Re: [FTC]: Do Servo's reset during start up?

In labview, servo commands go from 1 - 255. A servo position of 0 means go to the last commanded position. Once you send a servo command, the servo goes there and holds that position. If you don't issue another command for a few seconds, the servo will power down.
Do you agree that the momentary glitch at power up sends them toward the middle 127 (or 8) ?

This is enough to cause issues with buckets dumping or arms unfolding. Setting them to position ahead of time in autonomous may be bad if it takes a long time for the match to start.
