I have been noticing a pattern of scan lines being generated on engraves that show up in regular intervals… is anyone else noticing this as well? I think it might relate to objects being resized from native resolution and then when the “slicing” of the image occurs this is the result. Can anyone chime in on why I’m seeing these lines? My other thought is its related to the dot size chosen and an effect of slicing an image with an odd integer of lines needed to generate code. any help on this issue would be much appreciated, thanks everyone :slight_smile:

Or it is possibly a hardware issue such as step angles of the motors or tension of the belts

Did a bit more testing and I believe it comes from changing the resolution of the image in LW to a size other than the native dpi of the image file

I haven’t come across this yet. What spot size do you use? I’m using 0.1 spot size.

I’d be interested in attempting to replicate your issue, so I’m curious what DPI was the native DPI in the image & what DPI were you changing it to?

There was a bit of discussion in the K40 community at some point a while back to do with something called a moire pattern (if I recall correct) & had something to do with powerline frequency or something like that. Seemed to create replicating patterns in the engraves.

I do adjust / scale / resample my images before and always use 300dpi. Note that now you can put that number in setting and forget about changing the dpi when importing

This is a 1mm square with a dot size of 0.2 , should we be offsetting it like this?
