From pre-order to post receiving, the site specs claim the m1 ultra can laser cut opaque acrylics. I've tried white, black and blue at many heights and passes. 100% 2 mm/s and 10 mm height has given me the closet to a cut after 4 passes. Has anyone figured out how to do this or have they just lied to us? I would have gone for the P2 if I had known.
