Unfortunately, on the last 0.5 mm pass, I found that the eBay supplier had sent 3 mm acrylic sheet, not 4 mm as I ordered! You will see the larger section come away as the outline is cut. I also didn't put enough tape under it.
On a positive note, the single flute plastic cutter bit performed very well and left a very smooth opaque edge. I will use this for all acrylic cutting in future.
The movie is speeded up x4 to alleviate some boredom or appease the impatient.
