The machine limit is 0,35cm for a line and for holes it can be even less than 1mm, but it can look almost an invisible hole.
The thiner line to the left is the 0,35cm. I make tests in a cloth when I have doubts. This is a test I made for my IQ+Da tee. This is for vinyls, which are easier to cut thin.
Here a tip: you can turn positive the weeding parts and aeparate feom the fills, I mean, extract the letters, in one side, and the cutting drawings in another. Then you can offset a bit the smaller parts of the hollow decorations, so that when you combine them back, you get a wider tiny shape. A bit complicated for me to explain, I hope it can understandable. If you can use a complex vector editor, it’d be easier.
