I got to try the xml you updated for me and it does move much better and smooth at that speed...I didn't notice any more incremental raster moves.....tho it still burns the image to much. I'm including links to 2 images and vid from when I tested it.
Image 1 which was done at 1800 mm/min : https://imgur.com/a/q2Ij1
Image 2 which was done at 2000 mm/min : https://imgur.com/a/pRcl9
Video at 2000 mm/min but slowed acceleration to 1800 as it skipped steps once : https://www.youtube.com/watch?v=vGV3vnP ... e=youtu.be
In the images it seems the first 5 squares appear much whiter than the rest then it darkens out.
One thing I notice and you might be able to tell from the vid is when the laser burns the grid of the squares the motor on Axis X also stops/slows for a fraction of a second when it actually burns the lines of the grid....although the rest of the motion is smooth... is this normal? shouldn't just the intensity of the laser change and not affect the motor movement?
