I only added a Limit rotation: X (70-110), Y (-20,20). I suggest changing "Track to" to "Damped track", which reduces torsions around Z. | |

Did you mean you require the angles to move in 20 degree increments (stepped movement), or do you mean that the dish angle total shouldn't go more than 20º to each side from vertical "upwars pointing" position? Stepped progression is probably hard to achieve in Blender, but limiting should be as easy as adding a Limit Rotation constraint to the tip bone. | |

Add missing requirement
|
| Sep 18, 2019 at 9:29 | comment | added | Duarte Farrajota Ramos♦ | Ah you are right, I was aware of the deformation requirement but didn't notice it until now. The disk does seem to be scaling on local Z, but it should be easy to solve. Either add a Limit Scale constraint, or I believe I saw an option for parenting to armature with no scaling, IIRC. Constrained or stepped angles I don't know how to make, not sure they are possible in Blender, at least without drivers | |
| Sep 18, 2019 at 8:03 | comment | added | Nicola Sap | This looks great! I haven't tested it out yet but the gif is quite telling already! Thanks. There are a couple of requirements that haven't been addressed (1. the plate shouldn't deform; 2. the angles should be constrainable), but I think I can figure those one out. I'll report later :) | |
