I upgraded to the Z20 slider. When I home my machine the the Z axis tops out and starts to vibrate like a jack hammer, causing a error! I reset my machine to x50 journeyman and Z20 slider after setup. Is there something I’m missing?I never had this happen with the old slider

If you don’t have an elite machine then you are using stall homing. If it’s reaching it’s limit and not homing then you most likely need to reduce the current. This video should help.
