Thanks for all of the replies!
First of all I have a Laser Point 24" cutter. I misplaced this thread, sorry.
I am at this moment still having troubles. I did NOT have the blade offset to .25 and I may have never set it before...not sure. I have cut quite a bit of vinyl since I bought the cutter with great results using the original blades that came with the cutter. I changed the blades as I felt they were getting dull, but I am new and could have thrown away good blades. I feel I have learned to adjust the blade and set the pressure pretty well, but I have been playing with it for a few nights now and am getting various results depending on what I cut. Pressure set between 119-130 and blade just barely sticking out and I will get a few good cuts on larger items but it gets bad on anything with detail, chattering and not smooth, straight lines. I am pretty sure when I had the blades that came with the cutter I was using about 121 pressure. All vinly has been Oracal 651.
Thanks again for all the helpful suggestions! I am hoping some 45 degree blades will get me back on track.
