Thank You for yout feedback. I agree....finding that sweet spot for the laser pic can be a bit challenging compared to just on/off but I think I'm getting even closer here
I did adjust the focus more careful and I was able to get better results. On the images below I set the feed rate to 1900mm/min. the pitch is 0.2mm and full range for low/high power.
With the new Mach3 profile for the smoothstepper it start addding raster moves if I go above ~19000mm/min..little but little and more pronouced at around 2100mm/min. Could I e-mail you the smoothstepper xml file one more time and let me know if all my settings are ok?
Here are 2 images of my last tests:

Also what is the best wood the piclaser would work best on?
