E axis move need help (1 reply)

Hello every one,
I upload newest firmware to my Sanguinololu board.
When I test run 4 motors, only X, Y, Z motors works and E not.
I try change pin between Z and E that still has this problem.
I only test motor move, so I don't attach any sensor or thermistor. I use power and motor to run.
I don't know is that problem? I also try turn off all temperture feature in config file, but result not change.
I'm a newbie so I've still not understood the way it works yet.
Can anyone help me?
Thanks in advance.
