Don't get me started . . . Kali - fornia.

Actually, cinco de mayo is really big in California.
Celebrated more than it is in Mexico.

However, the gringo in me didn't realize that when it falls on a Monday, everybody parties for the whole weekend.
Wasn't much happening last night.

Whew! no hangovers.

Hope the admins will stop the nonsense and also remove the offensive phrases. Especially what people do at their private moments, it's not my bussines, nor I care to know. How girls on this forum accept it????

Anyway, on the thread now, I would never put a gear that would multiply the rotational speed on a servo motor. The "play" might be so much that an effect as the one you describe here could happen, and obviously it does. Also as I stated to your P.M. do not use maths in the FOR command. Put directly the number you want, not the 1000/20.

More, the 50 pulses of the FOR-NEXT loop might be little. Try to raise the number to 500.

Interesting. What I found is that starting from 0° and rotating to 360° by using trial-and-error values without stopping in the middle makes the motor stop at very much the same position, ie causing a very close to 360° turn being much more exact than the "return-to-the-middle"-routine. In Short 0° <-> 360° works. 0° -> 180° doesn't. 360° -> 180° doesn't(notice the pointer's(->) direction).

What I found additionally: It is normally not the position that is to be driven to. It is the return. So (RotMin+RotMax)/2 changes its effective position. In other words, even though (RotMin+RotMax)/2 must be constant, the motor does not stop at the same place when being directed to.
