@Dakotagrafx I sincerely appreciate you helping at all. Unfortunately, "don't adjust the pinch rollers in the first place" is about the only advice I can find anywhere on the internet in regards to adjusting them and it doesn't do much after they've already been adjusted. You say it's a fine line. Do you have any expertise beyond that? What am I supposed to be looking for? If a roller is tighter than another will that push the vinyl or will one that's too loose push the vinyl? What metric is used to set them from the factory?

I understand that but your comment is not helpful. I attached a photo of the pinch rollers' current settings to my post above. I've attached a photo of the vinyl after cutting using those settings. Do I need to tighten the pinch rollers more?

I did adjust the pinch rollers. I backed them all the way out, marked the thumb nuts, then adjusted them all the same number of turns. The nut is about halfway down on the screw and I am getting roller marks. It's not as defined as they were on Oracal 751/951 where the texture of the roller was really evident but I figured that was because the Avery SW900 is thicker and already has its own texture.

I'm sure the blade depth is correct. I cut a few sample pieces and there was no marking on the backing at all. Granted, I'm using SW900 so the backing is textured but there is no noticeable marking, once the vinyl has been removed. So 144" is more a function of memory than ability to accurately track? That seems misleading. If I wanted to cut out a single line that was 288", I'm sure the machine would have the memory for it but if it can't keep the line straight past 60" then what's the point? The most frustrating thing, for me, is how the machine was accurate up until the end. Is there a way for me to reverse the order of cuts so the large pieces are done first? That way, if it screws up, It's not wasting time cutting out the inside of the logo, and I can at least save that uncut portion inside to use for smaller cuts.

I have a 28" SC2. I'm trying to cut a large logo for a vehicle graphic. It is 6.5' x 1.5' and I'm using Avery Dennison SW900. I've wasted a lot of Oracal 951 already, practicing cutting this logo, due to shift. Today, I tried on the SW900 material and got so close to perfection but the last two to three cuts, the vinyl shifted. Can anyone offer me some insight? This machine is advertised as being able to cut up to 144", right? I've attached our logo file for reference. I'm using the free vinylmaster software on a windows 10 PC. Here's my method after much trial and error. I pre cut the length of vinyl so it is not feeding from the entire roll I used masking tape on the machine to note the edge of the vinyl I have two plastic folding tables set up on either side of the cutting mechanism to hold the material When the material exits the machine, I fold it over itself to reduce the amount of material being moved in half. While working, the vinyl sheet resembles a belt. Noting my file, the cutter successfully cut the letters in the center, then it started cutting the ovals starting from the inside out. After about two or three ovals, there was a slight shift, maybe 1 mm. Nothing that would be noticeable. Before cutting the last oval, it cut the weed line which is the rectangle surrounding the entire design, added by the software, itself. (not part of my design). From here, I noticed a significant shift. Then it cut the last oval and it started to overlap some other parts of the design so I had to pause the machine and give up the cut. It was probably 1/2" or more off from the masking tape. The only thing I can think of is my pinch rollers need adjustment. I can run the material through without cutting and during the cut, the material is fine, with minimal shift. Not sure where the issue occurs. The screws on my pinch rollers are about in the middle of the thumb nut. I marked them and turned them all the same amount of times starting from the top of the screw flush with the nut. *trademarked vector deleted per forum rules***
