Letters peeling

[may0024]

I have a Seiki 870T. When I try to cut smaller letters on Oracal 631 and 651, the blade peels them off. I typically cut at 100 speed and 210 force, but changed speed all the way down to 20. Anyone have the same experience and have ideas that could help me?

TIA

  How small is small lettering?   Is your vinyl pretty fresh? Yes, you should change your speed down,  also maybe is your blade too far out? Did you try  raising the blade any? then using the force to make your cut.   Is it cutting into the backing paper?

I had this problem when my blade was sticking out too far.  I also noticed that once this has happened, frequently pieces of vinyl get jammed up in the blade holder making the problem worse.  I would take the holder apart, clean, and put back together.  Check blade depth and try again.  Small letters I cut at speed 8-12.
