Having a problem cutting cast material, it has real rough edges. This doesn't happen when I cut calendered material. Tried blade height doesn't change. Blade pressure same for both materials. Anyone have any ideas what's up.
Install a new blade.
Cast media tends to be a bit more rubbery than calendered. A dullish blade that is sufficient to cut the more rigid calendered can skip and pull on cast media tearing as well as cutting.
Why do people seem reticent to change blades? They're consumables. When a plotter is cutting in some less than optimum fashion, change the blade. If that doesn't remedy the problem, then move on to investigate the more obscure solutions.
If you're a confirmed tight-ass who cannot bear to change a blade unless you know beyond a shadow of a doubt that it might be defective try this. Remove a suspect blade and look at the tip, just the very tip, under a loupe or some other high magnification. If the blade tip does not come to a point, a perfect point, with no rounding, chipping, or any other imperfection or irregularity discernible under whatever magnification you can muster, change it, it's dull.
Don't have a loupe? Get one.
