I'm wanting to upgrade the Z-Axis on my CNC Router, it currently is not rigid enough and I'm getting a lot of flex when I cut. I've been looking online at Linear Stage Actuators that I can pick up reasonably cheap, but I'm running into what I believe will be an issue. All the Actuators I have seen come with a metric ball screw, (sfu1605 ball screw, 5mm pitch and 5.08 turns per inch) so my question is can I use the metric ball screw in the actuator for my Z-Axis and continue to use the existing 1/2" 5-start lead screws for my X and Y-Axis's. I know I will probably have to recalculate my driver and stepper for the Z-axis. Unsure of what to do next, any help would be greatly appreciated.
