I bagged that whole rack-pinion thing for something a bit more robust:


Actually my wife wanted it changed. She used it when we first got it, said it sucks, and suggested the stepper I did, or something like this:



I can send the 3D model of that if you'd like...Uses off the shelf gears from Boston Gear. Uses the same CNC Fusion ball screw.

I've been using the stepper/Arduino thing for years and really like it. I can get accurate depths that hold.

As to the stock mini mill setup, everyone states you should lock the gibs, or tighten them up. Also you can check your rack-pinion mesh and shim the rack to make it a bit more tight.

I didn't like any of those suggestions. A rack-pinion is great for a drill press; not so much for a mill, at least in my opinion...
