Hi, I have an X Tool M1 5W, and have been looking for the maximum thickness of material I can use in the M1 without risers. Unfortunately my research has been fruitless so far. I have some blank coasters that are 10mm thick and am  hoping that I can still engrave on them.  I am only just starting my engraving/cutting journey, but am eager to learn what my limits are with the M1.
