Our 25" x 33" CNC Router has a single ballscrew moving Y axis. We want to upgarde to dual drive left and right.
We don't really like our ball screw experience (chunky, clunky, noisy, vibration) and are considering going to rack and pinion drive for both sides.
Are there downsides to rack and pinion that I should consider?
Where do I go for parts? I am looking for a well priced commercial source, someone who has stock. I don;t have time for stuff to come around on e-bay.
