This would solve the ringing problem because the motors would be turning at a constant speed.
Right this is called rastering
I think the peachy printer will be able to do this but it comes it comes with some huge down falls!

1 The print would become much slower as the laser would spend most of its time in the off state.
2. We would need to turn the laser on and off Very Very fast to get great resolutions with this method

Having said that I still want to make the peachy printer do rastering for the purpose of laser light shows!
Good thinking, if we do this jsut right it could actualy take advantage of the ringing!

Currently I have plans to pulse the laser at a photo diode to see just responsive it is.
It certainly possible for 405 nm lasers to be switched very fast but we need to see how the closed loop
current limiter that comes in the laser module acts when pulsed.
