Well it almost seems that the blade doesnt turn properly. As we cut simple designs, it will cut straight fine, but then it will encounter a somewhat sharp edge, and drag, causing the vinyl to tear and get bunched up. Not all the time though. We have cleaned and lubed the blade bearing and in our hand it seems to work fine. It also tends to shift the vinyl so that the design is all f%#$ed up. Instead of a nice straight logo, it ends up being a warped mess. Got any ideas before I chuck this thing out the window?
If you have replaced and oiled the blade, I am at a loss. I have an old Ioline Classic 24. Check that the blade is well seated in the holder. Have you called Ioline? They are great with their Tech Support.
I had the same problem. It was the wrong blade. Also, the knife blade might be adjusted incorrectly. You are supposed to turn the holder until no blade is exposed, turn the pressure knob so that it is 2 notches from the highest pressure setting and test cut until it just cuts the vinyl. Check the blade you are using. Is it notched or does it look chunky and thick? My vinyl supplier was only recieving the thick one from their supplier, so that's all they were carrying. It butchered my vinyl on anything under 1/2". It is designed for thicker material. The top picture is the correct blade for cast and calendered vinyl. The catalog is from Grimco 1-800-760-5575
I sure am glad you posted a pic of those blades. I just got a used 40" super 88 and when I did a test cut it bunched up the corners. It has the blade for the thick material in it. I was getting ready to order another one that looked just like it.
