Hi, I have a Mimaki CG-130FX. and I am trying to cut the FabTac painting stencil. I have the pressure set at 17, and it does not quite cut it enough for easy weeding. When I change the pressure to 18, it cuts all the way through the stencil & the backing. The blade that I am using is pretty new, so I do not think that that is the problem. I am using a RoetGuen "easy weed series" Mimaki 56 degree blade. Any suggestions? Thank You
