3M prismatic reflective vinyl

[straydergame 0]

Hello, we recently bought 8600-160 Graphtec cutter, with all recommended knifes, 6 pinch rollers, knife holder etc, but we still have problem in cutting 3M prismatic vinyl. We have problem on all 3 classes of 3M.

 

Biggest problem we have is cutting circle, square ,and other bigger shapes (size 60x60 or 90x90cm). First question is does any1 know how to registrate marks? We know that prismatic vinyl can reflect data for sensor reading, but there must be a way to somehow machine reads marks and starts cutting. We have tried to manually position knife and make its Origin place, but it doesnt work, no matter what, it cuts out of shape at some point.Distortion by X (if it was supposed to be 60cm, it used to cut on 59cm) we fixed that by putting Distance adjustment in RIP by 1.15 and it works. So basically we have problem to make it read marks, or align vinyl very properly or whatever is the issue so drawaing for cutting in RIP matches on vinyl, without going out of shape.

 

If any1 using it for cutting prismatic 3M viny please help us out. That is our main job, so if it can't handle it we will need to return machine.

 

Thanks in advance

Is it just not getting through it? Have you tried making a second  or third pass? I cut some hard material a while back for paint stencils and couldn't get clear through it consistently so I opted to go for a double pass. The only tricky thing was figuring out what pressure to use because the text feature in my Summa is designed around a single pass so it took an educated guess and some fine tuning to get there.

try making the marks darker or thicker that way the sensor has a larger field to work with

You can try putting some matte finish scotch tape over the marks to reduce glare.
