My team is having trouble with our motor encoders. We had our original encoders that came with the kit. We used them in competition. We then rebuilt our robot for Atlanta, our old encoders stopped working. This week we got new encoders shipped over night. The encoders were working…then they just stopped.
Have you just had any trouble with the encoders? Have any of yours burnt out? Any suggestions?
Thanks
yeah…second time this has happened…called FIRST adn they don’t know why it happens
They seem to be made of spun glass. I don’t know if any of ours work anymore. 
The cords are terrible.
These are general comments for all using encoders. If you have unplugged your cables, most of these could have happened:
The cables are very brittle near the encoder connector. Check for breaks or shorts. I recommned ziptying the cables to the motor body to prevent them from flexing.
Check that you plugged them back into the Motor controller correctly (right motor, right direction) Yellow must be at the outer edge of the controller.
Check that your motor polarity is correct. Reversed polarity will make it “appear” that your encoders are not working. Setting the “Inverse” flag in the software will not correct this problem.
Phil! its a me! bryan! motor encodors rule!
