I've had that problem with my el cheapo HF table topper, and found that I needed to either adjust the split nuts to reduce the lash again, or fine tune the backlash settings. Even now, I can cut a socket for a ball bearing and while I can see this reversal artifact, its been small enough that by the third time I've pushed the bearing in and out while fitting other pieces of the work, the reversal artifacts seem to be pretty well polished away. I can't find them with a caliper, .0002" dial, or a .0005" digital. If you can measure it, you may be able to adjust the backlash in the .ini file and fix it, adding or subtracting half of what you can measure at any one time. >-------------------------------------------------------------------------- >---- Download Intel® Parallel Studio Eval >Try the new software tools for yourself.
