CNC Knife Plotter cutting the rubber stencil

This is the Roland Knife plotter that we use to cut the letters into the rubber. This is then stuck to the granite memorials, the letters are plucked out and it is ready for sandblasting.

i just used our mimaki plotter to cut resist material and the issue i had was that the even though i had the resist lined up straight when i started the material skewed somewhat while it was cutting. don't know if the physical weight of the material and the fact that i was cutting 90" of it was the problem or the fact that the back of the material against the plotter was so slippery. maybe i need to put transfer tape on the backing material so it's not so slick...

I've used vinyl in the machine for cutting out a few signs etc. I kept the same blade in and adjusted the pressure so that it was very low. However I think if I changed the blade to one with not as sharp an angle (I didn't know they were available at the time) it would cut it alot better. I have a laser etching machine that I use for doing fine etches into granite and tiles, works a lot better than the sand blaster.

have you ever used plain vinyl? would that work? I want to buy a sandblaster but I'm not finding enough info. I need to do this on a large tile surface for a community entrance monument sign.

Thanks for the visuals. Perhaps you could explain something about settings used etc?
