I got my Quill DRO installed today and am having a repeatability
problem. Sometimes the scale will stop at -.003" instead of zeroing
out. The repeatability of the scale is said to be .01mm or .0004
inches. I find that hard to believe and figured .001" at best as this
is an import unit. This may me more of a quill problem than the scale.
All in all it is a nice unit for $75. Any suggestion are greatly
appreciated on the repeatability issue. Thanks, Steve

If you're suspecting quill problems, rule those out first. Place a dial or
test indicator under the quill. Zero it at the stop. Test. It should
repeat the zero reading every time. If you still have a +/-.003" variance,
figure out why your stop in not repeating.

If the above method repeats, then your problem is with the DRO/reader.
Check ALL the fastener are tight.
