2015-11-25 02:09:32 -0500 asked a question [Error] Timeout: Aborted finding home position for channel 7

This error message shows during homing process. After that, Finger pinky stopped moving, the motor drived for it got very hot, so I turned off power for security. Anyone who meets simlar problem? How to fix it? And what's the reason?

Here's the message:

Finger Pinky actually moved twice before the error message shows. So the motor drived for it seems has not broken. I also tried to turn the power off and on, shut roscore down, reset several times. However, the same problem still happened everytime.

Anyone who meets simlar problem? How to fix it? And what's the reason?

Any help is apperatiated!!
