I'm just now starting to use my DSP from Lightobject.
I see you are changing your scan gap for different media. Maybe I'm confused (wouldn't be the first time...)
I thought you'd set your scan gap to whatever your system is built to. For instance, my system is built so that both axes are 1000dpi. So, 1 step (or scan line) would be .001", or .0254mm. It looks like the closest I can set the DSP is .03mm. I'm getting pretty good scans wih it set there.
Could you elaborate on your thought process with this (since we have SUCH A GREAT MANUAL with the blue-panel DSP... not.)
Thanks!

A couple of things you want to consider:
1. What is your (focused) beam size? The best you will ever get is to set you scans so that your spots do not overlap. Certain materials (granite, etc) may actually benefit from a little overlap or even a little space between scan lines, since granite, marble, glass, etc all work by exploding chunks of material from the surface.
2. Speed is a concern. If you set to .03mm, it will take you about 3.33 times as long to run a job as it does at .10 (the default) setting.
What Tim is doing is setting to .09, which is probably giving him a slightly smoother output, eliminating any possible ridges between scan lines.
All in all, you have to experiment with your laser, your material, and your time. Then use what works best for you. Don't know how you would put that in a manual.
