Thanks, I'll try those things in the morning. The blade depth right now is set so low that there is zero marking on the backing liner--any less blade and it starts to get hard to weed. I have a couple new Clean Cut blades that will be here tomorrow so I'll just use that as a good chance to reset the whole blade setting process and apply a little of the 3 in 1 oil. The pressure on the rollers was in response to someone asking me to check them while under pressure--as in when I spun them I pressed on the roller very hard with my fingers. The pressure of the roller when cutting is actually very low and it holds very well with the tape. The liner of the Xpel PPF is a poly liner, so I think it may help it hold better than a paper liner would with the mentioned tape over the high grit rollers. Thanks for the replies guys!!

Didn't even think about that, but rollers do spin freely with high load. It seems as though this is a common problem among plotters--having the blade be turned the wrong way when it's inserted in to the material. Some of my larger size jobs hide the blemish because it's such a big piece but other jobs require the small piece to be perfect. I did see a suggestion on a Graphtec forum to have the blade make a small straight line cut next to the piece to help align the blade before it's plunged in to the material. I might give that a shot.

No, it doesn't fill the cutting area. I also make multiple pieces at a time so moving the rollers around all the time wouldn't be feasible.

I'll have to look at that more closely in the morning but I do know that I keep the roller over the grit part. I actually added a layer of electrical tape over the grit roller to eliminate roller marks in the material. It actually works great and holds the material very well. The tape eliminates the harshness of the metal grit. The bunching was happening before I made this change too, even with the roller pressure cranked up to full.

I emailed Clean Cut and they do NOT suggest using the thinned 60*. I ordered a regular 60* so we'll give that a shot. I think 1-2 additional pinch rollers would help hold the material in place too--just wish they weren't so dang expensive, and I feel like this is just a bandage that should be able to be fixed another way.

Thanks for the suggestions. I'll pick up some 3 in 1 oil tomorrow--I think that will really help. I'll poke around in the SB setup again. I really wish there was a way for me to click on the exact starting spot though. As far as the plotter--the Graphtec just aint gonna happen, regardless of how perfect it would be for PPF. I know the SC isn't ideal but it's what I have to work with.

No, I wasn't interested in trying that blade until someone with prior experience had done so. I emailed cleancut last night for suggestions.

Is there any way to adjust where on my object the blade starts its cut? For instance, I cut out small odd and somewhat rounded shapes and about 1/4 of my shapes are scrapped due to the blade being in the wrong orientation when it's initially plunged in to the shape to cut. Some cuts are fine as the blade was already turned in the right direction and it doesn't make that small sideways or angled slash as it's first set in the material. The problem is this blemish is always in the worst absolute spot on the shape and could likely be unnoticed if it could be located right on a corner or other specific spot. Is there any way for me to specify the point where the cutter sticks the blade in? If SB doesn't allow this is there another software that does? Or any other suggestions to fix this? Thanks a ton!

Hey guys and gals... just wanted to move this one back to the top. I haven't had any luck with the bunching. I've tried taking the blade in until it stops cutting all the way through the material and it's still bunching. I've also increased and decreased pressure with no luck. Spraying on WD-40 did nothing for me either. I've inspected the blade tip and it looks perfectly fine. I've also tried replacing the blade with a spare and brand new 45* and get the same exact tugging. What OTHER things can I try or check? This is getting to be a huge PITA as it's distorting the material as it cuts and doesn't allow the blade to meet back up with its exact starting point, forcing me to scrap about half of my production. On a side note, the roller marks has been completely solved with some electrical tape. Just wrap one layer of electrical tape around the roller and bam, all roller marks gone and zero slippage. The back of the PPF material grips the tape and soft rubber pinch roller very well.

Has anyone tried the clean cut blade 60* thinned? Might be great with PPF. http://store-a5fbf.mybigcommerce.com/products/Roland-60%C2%B0-Thinned.html

Thank you for the reply. I thought that might be the case at first too, but the problem persists with high or low roller tension. It sure looks like it has to do more with the material not having enough horizontal stiffness to hold its shape. It kinda buldges up as the blade moves through it.

Cutter: SC Series Blade: 60 degree blade supplied with cutter, only used on a couple yards of material Software: Signblazer Material: XPEL Ultimate PPF (poly liner) I tried searching, but wasn’t able to mind much good help on this. When I cut PPF, I’m getting some bunching up of the material in the ~10” section between the pinch rollers. It happens the most when the blade moves in the direction away from the edge. My cuts are of oval shape and when the blade makes its way around the finish off the shape the bunching distorts the cut hair and prevents the blade from connecting back up with the cut, leaving a very small area of un cut material. I’ve tried adjusting cut speed down to one of the slower settings and blade pressure down to about 20, but still getting the bunching. Also tried adjusting blade depth up and down with no impact. Additionally, I’ve adjusted the roller tension and all that’s done is leaving roller marks on my liner and material. Any advice??? Thanks y'all!
