Ghosting laser while rastering

@paulg4h Did you use input shaping?

[paulg4h]

@o_lampe no, I am not use M593 currently (https://duet3d.dozuki.com/Wiki/M593)

Would this improve it also?

@paulg4h I don't know your engraver mechanic, but resonance from acceleration can be avoided by input shaping.

@paulg4h

thanks for these tests. its great to see the speed/quality improvements.

@gloomyandy how you been incontact with @dc42 about what the changes were and the potential to port this into the main branch of RRF?

[gloomyandy]

@t3p3tony Hi tony, yep I've emailed dc42 with my findings and a link to this thread. There may be a better way to do things than my simple fix (which is literally a one line change), so I'm waiting to see what dc42 has to say.

Thanks to @gloomyandy for identifying this. I agree with the fix he proposed and it will be included in RRF 3.4.0beta6.
