The problem appears to be a small amount of flex in the linear rods. I used
8mm rods thinking that the stresses wouldn't very much when used as a drag
engraver. I will probably up size the rods to 12mm in the final design
version. The 8mm rods would probably be fine for laser engraving.

Could you post a picture showing the issue ?
You can try with a small hand written GCODE file engraving basic shapes
(circles).
Backlash, if any, should be visible as geometric distortion when the
direction of the motion is changing.

Have worked with the backlash parameter and have observed no differences in
the engravings. Thanks for the info and I will keep playing with the
machine to see if there is
a solution.

Thanks, I will do a little work the backlash adjust. I have never used it
on my main machine, a Probotix Asteroid, but this is on a small engraver I
built and so there may be some issues with backlash etc. I did install anti
backlash nuts on the x an y axis but I may try to go with single start
This sounds mechanical to me (or if the mechanics are already dialed in the
best they are going to get, not measuring and putting in a value for
BACKLASH.
Running on a BBB or not, same gcode.
The default gcode for the 'Machinekit' logo will cut, and then you'll know.
Keep in mind that just t
