MasterOfNullI cooked my SG90 mirror arm servo, and I don't have another one just like it. I set the up position too high, so it was stalled the entire time I was figuring out why I lost half my light ring.
It still works, ironically, but it gets really hot now, and moves really slowly. Like 10 seconds per 1/4 rotation slow.
I have the MG90 knockoffs which jitter terribly, and some HS-53 Hitec ones, without arms long enough.
There is some super glue attempting to make the Hitec ones work. Cross your fingers, and I might actually get a video done.
<EDIT>
And I cooked another one. Limits were off by 2.5 degrees. Homing set the servo to 0, which was just outside of the range. Fixed in software now...

Would it not be better (for alignment and less burned out servos) to convert cheaper servos to continuous rotation and have limit sensors at the two extents?

That would work, and would be dead simple/isolated with just two switches and a relay. Did that for my projector screen and you even get motor braking at both extents. However, I don't have the room for the 'extended' limit switch without adding thickness to the base.
If I had re-calibrated it properly, I would not have had this issue. I swapped my A and C axis (mirror/rotation) at the last minute to better align with what Openpnp wanted, and I rushed it due to the contest deadline. This was my fault.
