Reducing Quill Backlash and Setting Z Axis Gain on a RF-30 Mill/Drill

[rog8811]

As I often do when I finish a project, I googled it to see what else similar comes up, your project is about the only one to appear and I read it with interest. I too had, in my case, a Clarke branded mill with a backlash problem, I chose to go the other direction to you as I have pulled the quill up rather than push it down.
I have written this up fully online here Milling machine Quill DRO and backlash eliminator!
I hope it will be of interest.
