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.

I am using Vectric Cut2d for my designs and have been using EMC2
post processors for the g code creation. Everything works except
that the
text on engravings are somewhat distorted, ie a straight line on
the bottom of an "L" is curved. Also circles are not complete,
there is a very small opening at the ends. All of the distortions
seem to be the identical when repeating an engraved word, so it
seems that it may be more of a code issue than a mechanical issue.
I am wondering if anyone else has had this problem and if there is
a dedicated post processor for machinekit running on a BBB.
