  Downside to that I guess is it would add a 200us delay in the laser power stream...

Ill Dwell on it... Smiley

Hi Art,

That is the way of life - "nothing is ever simple and there is always a catch".

More electroni cs but could you perhaps introduce an equal delay in the axis movement ?

Ill have to give it more thought. Ironicall y I put in a laser
delay in Auggie for servos that are slow to react, but I hadnt
considere d the inverse.

First try at a single pass 3d , 1.5" round. Took less than a minute.
  Not great detail, but its small on pine..

Art,

Do you have a link to your Arduino code used for the DAC signal conversio n?

Saw your youtube video and want to give this build a try with my diy style galvo motors.

Thanks

Hi Brian:

 I hadnt posted it yet. It is attached to this post though. Let me know if you have
any trouble with it, I cant recall if I modified any system libraries as tweaks to make it
work faster.

   I havent cleaned it up and documente d it yet, so its a bit messy.. Smiley

 The following zip contains a new winterrup ts.c required for compiling the code in the previous post.
Also a wiring list for the arduino is included.
