Things I learned about acrylic: If you use trochoidal, make sure that you have a very good dust collection. There will be big shavings of it and they do not compromise. After the job, my core made hobbling sounds because of acrylic shavings sticking to the bearings, cleaning it was really nasty. Also, on the Y where the bearings roll over the wood, you can clearly see markings the acrylic made in the wood when the bearings rolled over it, picking it up on the way, never letting go because of static I guess. Next time I will definitely be cutting in the middle of the workspace as well as having the dust collection with the bristles up and I will be having some kind of barrier against the shavings to stay away from my Y bearings. Ugh.
