MCobb 0 Posted August 15, 2018 I've been using the FC8000-60 for a few months now and I've had issues on and off at the beginning, but then I was able to sort through it and have it running well for the vast majority of the time. Eventually, the blade was getting too dull and I put a new one on. Immediately, it wasn't pressing into my laminated vinyl as much as the original blade was. If I turn up the pressure to ensure it cuts deep enough, I seem to start having issues where the alignment around corners won't line up right. At a corner, it will occasionally turn funny. I've attached a preview of the offset test, and it's really hard to see on screen so I traced it really quick and moved the trace above the actual photo so you can see what I mean. Those are supposed to be perfect squares, but they aren't. I've tried changing the offset, no setting works. I've tried changing how far out the blade tip goes, nothing seems to be working (if it's too far in, it doesn't pierce the laminate. if it's too far out, misshapes like this get even worse. But there's no happy medium where it actually cuts correctly). The blade is a CB15UA-K30-2, which is the same as the previous one. (In case the tip was damaged, I tried replacing it with a third blade, but the issue persists). We actually had a different blade in at the start, CB09U I think, but we were having the same issues as I am now, which is why we changed and which seemed to fix it. My current settings are: Offset: 2 (gone through many changes though) Speed: 15 (we usually run closer to 25 though, as I'm in a business that makes many labels. Was fine for several months at 25) Acceleration: 1 (I believe I was at 3 before. Again, just trying to slow things down to improve the cut but it isn't working) Cut Force: 29 (definitely higher than I want to be, but I can't get it to cut otherwise) Tangential Mode: 2 Start Ext / End Ext 0.3mm Init Force 3 Tool Setting: Step Pass 1 Offset Force 2 Offset Angle 18 Anyone have any advice?

MZ SKEETER 4,709 Posted August 15, 2018 I don't know how you set your blade depth, but this is the correct way below and it works. Also blade offset on a Graphtec is 0 ZERO I never cut with a speed that high. That's just me. Instead of cutting in 1 pass, try cutting 2 passes. To start with, you should set your blade depth correctly, by taking the blade holder out of the machine, and firmly cut across a piece of scrap vinyl, you will be cutting. You should only be cutting the vinyl and barely a mark on wax paper backing, Adjust blade to get there, Then put the blade holder back in machine, and use the force of the machine to get there, same results, only cutting the vinyl and barely a mark in wax paper backing. You should just barely see and feel the blade tip out of the blade holder. Share this post Link to post Share on other sites
MCobb 0 Posted August 15, 2018 Okay, I followed those steps to get the blade to poke out as little as possible while still cutting vinyl and not backing, and changed the offset to 0. At 1 Pass, the blade only cuts deep enough if set to 28. At 2 Passes, it still needs to be around 24. With either force setting, the same issues with corners persists. With two passes it's less noticeable because sometimes it will cut bad on one of the passes but not the other pass, but in the end that still leaves for a weird cut. Do you know if there are any other settings that might be interfering as well? Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted August 15, 2018 You don't state which cutting software you are using, but are you making sure that the settings are the same in the cutting software as well as on the machine? I personally use the Graphtec Cutting Controller( download from Graphtec site) and change all of my settings from my computer... My computer controls all of my settings, Force, speed, offset etc. Share this post Link to post Share on other sites
MCobb 0 Posted August 15, 2018 I'm using Cutting Master 3. I typically change the settings from my computer. I'm using files from Adobe Illustrator and Cutting Master 3 seemed to be the program best suited for that. Should I try Graphtec Cutting Controller? The reason I didn't mention the software before is because even if I just do the test cut right from the FC8000-60, it still happens, and that isn't software-specific so I assume the issue isn't in the software itself.

MZ SKEETER 4,709 Posted August 15, 2018 No, the software is not doing that Test for the offset like that. Until you get that TEST correct, you will have problems. What does the test look like with the pen? Use regular vinyl and not laminated. Have you checked your cutting strip for gouges, scratches etc. ? Share this post Link to post Share on other sites
MCobb 0 Posted August 15, 2018 I don't have the fiber tip pen. I don't think I can test with just any old pen, can I? Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted August 15, 2018 No. but keep doing some offset texts on regular vinyl I don't think my pen was fiber tip. Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted August 15, 2018 Have you cleaned out your blade holder? Add a drop of thin oil? Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted August 15, 2018 Just looking at my cutter settings, in my menu and I have the Graphtec FC7000-MK2-75 and it cuts perfect. I have never changed those settings since I got the cutter new in 2008.. My offset angle is 30... offset force 7 I don't mess with tangential mode. In your background settings. Condition Priority> Mine has Manual or Program, I have mine set to Program, as I am running from my Graphtec cutting controller and not from my actual cutter settings buttons. When I use the Graphtec Cutting Controller from my computer, it creates Condition 9 on your cutter screen. It is a Windows program. Your Graphtec cutting controller may be different. My cutter is a FC7000-MK2 Share this post Link to post Share on other sites
MCobb 0 Posted August 15, 2018 I added a drop of thin oil, I turned off tangential mode, and I increased my offset force+angle (I originally turned the force down because it was leaving a cut within the cut area. But there's a setting telling it to start 2mm below the start area versus outside the cut area completely, so I changed that to outside and that seems fine). And it seems to be better now. I can't tell yet if it's completely as it should be, but I think it's good and you can assume the issue is resolved unless I post again to say otherwise. I don't really know about the condition priority or the 9th condition, but hopefully I don't need to? Fingers crossed. Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted August 15, 2018 Condition priority is in your menu. Under Background settings. (Mine is) Condition 9 comes up only when you use the Graphtec Cutting controller. What do your test cuts look like now? Yes, you want that little J on the outside of the cut. Share this post Link to post Share on other sites
