Re: [CAD_CAM_EDM_DRO] Re: Rotary to linear translation - an interesting idea.

That is a perfect example of what I am proposing, except you do not need the backup wheel. Just mount it on a slightly flexible
long arm to be able to control the pressure. The encoder would be protected and pre-cleaned by the linear bearings. Build the
housing the whole way from bearing to bearing.
