Our Graphtec FC8600-160 is giving me fits of rage trying to cut Bright Green Controltac 180. I know these letters are on the small side for that material (around 1'') but I can't dial this out no matter what setting I try. I get hangnails on the inside and outside of every perfectly round shape I cut. All letters are cut perfectly, except ones with start/end spots that are catching. I played with overcut, offset, acceleration, force, amount of blade exposed, new blade, swapping the axis - no effect. Sending from GSPPlot and using Gerber Omega 6.0. Are there any fixes or tricks that I could use beyond this?
