Most of the effort this week's gone into planning & preparing for the removal of M3.
The other challenge has been to calibrate & test a new, extended Faro probe that will allow us to access the back & outer diameter of M2 through the SAC cage. This is necessary in order to set up the coordinate system now that the pizza pan's in place near the top of the SAC, blocking our usual access.
The longer probe's quite tricky to handle so it's a team sport...
The calibration process is a real patience tester!
Fortunately we're insanely persistent so the humans did eventually triumph :)
