Whenever I run the Rastankpro its top-grabbing hand servo keeps on overheating and the others do overheat
There are some reasons, why a servo gets too hot:
It runs against a mechanical stop.
- because it wasn’t centered before mounting
- you are asking more travel than the gripper can move (travel limits to high?)
The mechanic is too tight.
- make sure the mechanic runs smooth before mounting the servo
- don’t overtighten screws
Overvoltage
- Make sure the servos can handle the supplied voltage.
