We have been experiencing 'jerky' motion with LW3 and raster engraving to a smoothieboard.

Could you supply me with a test image you are using and I will record my results on a C02 laser

@Alex_Krause We rarely use dithering on images because the contrast response of our original machine was very good.
We normally adjust the contrast and experiment with the light and dark balance to produce a good reproduction on the material we are using.
Here is the test image we are using:

(this image had some dithering already built into it)

+Peter van der Walt​ sent you a message on Hangouts having difficulty following the github responses it’s a rather lengthy issue

@Domenic_Di_Giorgio ​ I will test this image in the morning I’m tired and under the influence of a couple of beers… don’t feel safe trying this out tonight
