stepper motor and FPGA question about pins assignment

Hi everyone. My mission this week is to make a step motor move by FPGA I need to program the FPGA to send out a pulse, and i plan to use the clock to send a 3.3V and then connect to the stepper...

Without the motor specs it's hard to say. It may be the drive requirement is more than the FPGA can provide, or your clock is clocking faster than your motor can respond to.

First things first however.

With the motor disconnected, you you see with an oscope the clock output when the motion pin is in the correct state?
