I am pecking a fairly demanding pattern in plexiglas and I was hoping that backlash compensation would fix a subtle, but noticable banding pattern in my dots.
Attached is a photo showing (top) backlash OFF and (bottom) backlash ON. There are some big gaps (0.25 in) in the pattern as well as some completely missing holes. I filled the holes with ink to make them show up better.
Can anyone explain this? My backlash settings are X=.009, Y=0.0065, Z=0, shuttle speed=0.005.
Also, the drilling pattern starts on the left and moves to the right in 1 inch vertical strips. Notice how the patttern is about 1/2 inch longer with backlash compensation turned on due to the skipping.
Thanks
