Congrats Sumphead! on the pending new baby!
I am by no means as experienced with sumphead on acrylics, but I have cut & shaped acrylics. First thing is that you need carbide tipped tools - and it has to be sharp. Non carbide cutters tends to generate too much heat & make a mess with melted blobs of stuff on the cut line. Feed rate is also important, feed too slow & the cut tend to melt & make a mess. Practice with scrapes to get a feel of your tool's response.
Final result depends a bit on the saw - how much vibration/wobble is there in the blade. But I find there is always slight machine marks on the edges with my saw, so I cut slightly oversized (1/16") & clean up the edge with a router. I use a Porter-cable with a 1/2" straight cut on my router table for that.
I've read about cleaning up the edges on the jointer too. But maybe because I don't have carbide blades on my jointer, the edges don't come out clean.
