 Brake/Coast Not Working Hello, We finally got our FTC kit so I get to play with all the bells and whistles of it for a few days. Though, when I started to play with it, I noticed that I could not set the 12V DC Motors to coast or brake. The line of code below does nothing. Is this a bug or am I missing something? Thanks -Tanner

Re: Brake/Coast Not Working Hey,
We've been having the exact same problem. Hopefully by bumping the thread there will be a reply.

Re: Brake/Coast Not Working I know, It makes you feel stupid when it's just you and an isolated problem. Have you had any problems with a servo testbed?

Re: Brake/Coast Not Working We haven't gotten to test any Servos yet, but I have not heard of any problems.

Re: Brake/Coast Not Working The Brake/Coast variable is meant for NXT motors, not for the FTC motors. The motor controller does not allow us to select "coast/brake" mode, so you'll have to kludge it.
Apply a speed of "1" to get the FTC motor to coast, and a speed of "0" to get the FTC motor to brake.
