servo replacement
 

How long do servos last before needing to be replaced in a 90 sized 3D machine?

Are there any warning signs that tells us when a servo need to be replaced? (as opposed to a crash due to servo failure)

thanks

i try to replace the gear set and bearings at least every few seasons or when they show signs of wear. taking the servo out and using your hand to manually spin it from stop to stop is about the best way to check for mechanical problems, on the electrical side you pretty much have to have a feel for the bird and know when it's acting different. sometimes the servos will give a visual indication (jittering) that there is an electrical problem and you can replace it then or send it in for a check over.

I've had servos last 10 yrs and I've had some last a few months both in ideal conditions so there is no set time frame.
