This is a Bolton Tools ZX45 Mill that I converted to CNC using Nema 23 steppers for X and Y axis and a nema 34 for Z axis. The racket you hear is the gear mesh vibration of the hand crank 45° gear on the Z axis ( I still use it as a manual mill sometimes).
you won't get accuracy with that saddle hanging off of the ways.
