Clicking/skipping in which axes specifically? x, y, or both? Is the clicking from the extruder?
* Try using the manual controls in each axis (run it back and forwards 100mm in the middle) and work out which is misbehaving
* Bring the hot end up to temp and try manually extruding 50mm or so, see if the clicking is from this
* We could confirm what's likely with a video of such an experiment
Did you undo/adjust the x/y belts at all? Did you tighten/replace anything other than the extruder-carriage mounting bolts? Friction could be from anything from lubrication (is it all over your hands now?
) to belt misalignment.
