'm new to the forum and this is my first experience with a vinyl cutter. I'm having issues cutting small circles consistently and would love some help and suggestions for tuning the equipment and settings to get the best possible cuts. Background: I purchased a new Graphtec CE6000-40 and I'm cutting using Adobe Illustrator and Cutting Master 3 software/plugin. I'm cutting Oracal 951 vinyl. Attempting to cut small circles, 5mm in diameter. The circles are set up in groups of 3, spaced about .5" apart. The issue I'm having is that the third circle in each set is showing what I would call a blade mark, or what others have described as a "hangnail" or in complete circle. For whatever reason, this is ONLY happening on the third circle in the set. The first one is fine, the second is slightly worse, and the third is unusable. What's also interesting is that the problem gets progressively worse on the right side of the sheet vs. the left. In other words, the third circle in each set is the worst, but the third circles on the right of the sheet are worse than the third circles on the left of the sheet. I watched the movement of the blade and the third circle is the last circle it cuts in the sequence before it moves to the next tile. It's almost as if the machine is "rushing at the end" to move to the next tile and that's why it's imperfect. (Although I know that's probably not really what's happening.) It may seem minor or that I'm being too picky, but the fact that the first circle is perfect leads me to believe that they can ALL be perfect. I'm viewing the circles under a loupe, and also under a 10X macro lens. That said, the issue is still visible to the naked eye upon close inspection. I've read a lot of info on the forums here and I think I have my blade height set correctly. I've also experimented with various speeds and levels of force. I checked the file - it's nice and clean. It's just a simple circle drawn in Adobe Illustrator. There are only 4 nodes on the circle. I've attached some macro shots to show the issue, along with the EPS file that I'm cutting from. Details: Here's are the details of my equipment and settings: Graphtec CE6000-40 Cutter Blade: Graphtec CB09U-K60 (60º, 0.9mm) Condition: Blade: Graphtec CB09U-K60 (60º, 0.9mm) Offset: 0 Speed: 1 cm/s Acceleration: 0 Cut Force: 10 Passes: 1 Tangential Mode: Off Tool Setting: Step Pass: 0 Offset Force: 2 Offset Angle: 0 Initial Blade Position: 2mm Below When Tool is Up: Speed: Auto Advanced: Move Step: 0.1mm Step Size: 0.010mm -------- Any help or advice you can provide would be greatly appreciated. Thanks in advance. small-circles.eps
