I had documented my desktop machine build (David A's Benchtop CNC Version 2) about two years ago which has been running well so far.

Images below show the latest iteration of my X/Z carriage. If a builder has a design for his machine or has already built the machine frame, this complete X/Z carriage with rotating ball nut drives would provide a simple bolt-on option.

3060 gantry beam and 15mm HiWin compatible linear rails provided by the builder, this package would come mostly assembled and would include everything needed for the X/Z carriage and rotating ball nut linear drives. The cost would be $975 + shipping.

Seeking thoughts, questions and opinions.....
