I just bougth a refurbished M1 with an Ap2 purifier as my first Xtool-Laser. The Problem now: where can i find the perfect settings for which material for the purifier? I know, that other lasers can comunicate with the purifier so it can choose the perfect setting automaticly, but the m1 is not able to do this, so i have to manually choose which of the four settings would be the best for which materials. Is there somewhere a list with suggestions or so? or has anyone made experience which would be perfect?
