Ball Screws or Not That is the Question

[Woodenspoke]

I am looking to upgrade a recently purchased HF X2 to CNC. However I am unsure if I should invest in a ball screw upgrade or just make my own mounts and keep the stock lead screws. I have read posts about backlash with the ball screws that is as bad as the stock screws.


I was looking at the CNC Fusion kit and have read some posts with less than stellar backlash numbers.

Any thoughts especially if you own the fusion kit......

Don' own the fusion kit but the following ball screw threads may help you if you decide to go ball screw route:

Keep in mind, however, that rolled thread ball screws may have lower friction but they may NOT have as low a backlash potential as a ground screw - this is due to the ball to raceway contact relationship.

If you do go with a ball screw upgrade, try to get ones that are ground.
