This seemed like the perfect Z axis for my 3018 router , so far I have not installed it. There is a lot of play between the bearings and the connecting rods they slide on. There isn't a setting for it, so I'll have to make my own. I drilled and chiseled holes in the aluminum frame to attach it to my car so I can't return it now. Also the stepper motor didn't work, I ended up using it from the original Z axis. If you buy this you will have to do some work to make it what you are looking for.
