Re: [CAD_CAM_EDM_DRO] Lead screw compensation

It has been discussed some but having been searching in the
archives I realise how slow it is so a quick remention is in order.

I use inexpensive micrometer test bars. A 12" one is only
about $37 in MSC. Having one I think you can figure out how to
easily replicate more with good accuracy. The combination of stacking these
like gage blocks and using a dial caliper of the same length will give you
.001" absolute accuracy over long distances. Watch the temperature.
