Initial Testing of Stepper Switch Codes Not Working

I am trying to test the stepper motor and switch mechanism before installation. I think the board may be programmed wrong or is acting up. The first extruder does go to the proper one after 1 second. The quarter second holding does switch between them. When doing the five and a half second holding, it reverses itself on any of the extruders on the next switch hold. When doing the three and a half second holding, the motors just make a jamming sound and don't do anything (it's the one on the right where there are no tubes). I suspect something could be reversed or stuck. I have got it to feed correctly randomly twice the correct direction, only in the first extruder, I have been unable to repeat it,
