good to hear you got it sorted lee! 😛
martin, its good to change the speed now and again for differnt reasons… when you have long long lines of text running we slow the cutter down so when its bounce back and forwards the vinyl is less likely to jam, or track off.
we also slow it slightly for mirror foils and the like…
with reflective we do increase the pressure.
a good thing to do if not alreay doing it is to set the origin point to finish lower left. basicaly where the job started. now when the cutter finishes cutting the reflective you can weed a single letter without taking out machine. just to make sure all is well. if its not! just click start again and the job will cut again but this time exactly over the first one. the second cut is sure to go through. once thats done you increase it a little on pressure.
we do this when running lots of reflective… it just makes sure its always cutting well…
on the subject of reflective, you should keep a spare blade for reflective only. reflective vinyl blunts the blade ten time quicker than normal vinyl.
the reason for this is that reflective contains tiny tiny balls of glass in the material. this is what catches the light and makes it reflect through the colour. hense the reason the blade goes blunt faster…. 🙄
i dont think having a pressure chart would work well…
differnt blades would vary on pressure etc… and even if you used the same blades all the time the vinyl is thicker and thinner with the brands.
personaly ide stick to the small machine test. 😉
