+2021-11-15 Update:
-* T0-Alpha-Green can automatically level itself, as of today!  Images and video proof are coming soon.  Real life nearly matches the CAD.
+* T0-Alpha-2-Green can **reliably** and automatically level itself, using new flexure joints!  The flexure joints beat the KGLM03 joints in smoothness, as they converge *very* quicky when doing automatic leveling.  
-* CAD and STLs now available.
+* CAD and STLs for alpha-2 are now available.  Nearly all main Z motion parts have changed.  Lessons from alpha-2 will lead to a much simpler alpha-3, likely with even taller Z (beyond 120mm).
+* Different detachable probe options are under testing, including SideSwipe and a stretched Klicky-style probe.

 ### What do I need to build a Tri-Zero Alpha?
 
 For printed parts, you need the STLs in the quantites noted from this repo, along with STLs from a bunch of places:
-- [F-Zero](https://github.com/zruncho3d/f-zero): Z drive units (drive outer, drive inner, motor mounts), no-drop nuts, KGLM-03 joint parts
+- [F-Zero](https://github.com/zruncho3d/f-zero): Z drive units (drive outer, drive inner, motor mounts), no-drop nuts

 Then, go the DoomCube Discord and ask on the #tri-zero channel, because the render and CAD are early and incomplete :-)
