Hey Sam, our buddy Dave has already guessed it - I used the new Dyson wheels.
Terry, Its all done with mirrors If your main aim was, for example, raster graphics then the faster the machine (and lower the mass of all moving parts) the better but for vector work, which is my requirement, then the machine can be just as slow as it turns out.
The first little bikes shown were cut too quickly at too much power and the acrylic overheated (boiled possibly) and they had a bad surface finish. Doing them again (lower power, slower feed) produced much better results (these ones are about 20mm long) and this was the original traffic sign artwork.
Tweakie.
