Hi folks,

at first, thanks to the developers for their very very great work.

I´m from Germany and in order to save tax and shipping, I decided to build the egg-bot by myself.

Mechanics are out of 2mm laser cutted stainless steel, I devided the electronic to drive a standard stepper board from the china-man ;-)

Everything works very well, I´m really exalted!

Now, after lets say 50 eggs I´ve a problem:

The servo sometimes don´t work, its a wear problem of the poti inside of the servo.
This one is also a cheap China-device. ;-(
So my question: has anyone else such problems with the servo? Are expensive ones are more durable?
Containment action is to vary the upper and lower position or to modify the rod position, but its only a question of time, until the servo is complete out of order...

Any ideas? Thanks for yours anwers!
Best regards,
Vomo

Yes, servo quality varies a lot. The ones that we have are not the very cheapest, but they are inexpensive. One thing that matters a lot is the voltage that you use to drive it. We found (for example) that at 9V, the servo motors would wear out very quickly, and at lower voltages (5 V, say), they seem to work almost forever. Higher voltage causes more wear on the motor, gears, and pot-- so you might try lower voltage on your next one.

Hi Windell,
thanks for your very fast and good answer!

I´m driving with 5V, also.

Okay, I´ll try to get a better one next time.

After Easter, im going to modify my website and show my bot and the differents to yours.

Best regards and good night (its 0:56 in Germany :-)

Is it possible that the load on your servo is much higher from the steel and all?
