Cutting woes!

[Shadowglen]

OK printing on Orajet 3551GRA and laminating with Oraguard 290G so total thickness is 4.75 mil I have a new 45* blade that is clean and swinging freely. force is at 170 grams and the speed I have lowered from 30cm/s to 17cm/s all is good on straight cuts and radius cuts but when it gets to cuts that require tighter turns it is not cutting and lifting the vinyl. The test cut works fine. I edited my cut so that there wouldn’t be switchbacks. As you can see in the pictures I have the cut line of the graphic in 2 spots and the result cut. But it does this all over the decal. Do I need to go slower yet or will a 65* blade be the ticket? Any other suggestions would be great. The machine is a Roland SP540I and the laminator is a Seal 54EL if that matters just trying to give as much information up front.

Dave!

The blade off-set may need to be adjusted as the blade dulls, or maybe there is too much blade stick out. The "thinner" tip area of the 60* will allow thicker material to be cut with less chance of vinyl pulling up at the corners. Personally haven't run a Roland in a few years; is there perhaps a tangential emulation setting for that machine?
I usually slow things down a bit for problematic materials (thick) as well as fine characters or intricate detail
Good Luck!

Use as many pinch rollers that you have when cutting laminated prints. Because you say some of the problems are sharp corners I would strip and wash out the blade holder

+1 on clean the blade holder and lubricate - new cleancut blade doesn't hurt either!

170 FORCE? I have never been over 150, ever.

Get a magnifying glass and check the blade. I've put in brand new blades and had the cutting edge come off within a few inches of cutting. Happened one right after another one morning.

Thanks gang I agree and am now suspecting the blade I will report back.
