Hi, so I crashed my cobra42 and after fixing everything, I'm noticing what seems to be a step in the z axis travel, it's noticeable when cutting too, if I cut an angle, there's a visible line at the same point in the z travel. I checked with a dial indicator and it hangs up when jogging manually for 3-4thou... I'm assuming this isn't a backlash issue... is there some other possibility before I go searching for a Z ballscrew for it?
 
I would look for something (maybe a ding) on the slide or guards hanging up. Something causing resistance then letting go when past that point. Seems like a flat spot on a ball would not repeat at exactly the same place indefinitely.
