So after I rebuilt the Z (just re tightened nuts and bolts) the X is PERFECT. the Y WAS perfect, but now its grinding like INSANELY hard.
For instance just front to back is rattles so hard (its not the conduit, they have been worn down) it shakes the bench etc.
When i hit emergency stop the right Y axis carriage offsets a few mm to compensate for how badly it was off.
So my question, can overtightening z axis cause this? the bearings by the looks of things are spinning on the conduit.
Im at a loss… the reason being i ran 4 hours of break in (to wear the conduit etc) and it was flawless the entire time.
