Well, I'm finally getting around to building a new Z-Axis assembly for my Probotix Asteroid. I've had a terrible amount of slop in the stock setup since I purchased this machine used a year or so ago and have had this design in mind for awhile now. I know there will still be some flex in the gantry, which might be a project for another day, but the Z bearings are my biggest headache. I have made a new plate that replaces the stock piece that connects the upper and lower X axis bearing plates, so this will be a direct bolt-on replacement without having to cannibalize the stock assembly. It should be up and running in another day or two. All milling is being done on my Sherline CNC mill.
The first drawing is the original Probotix setup.
