I HAVE EDITED THIS VIDEO WITH APOLOGY TO IMAGR FOR INOCENTLY PASSING ON INCORRECT INFORMATION ABOUT THEIR PRODUCT
Before creating this video I have run aliasing pattern trials with other PWM frequencies and discovered that I can get an almost aliasing-free image at 9.999kHz .......just 1 Hz short of the theortically perfect 10kHz PWM frequency.. I then demonstrate why this is happening and what happens at other frequencies..
I run a comparative fox image test with the new found settings and see remarkable differences from the previous attempt. I then attempt somethiing that I had been told would be impossible . The Norton White Tile engraving princple at 1000mm/s
Glass tube engraving has no PWM to drive aliasing errors. but even so, I discuss how aliasing errors could creep in and cause issues. . Desite careful analysis, there was no obvious mechanism that would result in the banding that others had described. I have known a solution to this banding issue for more than 6 years but never understood the mechanism by which banding occured. In this session, an amazing set of circumstances intersect in a way that forces me to apply 6 years of learning to decoding the issue....eventually.
