Assuming 10 mil = 10 thou, that's about 0.25mm, so not very wide.
They'll do it (resolution of a thou is common), but the limit is the vinyl
itself. With long thin stuff like traces the probability of stuff lifting
or moving around is pretty high.
Using the plotter to cut the copper itself like the OP is doing is a
different story. The CriCut won't have the accuracy of a Roland, but you'd
expect that.
