@karrad I cant see any that would conflict with existing parts at first glance, but cant spot many of these in the assembly so I don't actually know what they are and where they are located.
Maybe clarify what "lock" is?

logan added a comment to T10172: E1 doesn't travel down far enough .

I did find one tool head that was hanging out here in MER from an unknown origin that with everything rebuilt straight, was actually traveling less on one actuator (E1). Swapping the actuators between hot ends, the smaller travel distance followed the actuator to E2. This tool head was taken apart to test the jigs related to this ticket, not because it was red-tagged for this issue.
Replacing the actuator resolved the issue. The Z nozzle offset measured by the auto-cal sequence was initially -1.15, is now -0.36.
This difference in travel length could be seen between the bottom rod mount and the bottoms of the motor mounts.

Calibrators @robert @paulette @gregh @newman :
The jig @zachah made has been in use by tool head assembly for a while now. Has the issue of E2 missing the top of the cube been present lately?
If not, I think this ticket can be closed as resolved.
The wiper mount change is still in testing I believe (T8959) and should alleviate being off-center in the wiper pad, and there is another ticket open for the wipe location inconsistency T9468.

logan triaged T9606: calibration OHAI should remove adjustment of backlash as Wishlist priority.

The instructions at step 19 seem to be yielding good results at calibration. Granted, it doesn't include a process to tell calibrators how much backlash compensation to add or remove, but in the interim until Auto-Cal is improved via hardware changes (T9604) or other software changes, this will have to remain.
Lowering to wishlist priority until removing this is feasible for production.
